Industry Insights: Why Dry Process May Be Your Best Composite Epoxy Solution

When it comes to composite manufacturing, you can choose from many materials and methods, each with unique advantages. Among the choices, two techniques stand out: the dry process and pre-impregnated (or pre-preg) process. Understanding the differences between the two will help you settle on the most effective way to bring your project to life.

Here, we’re comparing the dry process versus pre-preg to shed light on their characteristics and applications. From cost efficiency to customization to performance, you’ll learn that the dry process is often the best composite epoxy solution. 

What’s the difference? Dry Process vs. Pre-preg Solutions.

Dry process and pre-preg solutions are two common methods for applying epoxy resin to fabric substrates. Each method comes with its own characteristics and applications.

Dry Process

In the dry process, a raw carbon fiber tow or fabric is loaded into a mold and epoxy resin is used to saturate the substrate. The resin then cures, bonding the fibers together to create a solid composite structure.


  • Requires separate handling and application of resin and dry fibers
  • Offers flexibility and customization in material selection and layup techniques
  • Can reduce material waste and enhance performance
  • More cost-effective and compatible with automation compared to pre-preg solutions

Pre-preg Solutions

Pre-preg refers to a composite material where reinforcing fibers are pre-impregnated with a resin before use. This pre-impregnation is typically done by the manufacturer, who applies a precise amount of resin onto the fibers and then cures them to a partially cured state. The pre-preg materials are then stored in a freezer until they are ready to be used. When heated, the resin cures, bonding the fibers together to create a solid composite structure.

  • Characteristics:
    • Reinforcing fibers are already impregnated with resin, simplifying handling and processing
    • Requires freezer storage to prevent premature curing
    • Offers consistency in material properties and performance
    • Typically more expensive than the dry process due to additional processing and handling

Both dry process and pre-preg solutions have their advantages, and the choice between them depends on cost, production volume, and performance specifications. The dry process offers several benefits that make it the best choice for most applications:

  • Cost Efficiency:

The dry process involves lower material costs compared to pre-preg solutions. Pre-preg materials are often more expensive due to additional processing and handling.

  • Customization:

The dry process allows for easier and faster customization and flexibility in material and techniques. You can tailor the resin type, fiber orientation, and layering technique to meet specific requirements and optimize the finished product. 

  • Reduced Material Waste:

 With pre-preg solutions, unused or excess material can lead to waste due to limited shelf life, resin wasted in pattern cuts, and storage requirements. In dry processing, the fibers and resin are combined in the mold as needed, which reduces waste and limits your environmental impact.

  • Improved Handling and Storage:

Dry materials are easier to handle and store than pre-preg solutions, which require storage in freezers. This simplifies logistics and reduces the risk of material degradation during transportation or storage.

  • Faster Production Times:

Pre-preg solutions require additional processing steps and curing time, while dry processing offers faster cycle times and increased efficiency. The dry process allows you to streamline production without compromising quality.

Assessing Supplier Responses

As you evaluate potential partners, pay close attention to their responses to these questions. Here are three red flags to watch out for when assessing supplier responses:

  1. Lack of Transparency: If a supplier is vague in their responses, it may indicate a lack of transparency or a reluctance to engage in open communication. Beware of partners who won’t speak openly about their capabilities and processes or how they work through potential challenges.
  2. Limited Technical Expertise: A supplier who offers limited access to technical experts or is unwilling to share their expertise may not be equipped to provide the level of support you need. Make sure your partner is committed to providing help at every turn.
  3. Inflexibility: Partners who resist experimentation, testing, or exploring new solutions may hinder your ability to adapt and innovate. Look for signs of flexibility, openness to new ideas, and a willingness to collaborate on solutions that drive mutual success.

When you watch for these red flags, you can better assess the fit of potential suppliers and identify the right partner who will be invested in your success. Choose a supplier who listens to your needs, freely shares expertise, and demonstrates collaboration. Steer clear of those who signal they’ll operate on their own agenda.

Reinforcements: Putting it All Together

Your job, your product, your needs are unique. What’s not unique is the fact that epoxy resin alone typically doesn’t provide enough structural integrity to meet the reliability and durability you need.

We cater our epoxy development to create a low-density material with a high strength-to-weight ratio to meet the needs of diverse applications specifically with each of these types of reinforcements:

  • Carbon fiber
  • Fiberglass
  • Aramid
  • Natural fibers: jute, flax, and kenaf
  • Exotic fibers: boron, basalt
  • Particulate fillers: ceramic, silica, metal

Properties and Advantages of Different Reinforcements 

Each reinforcement material offers its own unique characteristics and benefits. The best material for your specific application depends on its intended use. Some of the most common properties reinforcements offer include:

  • Impact resistance
  • Stiffness
  • High strength-to-weight ratio

Not Just a Manufacturing Process. Your Process.

For every type of process, there’s a set of variables that come into play – as well as the desired outcome. That’s why we develop products not just for the process type, but for the individual customer variation within each process type. That’s what makes Copps unique.

Through customer collaboration, meticulous attention to detail and precision, we develop products for all of these processes:

  • Vacuum Bagging: An open molding technique (including Wet Bagging) that places mechanical pressure on a laminate during its cure cycle. Designed to achieve higher-than-normal properties of Hand Layup without the technical challenges of VIP.
  • Hand Layup: The simplest composite molding method available where fiber reinforcements are wet out by hand and manually positioned into a mold.
  • High-Pressure Resin Transfer Molding (HPRTM): Rapidly becoming popular in the automotive, industrial, and agricultural industries, this is a high-output process where dry reinforcement fabrics are placed into metal tooling inside of a high-tonnage hydraulic press. Resin is then injected under very high pressures for precise part geometry and repeatability. It can also be automated in a 5-step process.
  • Light Resin Transfer Molding (LRTM): A closed-mold process similar to resin transfer molding where both the A and B molds are made of composites. This technology is frequently applied in production of boats and water equipment but has infinite possibilities beyond, including car body elements, trailers, aircraft, and more.
  • Vacuum Assisted Resin Transfer Molding Process (VTRM): Another variation of RTM, this too is a closed-mold manufacturing process. Unlike LRTM, the top portion of a mold tool is replaced with a flexible vacuum bag, and vacuum only, no injection, is used to assist in resin flow. Currently most used in composite production where only one part of the laminate is visible.
  • Vacuum Infusion Process (VIP): A low production-level, closed-mold process with a single-sided tool that is loaded with dry fabrics. A flexible film is then used to apply full vacuum to the part and the resin is drawn into the reinforcement through the vacuum applied. Popular infusion resin types include epoxy, polyester, and vinyl ester.
  • Filament Winding: The process of winding resin-impregnated strands of fiber around a rotating mandrel to create a composite structure. Creates high-fiber loading with good directional strength for extremely strong composite products.
  • Pultrusion: A high throughput process for making straight solid shapes where dry fibers are dipped in resin and pulled through a heated metal die creating the part profile and curing in one step. Best suited for high-volume, single-direction reinforced products like rods, poles, trim, flat panels, and more.

Regardless of the method to suit your process, our quality control and testing are vital to ensure the final product will meet the required standards.

Polyurea vs. Polyurethane: Similarities, Differences, and Applications

Polyurea and polyurethane are ideal for manufacturing protective linings and coatings. The two materials share many similarities and can often be used interchangeably. However, there are several distinct differences that should be considered when choosing between the polymer compounds. From chemical composition to curing time, these differences lend unique advantages and disadvantages depending on the intended application.

Polyurea vs Polyurethane

Polyurethane and polyurea share many similarities — one of the biggest being that, in their final forms, they are capable of curing into very flexible to very stiff coatings. Polyurethane has been a standard sealant and adhesive material for decades. It is created from a reaction between a polyol and an isocyanate, creating a waterproof coating with high resistance to certain acids. This makes polyurethane ideal for use in the food industry, where frequent contact with food-related acids is expected.

Polyureas are a more modern addition to the sealant and coating industry. They are formed when multifunctional amine reacts with an isocyanate. The compound reacts faster than polyurethane, creating a gel in only seconds after mixing the ingredients.

Advantages and Disadvantages of Polyurea vs Polyurethane

The unique compositions of the two substances provide them with advantages and disadvantages based on the application. Both compounds are ideal protective coatings for concrete, reducing the damaging effects of chemical exposure, corrosion, abrasion, and moisture. Polyurethanes offer the following advantages:

  • Facilitates application in two parts for more versatility
  • Less expensive than polyurea
  • Resistant to damaging UV rays
  • Curing time can be set from one minute to several hours depending on the mixture

Polyurethanes also have unique disadvantages compared to polyurea coatings. When applying polyurethane, users must pay attention to the temperature and humidity level. The chemical reaction is sensitive to temperatures less than 32°F. Polyurethane coatings may blister when applied at humidity levels higher than 70%.

Polyurea offers the following advantages:

  • Pleasant appearance with various pigment options
  • Easy to work with
  • Applicable at temperatures as low as -20°F
  • Performs well in humid environments
  • Quick curing time allows for application in harsh conditions
  • Withstands extreme environments

Several factors put polyurea at a disadvantage compared to polyurethane. Polyurea can be expensive to apply because technicians must be highly trained to work with the incredibly fast-curing compound before it sets. With little resistance to UV damage, the appearance of polyurea can become chalky, discolored, and dull when exposed to UV rays.

Applications of Polyurea vs Polyurethane

Polyurea and polyurethane’s unique characteristics make them ideal for use in differing applications. Polyurea’s resistance to harsh environments makes it ideal for construction applications. It is suitable for bridges, car parks, decks, roof repairs, and aesthetically appealing surface coatings for floors. The oil, coatings, marine, and other industrial industries depend on polyurea for a wide range of uses.

Polyurethane’s low cost and manageable application make it suitable for cars, furniture, housing, and shoes. It can also be used in manufacturing hard protective coatings and foam insulation for mattresses.

Polyurea vs. Polyurethane Coatings From Copps Industries

Polyurea and polyurethane are valuable coating and lining compounds for many industries. While polyurethane coatings are affordable and offer UV resistance, they are more susceptible to damage in humid or freezing environments. Polyurea resists extreme conditions and cures incredibly fast but can be more expensive.
