What are prepregs?

Prepregs are composite materials in which strengthening fabrics, like carbon fibre, fibreglass, or aramid, are already impregnated with a resin system, typically epoxy. This eliminates the need for purchasing, storing, and manually mixing complex resin systems. This not only saves time but also minimises waste and simplifies the entire workflow. 

Benefits of using prepregs

Ready to take your composite project to the next level? Our prepregs are the key.

Improved efficiency:

Prepregs streamline your fabrication process by eliminating the need for complex resin system management. This translates to reduced labour costs, material handling, and potential for material waste.

Consistent quality:

Prepregs guarantee a uniform resin-to-fibre ratio throughout your laminate. This leads to predictable and reliable mechanical properties in the final product.

Reduced waste:

Prepregs minimise material waste by eliminating the possibility of mixing errors or improper resin application.

Superior performance:

Prepregs often contain higher-quality, resin systems with more complex formulations. Compared to traditional hand layup techniques, this can improve void content and overall mechanical properties.

Types of prepregs GMS offer

We offer a diverse range of prepregs to cater to your specific project needs. Choose from:

Carbon fibre prepregs:

Available in various weaves, fibre types (high-strength, intermediate-modulus, high-modulus), and resin systems to suit your application’s specific requirements.

Fibreglass prepregs:

A cost-effective solution for applications requiring good strength and chemical resistance.

Aramid prepregs:

Ideal for applications demanding high-impact resistance and excellent ballistic protection. Popular brands of Aramid prepregs include Kevlar® prepegs and Twaron®

Explore our complete selection in our list of prepregs. Beyond these core options, we can also work with you to source specialty prepregs based on your unique project needs.
