Composite Prepreg Features

Processing – Axiom Materials prepregs are formulated for processing in autoclave, press and out of autoclave (vacuum bag / oven). Our products are tailored so that they can be cured at low at 170F and as high as 350F with higher post-cures as needed.

 

Flexibility – Axiom Materials prepregs can are made to be flexible in the tack, drapability, resin content, color, flow and volatiles. These prepregs are manufactured in both hot melt and solution coated tower processes.

Client's Feedback

NIAR Automated Technologies Laboratory for Aerospace Systems (ATLAS) partnered with Axiom Materials to investigate the automated fiber placement (AFP) of AX-7810UD-330N610-0.5", a solvent-based Ox-Ox Ceramic Matrix Composites (CMC) unidirectional slit tape that can be used for high temperature applications up to 1,650 °F, such as engine components. Several variants were slit using a NIAR slitter, capable of continuous in-process inspections to investigate the slit-tape quality in order to ensure that the material will process through the AFP system without any manufacturing defects.   "Working in partnership with the technical team at Axiom Materials, we were quickly able to implement several improvements to the AFP system in order to precisely process slit narrow tape CMC materials efficiently," said Josh Goertz, a senior research engineer at ATLAS who has over 10 years of experience with AFP systems.

Composite Prepregs FAQs

  • Composite prepregs are fiber reinforcements that have been pre-impregnated with a controlled resin system. They are used to manufacture composite structures with consistent handling, controlled resin content, and repeatable processing characteristics.

  • Axiom Materials manufactures composite prepregs using resin systems such as epoxy, phenolic, polyester, cyanate ester, polyimide, and bismaleimide. These prepregs are available in woven, stitched, and unidirectional forms.

  • Axiom composite prepregs are available with woven and non-crimp fabric reinforcements, as well as unidirectional fibre reinforcements. We also offer off-the-shelf prepregs and customizable options for width, length, tack, and color.

  • Axiom prepregs are formulated for autoclave, press, and out-of-autoclave processing, including vacuum bag and oven processing. Cure options range from low-temperature cure systems to snap cure systems as well as 350°F cure systems, with higher post-cures as needed.

  • Axiom Materials enable a wide variety of applications across several markets, including aerospace, automotive, medical, marine, military, sports and recreation, infrastructure and construction, and industrial applications.

  • Yes. Axiom can tailor materials for tack, drapability, resin content, color, flow, volatiles content, width, and length. Customers should consult Axiom’s technical team to evaluate available customization options for a specific application.

Epoxy and BMI tooling prepregs

Epoxy tooling prepregs

Composite tooling programs where process flexibility, surface quality, and reliable handling are the main priorities.

AXIOM epoxy tooling prepregs support composite mold-making applications that require dependable processing and finished tool quality. They are a strong fit for teams looking for practical cure options and consistent laminate behavior during tool fabrication.

BMI tooling prepregs

Higher-temperature tooling applications where a BMI resin system is preferred for the production environment.

AXIOM BMI tooling prepregs are formulated for more demanding tooling requirements where elevated-temperature performance is part of the specification. They help manufacturers build tools for composite programs that place more stress on the tooling system.

Carbon fibre prepregs

Structural composite programs that demand high stiffness-to-weight ratios and consistent fibre-resin distribution.

AXIOM carbon fibre prepregs deliver predictable layup behaviour and reliable consolidation across a range of cure cycles, making them well suited to aerospace, motorsport, and industrial structural applications.

Glass fibre prepregs

Applications where cost-effective reinforcement, electrical transparency, or corrosion resistance drives material selection.

AXIOM glass fibre prepregs offer versatile processing options and reliable mechanical performance, supporting a broad range of structural and semi-structural composite programs.

Surfacing prepregs

Programs where finished surface appearance and paint-film quality are primary requirements alongside structural performance.

AXIOM surfacing prepregs are engineered to minimise read-through and produce a consistent, low-porosity surface layer, reducing post-processing time and improving cosmetic quality.

Aramid tooling prepregs

Impact-resistant tooling and structural applications where toughness and energy absorption are key performance criteria.

AXIOM aramid prepregs combine lightweight construction with high damage tolerance, making them a practical choice for tooling and components exposed to repeated mechanical loading or impact risk.

Product feaDesigned for mold-making programs using autoclave or out-of-autoclave processing.tures

A tooling prepreg has to do more than cure. It has to handle correctly, lay up cleanly, and produce a tool surface that does not create problems later in production.
