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.
If you have any questions about out Composite Prepregs product line please let us know. We are readily available to discuss you application, learn more about your needs, and address any questions.
