manufacturing Carbon fiber prepreg

Prepregs

Prepreg is a widely used term for carbon/kevlar/glass fiber cloth impregnated with a controlled amount of  Epoxy resin. CA Composites provides a wide range of prepregs made from Carbon fiber, Fiberglass, and Kevlar for aerospace and industrial applications.

The prepregs are prevented from curing by storing in freezers.  Ours can also be stored at room temperature for about 4-5 weeks. This is why our prepregs can be transported without freezer bags.

Prepregs need to be cured at very temperatures to obtain the required shape and strength. Our Prepregs can be cured at 90-150 degrees celsius.

Unlike others, all our prepregs are protected with wax paper on one side and PE film on the other. This helps prevent dust and enhances the surface look of the cured parts.
