Prepregs

Description and benefits

  • Made of our own in-house developed carbon fabrics and resins.

ITECMA developed their own product line of high quality prepregs with service temperature up to 300°C.
Pre-preg is "pre-impregnated" composite fibers where a thermoset polymer matrix material, such as epoxy, is already present. The fibers often take the form of a weave and the matrix is used to bond them together and to other components during manufacture. The thermoset matrix is only partially cured to allow easy handling; this B-Stage material requires cold storage to prevent complete curing. Hence, composite structures built of prepregs will mostly require an oven or autoclave to cure.

We also try to keep up to date, taking into consideration all composite industry development factors, and developed Out-of-autoclave prepreg ITECMA B180, having 95% of autoclaved prepreg characteristics.
