This specification establishes the requirements for a nominal 250 °F cure epoxy preimpregnated carbon fiber plain weave fabric product. The prepreg is a plain weave fabric with 12K tows, a nominal fiber areal weight of 193 gsm, and nominal resin content of 42%.
The purpose of this specification is to allow procurement of a defined material corresponding to the statistically derived material properties published in MIL-HDBK-17.
This material is intended for use in laminate applications with a service temperature of -65 to 180 °F.
The composite may be used for the manufacture of primary and secondary aircraft structure.
Widely distributed and available industry material specifications are required for procurement of composite materials whose allowables data is published in MIL-HDBK-17.
