This specification establishes the requirements for a nominal 250 \mDF 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 \mDF.

The composite may be used for the manufacture of primary and secondary aircraft structure.
