scope:

This specification establishes the general requirements for thermosetting polymer matrix, unidirectional carbon fiber prepregs. Specific requirements for the prepreg material are governed by this document along with the applicable specification sheet. This specification contains qualification requirements. Qualification pertains only to the requirements of this specification and does not qualify the material for use in the fabrication of a structural component in a particular system. Qualifying a material for use in the fabrication of a structural component requires additional testing requirements as determined by the government and the system manufacturer (see 6.3).

The various classifications of the prepreg material are covered in each individual specification sheet. Each specification sheet covers a particular prepreg material according to the matrix type and carbon fiber properties (see paragraph 6.8).

intended Use:

This material is intended for use in the fabrication of airframe, aerospace, or related primary or secondary load bearing structures where high strength/weight and stiffness is required.
