This specification contains qualification requirements. specification and does not qualify the material for use in the fabrication of a structural component in a particular system. Qualifying a material for us
4、e in the fabrication of a structural component requires additional testing requirements as determined by the government and the system manufacturer (see 6.3). Specific Qualification pertains only to the requirements of this 1.2 Classification. The various classifications of the prepreg material are
5、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). 2.
