Scope: This specification covers the requirements for filled@ resinous thermosetting compound and sheet pre-preg to fabricate shims for use during assembly of aircraft and marine components and parts. Classification The material shall be classified in the three types as specified: Type I - A two component material (base and hardener) which@ after mixing and application of heat (350 ??@ will cure to a hard@ strong resin. Type I material may also be cured in ambient temperature of 75 ???? 5 for a period of 96 hours minimum. Type I Class A - A two component material (base and hardener) which after mixing may be cured to a hard@ strong resin in ambient temperature of 75 ???? 5 for a period of 9 hours. Type II - A precatalyzed (B-staged) sheet material which will cure to a hard@ strong resin with the application of heat. Type II material may also be cured in ambient temperature of 75 ???? 5 for a period of 96 hours. Type III - A precatalyzed (B-staged) material supplied frozen in a tube from which it can be extruded and cured to a hard strong resin with the application of heat (200 ??. Type III material may also be cured in ambient temperature of 75 ???? 5 for a period of 96 hours minimum.
