Develop Fabrication/Processing Techniques for High Temperature Advanced Composites for use in Aircraft Structures

Abstract

The objectives of this program were to place polyimide matrix advanced composite processing technology on a production basis, and to demonstrate its acceptability for structural applications by fabrication and test of representative structure. Under this program polyimide matrix advanced composites were cured in a one shift autoclave operations (-8 hours) at 350 F and 200 psi maximum while maintaining epoxy matrix-type properties. These process parameters were confirmed by the successful fabrication and test of an F-4 polyimide rudder, which demonstrated the flight worthiness of thin gauge boron and graphite/polyimide in this type structure. Design allowable data for tension, compression, and inplane shear were developed at both room temperature and 550 F.
