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 graphitepolyimide in this type structure. Design allowable data for tension, compression, and inplane shear were developed at both room temperature and 550 F.
