Reinforced structural plastics
Reinforced polyimide structures are described. Reinforcing materials are impregnated with a suspension of polyimide prepolymer and bonded together by heat and pressure to form a cured, hard-reinforced, polyimide structure.

Thermally stable laminating resins
Improved thermally stable laminating resins were developed based on the addition-type pyrolytic polymerization. Detailed monomer and polymer synthesis and characterization studies identified formulations which facilitate press molding processing and autoclave fabrication of glass and graphite fiber reinforced composites. A specific resin formulation, termed P10P was utilized to prepare a Courtaulds HMS reinforced simulated airfoil demonstration part by an autoclave molding process.

Development of a low void polyimide resin for autoclave processing of glass and graphite reinforced composites.
Experimental studies are described in which new A-type polyimide prepolymer chemical modifications were investigated with the aim of increasing the melt phase duration and temperature range permitting autoclave processing, yet retaining the addition-type cure mechanism required for low-void content composites. Several modification candidates were examined, and one specific formulation was selected for detailed investigation. This A-type polyimide prepolymer formulation is shown to possess the desired characteristics.

Polyimide polymers provide higher char yield for graphitic structures
Technique for manufacture of graphite composites uses high-char-forming processable polyimide resin systems to produce the graphitic matrix. Only three cyclic steps are required to yield a 99.7 percent graphite product.

Polyimide polymers provide improved ablative materials
Principle heat absorption of silica-reinforced plastic ablative materials occurs from the in-depth reaction of silica with carbon to form silicon monoxide and carbon monoxide. The higher the degree of completion of this reaction, the higher the capacity of the ablative material to absorb heat.

New rapid-curing, stable polyimide polymers with high-temperature strength and thermal stability
Additive-type polymerization reaction forms thermally stable polyimide polymers, thereby eliminating the volatile matter attendant with the condensation reaction. It is based on the utilization of reactive alicyclic rings positioned on the ends of polyimide prepolymers having relatively low molecular weights.
