摘要：

Short carbon fiber-reinforced polyimide composites were prepared by wet impregnating chopped short carbon fibers with PMR-15 polyimide matrix resin solution followed by evaporating the solvent with strong stirring. The processing properties of the composites molding powders were investigated. The mechanical properties and thermooxidative stability of the composite laminates fabricated were also studied. Experimental results demonstrate that the short fiber filled molding powders exhibit good melt resin flowing characteristics and can be proceed by hot press molding technique to produce small-size, complicated composite structures which are difficulty to be produced using long fiber reinforced composite prepregs by autoclave technique. Some small components, bearing hoses, were fabricated and tested for the potential applications in aeropropulsion systems.
