Abstract:According to characteristics of vacuum-assisted RTM process,processing parameter of the powder filler
introduced resin-based composite materials were detered. The powder filler is dispersed in ethyl acetate solution,dispersant
and binder were added to prepare a good dispersion of the powder filler suspension, and the quality of the powder
fill and dispersant were detered to be 1 ∶0.5. Quantitative spraying the powder filler reinforcement fibers in order to modify
the composite,and analysis the effection of the powder filler is dispersed in the solution and bonded state of the reinforcing
fibers. SEM observation reveal that the modified fibers,powder filler can relatively uniform adhesion in the fiber
surface. Due to the powder filler adhesion in the fiber surface,breaking srength of failaments reduced about 10%.
