Abstract:The F-8H3/602 aramid fiber reinforced composites laminates with different content of epoxy resin
were prepared. The effect of resin content on impact toughness, interlaminar shear strength and flexural properties
were studied. The morphologies of damaged samples were observed by microscope and scanning electronic microscopy
(SEM). The results indicated that impact toughness, interlaminar shear strength and flexural properties were close re鄄
lated to the resin content of aramid fiber reinforced composites. For F-8H3/602 aramid fiber reinforced composites
with 46. 02wt% resin content, the impact toughness, interlaminar shear strength and flexural strength were 22 J/ cm2,
49. 1 MPa and 506 MPa respectively. At certain weight content of resin, the mechanical properties of aramid fiber re鄄
inforced composites in 0毅direction were much better than in 90毅direction. The interface between fiber and matrix of F
-8H3/602 composites was weak according to SEM images of samples.
