Punching shear properties of selected glass-fiber reinforced polyester under both static and impact loadings were investigated. A modified Split Hopkinson Pressure Bar Method was applied to the impact test.
The test results were as follows.
(1) The impact shear strength is about twice as high as the static shear strength of the same material.
(2) Under impact loading, the law of mixture holds approximately.
(3) The impact shear strength is influenced by the textile structure of fiber reinforcements.
(4) The residual deformation of glass-fiber reinforced polyester at fracture is larger than that of the matrix itself, and it is influenced by both the textile structure of fiber reinforcements and the fiber content.
