摘要： An impact test fixture capable of applying preload on a composite laminate, which is composed of a base, a clamping mechanism and a loading mechanism, where the clamping mechanism is positioned on an upper surface of the base and fixedly connected to the base through a bolt, and the loading mechanism is installed at an end of the base. A composite laminate is placed in a rectangular groove of the base. A first wedge block and a second wedge block are positioned in a base sliding groove between a pressing block and a baffle plate, and inclined planes of the two wedge blocks are oppositely installed; the baffle plate is matched with the base through a first fixing bolt and a second fixing bolt, a loading bolt passes through a screw hole at a side end of the base and is matched with the first wedge block.
