Preparation method of composite material compression performance test piece

The invention relates to a preparation method of a composite material compression performance test piece. The preparation method comprises the following steps: 1, cleaning the surfaces of a compression test plate and a reinforcing sheet by utilizing a solvent; 2, pre-burying an adhesive easy-to-demold material on the working section of the compression test plate according to the requirements of the compression performance test piece; 3, pasting a structural adhesive film on the non-working section of the compression test plate; 4, assembling the compression test plates obtained in the step 2 and the step 3 with the reinforcing sheets obtained in the step 1 to form an assembly; 5, packaging the assembly obtained in the step 4 on a tool by using a vacuum bag, and feeding the assembly into atank for cementing; 6, after can discharging and demolding, machining a working section at the position where the materials capable of being pasted and easily demolded are pre-buried, and the materials capable of being pasted
