Abstract: In order to improve the interlayer performance of glass fiber/ethyl hexyl ester(GF/EHP) materials,chlorinated polyvinyl chloride(PAM), poly butyl glycol terephthalate(PBT), polyamide(PA66), and ethylene/vinyl acetate(EVA) are added respectively to improve the interlayer performance of glass fiber/ethyl hexyl ester(GF/EHP) material prepared by the VARI process, and the tensile, flexural and interlaminar fracture toughness were investigated by experimental tests. The results show that GF/EHP materials have a larger thickness, lower density,and higher resin content after weaving, and the GF/EHP materials obtained have a higher porosity. With the addition of woven cloth, a larger thickness is obtained, the fiber volume ratio is reduced, and the fiber is more likely to cracking and debonding from the matrix. After adding the fabric between the layers, the bending strength decreases slightly. In the fracture test of GF/EHP material after EVA was added, no brittle fracture occurred when the fiber was extracted, which improves the binding property between the fiber and the matrix, and significantly improves the anti-crack growth ability of GF/EHP material.
