Abstract

Abstract

In order to improve the anchoring performance and tensile properties of carbon fibre reinforced plastics (CFRP) plates, the influence of failure phenomenon, types of anchoring resin, types of matrix resin, and fiber volume content on the tensile properties of carbon fiber plates were studied by static load test. The results showed that explosive failure was the most reasonable failure mode, which could best reflect the real performance of CFRP plates, and the tensile strength was greater than that of brittle fracture. The greater the shear strength of the anchoring resin, the more conducive to anchoring, and it was recommended to use epoxy film for anchoring; the viscosity of the matrix resin had a great influence on the tensile properties; for 1.2 mm CFRP plates, with the increase of fiber volume content, the tensile strength first increased and then decreased, and the elastic modulus gradually increased, and the optimal fit ratio was 66%.
