摘要

摘要: 为了改善碳纤维复合材料板的锚固性能，同时为了提高碳纤维复合材料板的拉伸性能，通过静载试验研究了碳纤维复合材料板的破坏现象、锚固树脂的种类、基体树脂的种类、纤维体积含量对拉伸性能的影响。结果表明：爆炸式破坏是最合理的破坏模式，最能反映碳纤维复合材料板的拉伸性能，拉伸强度大于脆性断裂的强度；锚固树脂剪切强度越大，越利于锚固，建议采用环氧胶膜进行锚固；基体树脂的黏性，对拉伸性能影响较大；对于1.2 mm的碳纤维板，随着纤维体积含量的增加，拉伸强度先增加后降低，弹性模量逐步增加，本次最优配合比为66%。

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%.
