Abstract
In view of the shortcomings of low measurement accuracy,high cost and low efficiency in the current testing method for shear strength of fiber reinforced composite materials,this paper proposes an improved three-point bending shear strength measurement scheme.By pasting reinforcement plates on the surface of the specimen,the ratio of maximum shear stress to normal stress of the composite material is adjusted to prioritize shear failure of the composite material.The improvement scheme proposed in this article was experimentally tested from both experi-mental verification and theoretical analysis.The test results show that the maximum error of the optimized scheme for measuring the shear strength of composite materials proposed in this article is 1.56,and the minimum error is 0.30.The error is within an acceptable range,which can provide reference for related work.关键词
