【摘要】 本文对纤维复合材料圆管的扭转剪切模量和弯曲剪切模量进行理论分析证明两者是不同的。并用圆管扭转试验测出扭转剪切模量,用GB1456三点外伸弯曲方法测出圆管弯曲剪切模量,结果与理论分析符合。有45°纤维缠绕的纤维复合材料圆管的扭转剪切模量比弯曲剪切模量大。更多还原

【Abstract】 The paper analyzes and compares the torsional shear modulus with flexural shear modulus of fibre composite pipe. These two mentioned moduli are different because of the anisotropy of composite. The torsional shear modulus is tested by pipe torsional test and flexural shear modulus tested by flexural method according to GB1456. The data from tests are very much similar to theory.! At the same time we get the result that the torsional shear modulus is greater than the flexural shear modulus with the pipe produced by 45°winding.更多还原
