不同测试条件对碳纤维复丝部分力学性能的影响

Different test conditions' effects on mechanical property of carbon fiber multifilament

就国内某企业生产的3K普通高强碳纤维,用相同的制样方法制备出碳纤维样品,在同一材料实验机上,用不同的测试条件对碳纤维力学性能进行测试,得出不同测试条件下碳纤维的拉伸强度、弹性模量、断裂伸长率等主要力学性能表征值。

The test of the 3K carbon fiber made by an enterprise in China was introduced. The carbon fiber samples used in the test were obtained by using the same manufacturing method. The mechanical performance of the carbon fiber was tested with different test conditions on the same machine to obtain the tensile strength, modulus and breaking elonga- tion rate capability value.
