【摘要】 采用自行研制的摆锤式冲击拉伸试验机对玻璃纤维、芳纶纤维、超高分子量聚乙烯纤维和PBO纤维丝束及其混杂丝束进行了冲击拉伸试验。得到混杂纤维丝束断裂吸能和断裂强度随纤维混杂比变化的规律更多还原

【Abstract】 This paper deals with an investigation of low velocity tensile impact behavior of glass fiber,Twaron fiber, UHMMPE fiber and PBO fiber bundle rspectively and their hybrid fiber bundles. The experiment is conducted on a self designed digital Charpy impact tester. The variation principle of fracture strength and energy absorption of hybrid fiber bundle with different hybrid ratio is obtained.更多还原
