基于手工制样的碳纤维复丝拉伸性能测试方法

摘要

Tensile property is an important index in the evaluation of performance of carbon fiber.The dipping time, curing time,selection of reinforcement,glue laying method and tensile speed in tensile test are tested for manual sample.It was determined the dipping time and curing time for manual sample were 3 min respectively.Kraft paper was used as reinforcing sheet.The tensile speed was 15 mm /min in the tensile test. The tiling glue laying method could improve the reliability and accuracy of the test.%拉伸性能是碳纤维性能中一个重要的评价指标，对手工制样的试样浸胶时间、固化时间、加强片的选择、胶水铺设方法及拉伸测试中拉伸速度进行试验，确定手工制样中试样浸胶时间为3 min，固化时间为3 min，加强片选用牛皮纸，拉伸测试中拉伸速度为15 mm ／min，采用平铺胶水铺设方法，可有效提高拉伸测试的可靠性和准确性。
