标准摘要
[中文适用范围]： 本文件规定了适用于作为混凝土基材上的外部粘合增强材料的单向碳纤维增强聚合物（CFRP）带的测试方法。 本文件适用于以下CFRP条： ——由碳纤维和热固性树脂组成； ——采用拉挤成型方法制造； ——碳纤维含量较高，如超过60%； - 厚度在 3 毫米以内。 另外，用于确定拉伸性能的测试件是从CFRP条沿CFRP条轴线切下的，并且在两端具有粘结锚固块。 [外文原描述]： This document specifies test methods applicable to unidirectional carbon fibre-reinforced polymer (CFRP) strips as external-bonded reinforcements on the concrete substrate. This document is applicable for the CFRP strips that: — consist of carbon fibre and thermoset resin; — are manufactured by pultrusion method; — have a higher carbon fibre fraction such as over 60 %; and — have a thickness within 3 mm. Also, the test pieces for determining tensile properties are cut down from CFRP strips along the CFRP strips axis, and have bonded anchorage block at the both ends.
