增强纤维的抗张强度是制造复合材料时所关心的最重要的物理性能指标之一。大家的叫法不尽统一,有人称之为抗拉强度,也有人称为扯断强度或断裂强度。虽然叫法不同,但它们所表示的物理概念是相同的,即纤维在拉力作用下抵抗破坏的能力。可用极限强度来表示。表示纤维抗张强度的单位通常有三种:千米、克/袋和 Reinforcing the tensile strength of the fiber is one of the most important physical properties that are of interest in the manufacture of composite materials. Everyone’s name is not uniform, some call it tensile strength, but also some people call the tensile strength or breaking strength. Although called differently, the physical concept they represent is the same, that is, the ability of the fiber to withstand damage under tension. Available ultimate strength to represent. There are usually three types of units that represent the tensile strength of a fiber: kilometer, gram / bag, and
