纤维增强树脂基复合芯胶槽设计改进方案

Fiber Reinforced Resin Matrix Composite Core Rubber Groove Design Improvement Scheme

纤维增强树脂基复合芯中碳纤维丝体积含量高时,复合芯强度高而韧性差,玻璃纤维丝体积含量高时,复合芯强度低而韧性好,但在实际生产过程中,部分生产单位往往侧重于复合芯的强度而忽略复合芯的韧性,其实从施工角度考虑,复合芯的韧性是必须要首先保证的。在韧性满足要求的情况下,强度能不能保持是最关键的考核因素,特别是直径较大的复合芯,因其纤维含量较高,很容易导致复合芯中的纤维出现浸润不透的情况,恰恰这种现象对复合芯的强度损失是致命的。为了更好地解决这个问题,需要对胶槽结构重新进行设计和论证。

Fiber reinforced resin based carbon fiber composite core wire volume content is high, high strength and toughness is poor, glass fiber volume content is high, low strength and good toughness, but in the actual production process part of the production unit, often focusing on the composite core strength and ignore the composite core tough- ness, in fact, from the construction point of view, the toughness of the composite core is must first guarantee. In the condition of toughness, strength can not keep checking the most crucial factor, especially large diameter composite core, because of its high fiber content, can easily lead to infiltration impermeable case composite core in fiber, strength loss is precisely this phenomenon of the composite core is fatal, in order to better to solve this problem, the need to re design and demonstration of the glue groove structure.
