虽然纤维增强塑料复合材料在很多领域,如,飞行器工业,汽车工业,造船工业和房屋建造等方面得到了广泛的应用,但是由于其破坏行为的复杂性,使其应用和设计受到了限制。含孔复合材料的性能已经成为研究的一个热点。本研究通过引进针刺工艺以提高含孔玻璃纤维增强塑料复合材料的性能。该工艺不仅降低了层间纤维的距离同时也引入了垂直于板材的刺入纤维。本文使用直径为10mm的钻头来制备复合材料上的圆孔。文中通过对比普通玻璃纤维毡复合材料和经过针刺后玻璃纤维毡复合材料的性能,分析了破坏行为和拉伸性能的差异性,并通过利用MSC-Marc的有限元分析对比了两种材料对于圆孔的敏感性。研究表明,经过针刺后制成的玻璃纤维毡复合材料对于圆孔的敏感性相对较低。
Although fiber-reinforced plastic composites have been widely used in many fields, such as aircraft industry, automobile industry, shipbuilding industry and house construction, their application and design are limited due to the complexity of their sabotage behavior. The properties of porous composites have become a hot spot of research. In this study, acupuncture was introduced to improve the performance of glass fiber reinforced plastic composites. The process not only reduces the distance between the layers of fibers but also introduces punctured fibers perpendicular to the sheet. In this paper, a drill with a diameter of 10mm was used to prepare circular holes in the composite. In this paper, by comparing the performance of ordinary glass fiber mat composite and glass fiber mat composite after needle punching, the difference between failure behavior and tensile performance is analyzed. By comparing the two materials with MSC-Marc, The sensitivity of the hole. Studies have shown that glass fiber mat composites made after needling are relatively less sensitive to circular holes.
