摘要: 研究了T700碳纤维/玻璃纤维、T700碳纤维/玄武岩纤维不同纤维配比混杂材料的层合板拉伸性能。结果表明,混杂纤维层合板的拉伸性能随着碳纤维含量提高而提高;高断裂位移的纤维可以提高混杂纤维复合材料的断裂伸长率。复合材料模量混杂公式得到的理论值与实际测量值比较接近;加入玻璃纤维或玄武岩纤维可以提高复合材料的韧性,同时节省成本。

Abstract: Tensile performances of the laminated plates made from T700 Carbon Fiber/Glass Fiber and T700 Carbon Fiber/Basalt Fiber with different ratios were studied. The study found that tensile performance of hybrid fiber composite laminated plates was proportional to the content of the carbon fiber. High fracture displacement of fiber could improve the elongation at break of hybrid fiber composite materials. The theoretical value from mixed composite modulus formula was close to the actual measure value, and the reliability of new hybrid fiber formula was verified. The toughness of pure carbon fiber composite was improved by adding glass fiber or basalt fiber, and the costs would be saved at the same time.
