二维/三维玄武岩搭接织物增强复合材料接合性能研究

Joint Properties of 2D/3D Basalt Fabric Reinforced Composites

研究了二维和三维玄武岩搭接织物增强复合材料接合处的性能。这种搭接复合材料是在三维正交织机上,通过改变织造方法和工艺,设计织造了单面阶梯状和双面阶梯状的三维玄武岩织物。设计了两种搭接方式,将玄武岩二维织物搭接到三维织物的阶梯处,并选取四种搭接长度,经过组合分别用真空辅助树脂转移成型技术做成织物增强复合材料。对材料的拉伸和弯曲的力学性能进行了测试,结果表明,双面搭接方法都比单面搭接方法更为有效,对提高二维和三维玄武岩织物增强复合材料搭接接合处的拉伸和弯曲性能更为有益。

The joint properties of 2D and 3D basalt fiber reinforced composites were investigated in this paper.The reinforcement of the joint composites was fabricated on the 3D orthogonal weaving machine.The single and double ladder 3D basalt fabric were both designed and woven by adjusting the weaving method.Two types of lap methods of single-face lap and double-face lap were applied in the joint processing,and four lap lengths were chosen.The final composites were obtained by using vaccum assistant resin transfer molding technology.The tensile and bending properties of the two types of lap composites were compared respectively.The results showed that the double-face lap composites had better mechanical properties than the single-face ones.
