The effect of different metal and fibre strengtheners on the fracture resistance of polymethylmethacrylate was tested. Different types of commonly used metal wire and glass fibre, as well as carbon and aramid fibres, were used as strengtheners in test specimens. There were 21 groups, and each group contained 12 test specimens. Each metal strengthener had a beneficial effect on the fracture resistance of the polymethylmethacrylate (P less than 0.001-0.01). Some fibres, which were silanized for better adhesion, also had strengthening properties.
测试了不同金属和纤维增强剂对聚甲基丙烯酸甲酯抗断裂性的影响。在测试样本中，使用了不同类型的常用金属丝、玻璃纤维以及碳纤维和芳纶纤维作为增强剂。共有21组，每组包含12个测试样本。每种金属增强剂对聚甲基丙烯酸甲酯的抗断裂性都有有益影响（P小于0.001 - 0.01）。一些经过硅烷化处理以获得更好附着力的纤维也具有增强性能。
