The used tyre rubber, scrap ceramic tiles and wood dust are largely dumped into landfills, which create environmental pollution to the surrounding. The recycling of tyre rubber is very limited, but it has good property to absorb the impact energy. Hence, these materials are used to prepare the composite in the present work. Composite materials were prepared by the resin transfer moulding method with different weight percentage of particles. The tensile, flexural and impact strength of composite specimens were compared with other combination of composites and also with the neat resin sample specimen. The tensile and flexural strength of composites were decreased with the addition of the rubber. But, the rubber particle with the ceramic in the resin matrix increases the impact strength of composite by 45.91% when compared with the neat resin sample. The addition of rubber enhances the impact strength of composite materials with all the combination of particles. The better distribution and good interfacial adhesion of particles with a resin matrix along the fractured surface were observed by the scanning electron microscope. And also, the nature of failure was identified by morphological studies.

陶瓷和木材混合使用的轮胎橡胶在冲击能量吸收方面的应用

废旧的轮胎橡胶,废旧瓷砖和木屑大量倒入垃圾填埋场,对周围环境造成环境污染。轮胎橡胶的回收非常有限,但是具有吸收冲击能量的良好性能。因此,在目前的工作中,这些材料被用于制备复合材料。通过树脂传递模塑法制备具有不同重量百分比的颗粒的复合材料。将复合材料样品的拉伸,弯曲和冲击强度与复合材料的其他组合以及纯树脂样品样品进行了比较。添加橡胶会降低复合材料的拉伸强度和弯曲强度。但是,与纯树脂样品相比,树脂基体中具有陶瓷的橡胶颗粒将复合材料的冲击强度提高了45.91%。橡胶的添加增强了颗粒所有组合对复合材料的冲击强度。通过扫描电子显微镜观察到沿断裂表面的颗粒与树脂基质的更好的分布和良好的界面粘附。并且,通过形态学研究确定了失效的性质。
