摘要
近年来,人们越来越需要用非常规天然纤维合成混合复合材料。考虑到这一需求,在当前的研究中,通过在树脂中添加不同量的仙人球(最高达 20 wt%,增量为 5 wt%)来增强木苹果壳粉和椰子壳粉,从而制成了混合复合材料,并对其机械和摩擦学性能进行了评估。这些复合材料的密度与添加剂的用量直接相关。与其他配方相比,含有 10 wt% 的仙人球以及 15 wt% 的木苹果壳粉和椰子壳粉的复合材料具有更强的拉伸和弯曲性能。考虑到加载因素、移动距离和速度,在室温下使用针盘装置进行了干滑动磨损测试。由 10 wt% 的仙人球组成的混合复合材料在承受 10 N(1.02 kgf)的正常载荷,并以 1.5 m s-1(90 m min-1)的滑动速度在 500 m 的距离上进行测试时,与所有其他复合材料变体相比,表现出更优异的耐磨性。
Influence of suspended cenospheres on the mechanical characteristics and wear loss of natural fiber-reinforced hybrid composites: implications for biomedical applications and sustainable material management
The need for non-conventional natural fibres for synthesis of hybrid composites has gained momentum in the recent past. Taking into consideration this need, in the current study, hybrid composites were fabricated by reinforcing wood apple shell powder and coconut shell powder, in the resin with varying amounts of cenospheres (up to 20 wt% in increments of 5 wt%) to evaluate their mechanical and tribological properties. The densities of these composites were directly correlated with the quantity of additives utilized. Enhanced tensile and flexural properties were noted in composites containing 10 wt% cenospheres, along with 15 wt% wood apple shell powder and coconut shell powder, compared to other formulations. Dry sliding wear tests were performed at room temperature using a pin-on-disc apparatus, considering loading factors, travel distance, and speed. A hybrid composite consisting of 10 wt% cenospheres, subjected to a normal load of 10 N (1.02 kgf), and tested at a sliding speed of 1.5 m s−1 (90 m min−1) over a distance of 500 m, exhibited superior wear resistance compared to all other composite variations.
