Adhesive wear behaviour of surface modified bamboo filler reinforced polymer composite under different contact condition

ABSTRACT

An experimental study has been conducted to evaluate the adhesive wear behavior of bamboo filler-reinforced polymer composite. Bamboo has the significant attention of investigators due to its benefits over human-made fibers. The bamboo fillers’ surface is treated by the alkali treatment process and the composite is prepared with a variation of micro bamboo particle support (i.e. 0, 2.5, 5, 7.5, 10, and 12.5%). The study of tribological characterization is explored for dry, wet, and heated sliding contact state using the pin-on-disk tribomachine counter to a stainless steel disc. Modified bamboo filler composite exhibited better interaction between filler and matrix, which improve the wear resistance capacity of the composite. From the experimental result it is found that specific wear rate and coefficient of friction is lesser in wet condition compared to dry and heated state conditions. Moreover, lower filler content offered enhanced wear performance related to the higher filler content composite. In case of dry sliding contact, debonding and plastic deformation are witnessed on the composite surfaces. However, the worn regions are minimal under wet state condition. Further, in case of the heated state, a thin layer created on the exterior of composite which safeguards the surface from further worn.

摘要

对竹材填料增强聚合物复合材料的粘着磨损性能进行了实验研究. 由于竹子比人造纤维更具优势, 因此受到了研究人员的高度关注. 通过碱处理工艺对竹填料表面进行处理, 并使用不同的微竹颗粒载体 (即0、2.5、5、7.5、10和12.5%) 制备复合材料. 利用针盘式摩擦机计数器对不锈钢圆盘进行了干、湿、热滑动接触状态的摩擦学特性研究. 改性后的竹基复合填料与基体之间表现出更好的相互作用, 提高了复合材料的耐磨性. 从实验结果可以看出, 与干燥和加热状态相比, 湿状态下的比磨损率和摩擦系数较小. 此外, 较低的填料含量提供了与较高填料含量的复合材料相关的增强磨损性能. 在干滑动接触的情况下, 复合材料表面会出现脱粘和塑性变形. 然而, 在潮湿状态下, 磨损区域最小. 此外, 在加热状态下, 在复合材料表面形成一层薄薄的保护层, 防止表面进一步磨损.
