Abstract

Solid particle erosion behavior of short date palm leaf (DPL) fiber reinforced polyvinyl alcohol (PVA) composite has been studied using silica sand particles (200 ± 50 μm) as an erodent at different impingement angles (15–90°) and impact velocities (48–109 m/s). The influence of fiber content (wt% of DPL fiber) on erosion rate of PVA/DPL composite has also been investigated. The neat PVA shows maximum erosion rate at 30° impingement angle whereas PVA/DPL composites exhibit maximum erosion rate at 45° impingement angle irrespective of fiber loading showing semiductile behavior. The erosion efficiency of PVA and its composites varies from 0.735 to 16.289% for different impact velocities studied. The eroded surfaces were observed under scanning electron microscope (SEM) to understand the erosion mechanism.
枣椰叶纤维增强聚乙烯醇复合材料的固体颗粒侵蚀性能
研究了短枣棕榈叶(DPL)纤维增强聚乙烯醇(PVA)复合材料在不同冲击角(15 ~ 90°)和冲击速度(48 ~ 109 m/s)下的固体颗粒侵蚀行为。研究了纤维含量(DPL纤维wt%)对PVA/DPL复合材料侵蚀速率的影响。纯聚乙烯醇复合材料在30°冲击角时的冲蚀速率最大,而PVA/DPL复合材料在45°冲击角时的冲蚀速率最大,与纤维载荷无关。不同冲击速度下,PVA及其复合材料的冲蚀效率在0.735% ~ 16.289%之间。在扫描电镜下观察侵蚀面,了解侵蚀机理。
