ABSTRACT
Rotational molding is a powder processing technology widely used to manufacture hollow plastic products. It is a well-known process used for the manufacturing of large containers, water tanks, fuel tanks, refrigerated containers, etc. This study aimed at the incorporation of Tampico and Palmyra fibers as reinforcement in Linear Low-Density Polyethylene (LLDPE) tanks produced by the rotational molding process. The effect of fiber content on various properties like mechanical, morphological, and vibration damping characteristics of the composites were investigated. The fibers were initially treated with 5% NaOH solution for better reinforcing efficiency and to improve the degradation temperature. Thermo Gravimetry Analysis (TGA) reported that a sufficient increment in degradation temperature is achieved by NaOH treatment on fibers. The short fiber composites considered for the study have obtained better mechanical strength than long fiber reinforced LLDPE composites. The results proved that fiber length has less effect on the vibration damping characteristics of the composites, but the percentage of fiber content is a significant factor for improving the natural frequency of the composites.
摘要
旋转成型是一种广泛用于制造中空塑料制品的粉末加工技术. 这是一种众所周知的工艺, 用于制造大型容器, 水箱, 油箱, 冷藏容器等. 目前的工作旨在将坦皮科纤维和帕尔米拉纤维作为增强材料加入由旋转模塑工艺生产的线性低密度聚乙烯 (LLDPE) 罐中. 研究了纤维含量对复合材料力学, 形态和减振性能的影响. 纤维最初用5%氢氧化钠溶液处理, 以提高增强效率和降解温度. 热重分析 (TGA) 报告称, 通过对纤维进行NaOH处理, 可以充分提高降解温度. 研究中考虑的短纤维复合材料比长纤维增强LLDPE复合材料获得了更好的机械强度. 结果表明, 纤维长度对复合材料的减振性能影响较小, 但纤维含量是提高复合材料固有频率的重要因素.
