Abstract

In this paper, ‎morphological, physico-chemical and thermal properties investigations‎ are carried out for a ‎novel ‎composite material reinforced by Washingtonia Filifera (WF) palm fibers using a 20 weight (wt) % loading rate. The experimental analysis by Scanning Electron Microscopy (SEM) shows the longitudinal roughness of the surface, which plays a very important role in the adhesion between the WF fibers and the High Density ‎PolyethylenE (HDPE) resin. FTIR tests of the composite (WF 20%/ HDPE) represent out of plane vibrations involving ring and CH2 symmetric bending in cellulose chain.‎ Thermogravimetric analysis (TGA) and Derivative thermogravimetric ‎(DTG) thermal analysis show a thermal stability at 210°C, 2.5% residual mass ‎and 745 °C maximum ‎temperature. X-Ray Diffraction (XRD) analysis shows that the ‎crystallinity index is 59.2%, with a size of ‎‎23 nm. Using tensile tests, a Young modulus of 858.6 MPa, ‎17% elongation and a maximum stress of 15 MPa ‎are found. The obtained characteristics of WF reinforced composite are better than those of Bamboo reinforced composites which has been proven to have characteristics superior to those of standard particleboard and medium density fiberboard used mainly in the construction industry.

一种新型植物纤维增强热塑性复合材料的物理化学和热力学分析及表征

本文研究了一种以WF棕榈纤维增强的新型复合材料的形态、物理化学和热性能，加载率为20%。扫描电镜(SEM)实验分析表明，WF纤维表面的纵向粗糙度对其与高密度聚乙烯(HDPE)树脂的粘附起着非常重要的作用。复合材料(WF 20%/ HDPE)的FTIR测试显示纤维素链中的环和CH2对称弯曲引起的平面外振动。热重分析(TGA)和导数热重分析(DTG)表明，在210°C、2.5%残余质量和745°C最高温度下，热稳定性良好。x射线衍射(XRD)分析表明，该晶体结晶度指数为59.2%，晶粒尺寸为23 nm。拉伸试验结果表明，合金的杨氏模量为858.6 MPa，延伸率为17%，最大应力为15 MPa。所得的WF增强复合材料的性能优于竹材增强复合材料，竹材增强复合材料的性能优于主要用于建筑行业的标准刨花板和中密度纤维板。

期刊介绍： "International Journal of Engineering Research in Africa" is a peer-reviewed journal which is devoted to the publication of original scientific articles on research and development of engineering systems carried out in Africa and worldwide. We publish stand-alone papers by individual authors. The articles should be related to theoretical research or be based on practical study. Articles which are not from Africa should have the potential of contributing to its progress and development.
