Abstract

Epoxy methacrylate of bisphenol-C-jute/treated jute and their sandwich composites of white coir, brown coir, wild almond, bamboo, betel nut, and palmyra were prepared by a compression molding technique under 5MPa pressure and at room temperature for three h. The neat sample showed almost double tensile strength than its jute composite, while it is comparable for treated jute. The composites revealed substantially improved flexural strength compared to neat. The neat, jute/treated jute and their sandwich composites indicated good impact strength, pretty good Barcol hardness, and fairly good electric strength. The neat sample showed excellent volume resistivity, while jute/treated jute and their sandwich composites revealed reasonably good volume resistivity. The composites showed high water ingress tendency, excellent hydrolytic stability, and different diffusivity in different environments at 30oC. Water ingress trend was observed the same for all the composites in different environments, and it is H2SO4 > HCl >NaOH >H2O>NaCl. The sandwich composites may find their applications as low-cost housing and insulating materials and also for marine vessels.

双酚- c -黄麻/处理过的黄麻-天然纤维夹层复合材料可持续环氧甲基丙烯酸酯的制备及性能比较:第1部分

在5MPa压力和室温条件下，采用压缩成型技术制备了双酚- c -黄麻/处理黄麻环氧甲基丙烯酸酯及其夹心复合材料(白椰、棕椰、野杏仁、竹、槟榔、棕榈)的抗拉强度几乎是处理黄麻复合材料的两倍，与处理黄麻的抗拉强度相当。与纯复合材料相比，复合材料的抗弯强度得到了显著提高。纯黄麻/处理过的黄麻及其夹层复合材料具有良好的冲击强度、巴氏硬度和较好的电强度。整洁样品具有优异的体积电阻率，而黄麻/处理过的黄麻及其夹层复合材料具有较好的体积电阻率。复合材料在30℃不同环境下具有较高的进水倾向、优异的水解稳定性和不同的扩散系数。所有复合材料在不同环境下的进水趋势相同，为H2SO4 >HCl >NaOH >H2O>NaCl。夹层复合材料可作为低成本的房屋和绝缘材料，也可用于船舶。

期刊介绍： Journal of Polymer Materials-An International Journal is published quarterly (4 issues per year), which covers broadly most of the important and fundamental areas of Polymer Science and Technology. It reports reviews on current topics and original research results on synthesis of monomers and polymers, polymer analysis, characterization and testing, properties of polymers, structure-property relation, polymer processing and fabrication, and polymer applications. Research and development activities on functional polymers, polymer blends and alloys, composites and nanocomposites, paints and surface coatings, rubbers and elastomeric materials, and adhesives are also published.
