摘要

以双酚- c -黄麻/处理过的黄麻-香蕉/花生/蔗糖/菠萝叶/稻壳/麦壳为复合材料，在5 MPa压力下室温下压缩成型3 h，制备了甲基丙烯酸环氧树脂复合材料。碱处理后的黄麻-天然纤维复合材料的力学性能明显优于未经处理的黄麻-天然纤维复合材料，这是由于黄麻纤维的表面改性。两种类型的夹层复合材料均表现出较高的吸水倾向，对酸、碱和盐溶液具有良好的水解稳定性，并且在30℃下具有较长的平衡时间。碱处理的夹层复合材料吸水倾向明显低于未处理的夹层复合材料。观测到的吸水趋势为H2SO4 >HCl >NaOH >H2O>NaCl。

Fabrication and Comparative Properties of Sustainable Epoxy Methacrylate of Bisphenol-C-Jute/Treated Jute- Natural Fibers Sandwich Composites: Part-2

Compression-molded epoxy methacrylate of bisphenol-C-jute/treated jute-banana/groundnut/ cane sugar/pineapple leaf/rice husk/wheat husk sandwich composites were fabricated under 5 MPa pressure at room temperature for 3 h. Alkali treated jute-natural fiber sandwich composites displayed considerably improved mechanical properties over untreated jute-natural fiber sandwich composites due to surface modification of the jute fibers. Both types of sandwich composites showed high water uptake tendency, excellent hydrolytic stability against acids, alkali, and salt solutions, and also a longer equilibrium time at 30oC. Alkali treated sandwich composites revealed a considerably lower water uptake tendency than untreated sandwich composites. Observed water uptake trend is H2SO4 > HCl >NaOH >H2O>NaCl.

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.
