ABSTRACT
Composites were fabricated from Ramie cellulose microfibrils (RCMF) with cassava starch as matrix and glycerol as a plasticizer. Different composites were fabricated with microfibrils loadings of 0, 2, 4, 8, and 10 wt%. The Particle Size Analyzer results show the average size of RCMF as 1.573 μm. The addition of RCMF considerably influenced the physical, crystalline, thermal, and tensile properties of composites. The addition of RCMF enhanced the crystallinity index (CI) from 32% to 36.67%. Thermogravimetric analysis and tensile test results showed improvement in thermal stability and tensile strength of composite up to 6 wt% microfibrils addition.
摘要
以Ramie纤维素微纤维（RCMF）为原料，以木薯淀粉为基质，甘油为增塑剂，制备了复合材料。用微纤维负载量分别为0、2、4, 8和10WT%制备不同的复合材料。粒度分析结果表明，Ramie纤维素微纤维的平均粒径为1.573μm。苎麻纤维素微纤维的加入显著影响了复合材料的物理、结晶、热、拉伸性能。苎麻纤维素微纤维的加入使结晶度指数（CI）从32%提高到36.67%。热重分析和拉伸试验结果表明，复合材料的热稳定性和拉伸强度提高到6重量%的微纤维。
