项目摘要

Conventional FRPs have some problems in the case of disposal. The combustion disposal discharges the carbon dioxide in the air because the resins of FRPs are made of fossil fuel. In the case of disposal in the ground, these FRPs remain semi-permanently without decomposing. Therefore, green composites are now developing and are studied as a material of less environmental burden. In this study, a pultrusion, an injection and a hot-press molding methods were developed for fabricating green composites composed of PLA (Poly lactic acid) or PBS (Poly Butylene Succinate) resin as a matrix and kenaf fibers as reinforcement. Their tensile strengths at the different temperatures were examined. These results were compared with each other. As a result, the following items were obtained as important fruits of this study.(1)The pultrusion method which could continuously fabricate green composites was demonstrated here.(2)The tensile strengths and Young's moduli of PLA/kenaf and PBS/kenaf composites were larger than those of both resins alone at the different temperatures. This result shows the reinforcement effect of PLA and PBS by kenaf fibers at the room and the higher temperatures.(3)Since the tension applied to the fiber bundles during the pultrusion molding, the tensile strength and Young's modulus with the pultrusion method were larger than those with other molding methods.(4) The heat resistance of the PBS/kenaf composite was higher than-that of PLA/kenaf composite.

传统的FRPS在处置方面存在一些问题。燃烧处理会排放空气中的二氧化碳，因为FRPS的树脂是由化石燃料制成的。如果处置在地下，这些FRPS将保持半永久性，不会分解。因此，绿色复合材料正在发展，并被作为一种环境负担较小的材料进行研究。本研究以聚乳酸或聚丁二酸丁二醇酯树脂为基材，红麻纤维为增强体，采用拉挤、注射和热压成型三种方法制备绿色复合材料。测试了它们在不同温度下的拉伸强度。并对这些结果进行了比较。(2)在不同温度下，聚乳酸/红麻和PBS/红麻复合材料的拉伸强度和杨氏模数均大于两种树脂单独的拉伸强度和杨氏模数。结果表明，在室温和较高温度下，红麻纤维对聚乳酸和硫化铅纤维均有增强作用。(3)在拉伸挤出成型过程中，纤维束受到的拉力较大，拉伸强度和杨氏模量均大于其他成型方法。(4)PBS/红麻复合材料的耐热性高于聚乳酸/红麻复合材料。
