东华大学硕士学位论文摘 东华大学硕士学位论文 摘 要 万方数据 万方数据 学处理达到复合材料增强织物要求。并对其组织结构和力学性能进行 测试。(2)复合材料试样制备。以热固性树脂-不饱和聚酯树脂为基体， 通过手糊成型法将其与废旧毛巾织物复合成型，探讨成型工艺及复合 材料质量控制，并计算制备获得试样的纤维体积含量。(3)复合材料试 样的拉伸性能研究。本文分别测试三种完整织物和三种拼接织物增强 复合材料的经、纬向拉伸性能，并对比分析其拉伸载荷-伸长曲线、 比强度和比模量及拉伸破坏模式等拉伸性能参数，研究增强织物的不 同和增强织物的拼接处理对试样拉伸性能的影响。(4)复合材料试样 的弯曲性能研究。研究方法与拉伸性能的研究相似。 结果表明：毛巾织物结构松软、毛圈丰满，能与不饱和聚酯树脂 进行很好的浸润复合；以手糊成型法制备毛巾/不饱和聚酯树脂复合 材料，能获得成型良好、结构均匀无气泡的试样；通过拉伸和弯曲性 能测试，可知试样具有较优的拉伸和弯曲性能，且拉伸破坏为脆性破 坏；毛巾的拼接处理，使得试样的弯曲破坏形式由脆性破坏变为韧性 破坏，并使试样的拉伸性能和弯曲性能都出现大幅度下降；增强织物 毛圈组织不同对拉伸性能无明显影响，但对弯曲性能有影响。 本文的研究工作，为以后废旧毛巾的复合材料回收利用法及实际 应用提供了一定的参考数据，具有一定的指导意义。 关键字：废旧毛巾；复合材料；回收利用；拉伸性能；弯曲性能 II 东华大学硕士学位论文AB 东华大学硕士学位论文 ABSTRACT STUDY ON THE FABRICATION AND THE MECHANICAL PROPERTIES OF WASTER TOWEL REINFORCED THERMOSETTING COMPOSITES ABSTRACT With the declining of textile materials and constantly expanding applications of textile products and the lifecycle of textile products is greatly shorten, a lot of good fabrics and clothing are discarded like garbage in our planet. Recycling of these waster textiles has become the key effective solution. Towels are the most common fabric of daily life, whether is in family, hotel, barber shops and so on. The use number of towels is huge and the use requirement of healthy towels is updated once three months, thus the number of waste towels is enormous. This paper takes waste towels as the research object, committed to seeking a waste towel recycling method. The recycling method of existing waste textile is in accordance with the waste textiles - renewable fiber - products recycling process technology, this processing line has many problems, such as it is a long process, the production cost is high, and involving more mechanical processing, damaging the performance of the regenerated fiber. Therefore, this paper use the hand lay-up molding composite material processing method to process waste towel, in order to shorten the process flow, reduce processing costs and reduce the performance of towel damage. Most towels use
