摘要
纺织复合材料具有力学性能优良、造价低廉且易于形成各种复杂形状的特点。涤纶因自身结构导致其界面与树脂的黏结能力差,给涤纶复合材料的研制带来困难。采用等离子处理对涤纶进行改性,研究了放电功率、放电时间及放电压强对涤纶处理效果的影响。结果表明:涤纶力学性能随等离子处理时放电时间、放电功率、放电压强的增大而下降。研究了等离子体改性前后涤纶与聚氨酯弹性体界面的黏结牢度,结果表明改性后的涤纶与聚氨酯弹性体界面的黏结牢度有很大提高。放电功率为80 W,放电时间为200s,放电压强为25Pa时,既能得到较好的黏结牢度,又能保持涤纶较好的力学性能。
Textile composites are characterized by excellent mechanical properties, low cost and easy implementation of complex shapes. Due to the structure, the polyester has poor bonding ability between the interface and the resin, which makes it difficult to develop the polyester composite material. The polyester was modified by plasma treatment. The effects of discharge power, discharge time and discharge voltage on the polyester treatment were studied. The results showed that the mechanical properties of polyester decreased with the increase of discharge time, discharge power and discharge voltage during plasma treatment. The adhesion fastness of polyester to polyurethane elastomer interface before and after plasma modification was studied. The results showed that the bonding strength between modified polyester and polyurethane elastomer interface was greatly improved. The treatment process has a discharge power of 80 W, a discharge time of 200 s, and a discharge voltage of 25 Pa, polyester can obtain good adhesion fastness and maintain good mechanical properties of polyester.
