实验参数对高性能石英纤维摩擦性能的影响
|
摘要
针对立体织物织造过程中高强高模纤维束间相互摩擦而导致织物性能下降的问题,以石英纤维为例,设计了一种用于测试纤维束间摩擦性能的摩擦磨损试验机夹具,使纤维束或单根纤维能够以相互正交或一定角度相接触,在纤维尺度上研究了摩擦角度、摩擦频率和法向载荷对纤维束间摩擦性能的影响。结果表明:3种实验参数对纤维束表面的磨损程度不同;摩擦角度为70°时的摩擦因数是90°时的1.2倍,即摩擦角度越小,磨损程度越大;在一定范围内,摩擦频率和法向载荷对摩擦因数没有影响;在立体织物织造过程中,应尽可能减少纤维束间倾斜接触,从而降低织物性能下降,还可在一定范围内提高织造频率和法向载荷,提高生产效率。
In order to solve the problem that the friction between high strength and high modulus tows of three-dimensional fabrics in weaving process reduces the properties of fabrics,taking quartz fiber as an example,a fixture for friction and wear testing machine for testing the friction between tows was designed.With this machine,the tows or single fibers could be in contact with each other at vertical or certain angles. The influence of friction angle,friction frequency and load on the frictional properties of tows on fiber scale was studied. The results show that the three experimental parameters have different degrees of friction and wear on the surface of the tows. The friction coefficient at a friction angle of 70° is 1. 2 times of that at 90°,and the smaller the friction angle,the greater the wear degree. Friction frequency and load have no effect on friction coefficient within a certain range. In the weaving process of 3-D fabrics,the inclined contact between the tows should be reduced as much as possible to decrease the fabric performance degradation,and the weaving frequency and load can be increased within a certain range to improve the production efficiency.
