Experimental Study on Preparation and Mechanical Properties of CF Knitted Fabric Composites for Nut Lining

[摘要] To solve the problem of preparing composite screw nut lining, a preparation method of lining by the CF knitting stretch fabric was discussed. The effects of vacuum treatment and secondary reinforcement of chopped fiber on the mechanical properties of CF woven fabric and knitted fabric composite were studied. The results showed that the compressive strength of composites increased by 8.86% and 8.08% after vacuum treatment, and the impact strength increased by 15.55% and 9.43% respectively. The secondary reinforcing effect of chopped fibers was obvious, and the compressive strength increased by 9.91% and 22.52% respectively. The actual application showed the composite nut lining prepared by using the CF tubular knitted stretch fabric could better solve the defects of insufficient strength and partial peeling.
