The Molding Technology of Manufacturing Waste Blend Fiber Composites by Mixed Hotpressing

Article Preview

Abstract:

For the waste polyester/cotton/hemp blend fiber of largest abandoned number,this paper designed and optimized the molding technology of manufacturing waste blend waste composites by mixed hotpressing,and analyzed the mechanical properties of composites. Through the orthogonality experiment,the optimum conditions were given as follows:the ratio of waste blend fabrics 1:1,the Concentration of PP 60%,the temperature of hotpressing 185°C，the hotpressing pressure 12Mpa, the hotpressing time 5min. Under above conditions,the composites had the density 0.9326g/cm2,the tensile strength 45.37Mpa, the bending strength 48.31Mpa and the energy absorption of impact 15.32 KJ/m2.
