The Technology of Manufacturing Waste Fiber and Flame Retardant TPU Composites by Mixed Hotpressing

Abstract:

For the large number of waste cotton/hemp blend fiber, the molding technology of manufacturing waste blend composites was designed and optimized by mixed hot pressing in this paper, and the mechanical properties of composites were analyzed. Through the orthogonal experiment, the optimum conditions were given as follows: cotton, hemp, TPU fiber composite: the ratio of waste blending fiber 40:60,hotpressing temperature180°C，the concentration of TPU 60%,hotpressing pressure 10Mpa,.The density of composite made by this condition was1.220 g/cm2. Under above conditions, the composites had the density 1.220g/cm2, the tensile strength32.30Mpa, the bending strength 28.51Mpa and the energy absorption of impact 37.25 KJ/m2, heat transfer coefficient 0.0018W/M•K.
