Waste Blended Fiber Composite Material And Its Mechanical Properties

The world textile fiber consumption rapidly increasing year by year, How to make betteruse of recycling waste materials, textile fibers has become a subject of researchers trying toexplore. The paper studies the two production ways of composite materials (blendingplastication(1)Test and analysis the mechanical properties of compound plates made by blendingplastication mode, and determine the factors that affect the mechanical properties of platesand make orthogonal experiment, eventually come to the better approach technology. Also,the sharping waste blended fiber ratio, matrix of the mass fraction of PP granules, plasticatingtemperature, plasticating time, hot pressure and other technological parameters have aneffecet on the mechanics property, the results show that with1:1waste blended fiber ratio,5min hot pressure time,185℃hot pressur temperature the best shaping condition is50%matrix of the mass fraction of PP granules,190℃plasticating temperature,15MPa hotpressure,5min plasticating time. Under this condition, the mechanics propterties of compouand immingle-hot pressure) by using waste blended fiber [waste polyester/cotton(65/35),cotton/linen (55/45) and polyester fiber], the molding and the parameters, and therelation between their properties.In this paper, blending plastication and immingle-hot pressure are two ways to preparewaste blended fiber composites, for the first time blending plastication mode applied to thewaste plastic blended fiber composite materials, and immingle-hot pressure mode oftechnology of production of composite materials to improve, finally two methods obtained theperformance of compound plates are compared.nd plates are achieved: tensile performance33.91MPa, bend performance48.31MPa, impact performance51.32KJ/m2, and the density offiber compound plates is0.9342g/cm~2.(2)Test and analysis the mechanical properties of compound plates made byimmingle-hot pressure mode, and use Miscellaneous effect analysis the mechanical propertiesof compound plates, and determine the factors that affect the mechanical properties of platesand make orthogonal experiment, eventually come to the better approach technology. Also, the sharping Waste blended fiber ratio, Matrix of the mass fraction of PP fiber, hot pressuretemperature, hot pressure time, hot pressure and other technological parameters have an effecton the mechanics properties, the results show that with5min the best shaping condition is1:1waste blended fiber ratio,60%matrix of the mass fraction of PP fiber,185℃hot pressuretemperature,12MPa hot pressure. Under this condition, the mechanics properties ofcompound plates are achieved: tensile performance45.37MPa, bend performance48.31MPa,impact performance15.32KJ/m2, and the density of fiber compound plates is0.9326g/cm~2.(3)Without adding any additives and compound plate of uniform thickness,50%and60%the mass fraction of PP, using the mode of blending plastication and immingle-hotpressure to make compound plates. The results are immingle-hot pressure plate mechanicalproperties of a good way, but the making process of blending plastication is simple, efficient,and suitable for mass production.
