Tensile Strength of Short Fiber Composite with Epoxy Resin in Bulk Molding Compound
Recent trend of the automobile industry is improving fuel efficiency and decreasing exhaust gas through lightweight parts due to strict environmental regulations.To reduce the weight,development of alternative materials such as aluminum,magnesium and composites have continuously been developed.The automotive seats are the essential parts of safety and convenience for passengers by absorbing shocks and vibrations during driving.Also,the seat is composed of a frame portion to support the load of the passenger and a cushion portion to provide comfort during the ride.Therefore,in order to develop the seat frame as a composite material,sufficient rigidity must be satisfied.In order to reduce the weight of automotive parts,composite materials are widely used,such as the fender,hood,and trunk.The composite materials are composed of reinforcement(fiber)and matrix(resin).The Bulk molding compound(BMC)process is a composite material manufacturing method in which fibers have a short length are mixed with a resin and compression molded.In this study,the composite material specimens were fabricated by BMC method to evaluate the strength of the automotive seat frame using composite material.Composite material specimens were fabricated the epoxy resin(KER828 KUMHO P&B)and three kinds of fibers: E-glass,basalt,and carbon fiber(T-700).And the resin and fiber were in different compression molding with same weight,respectively.Also,to improve the interfacial bonding strength between the epoxy resin and the fiber,the characteristics of the fiber by sizing treatment were confirmed.And the strength of composite specimens made of different length of the fiber as a variable was evaluated.As a result,the mixture conditions for the composite of the automotive seat frame by the BMC method were obtained.
