SUSPENSION LOWER ARM

PURPOSE:To save the weight of an automobile's arm described at the heading by disposing reinforcing blocks inside a core frame made of woven fabric reinforced plastics and reinforcing the frame with the woven reinforced plastics, thereby showing the I-shaped sectional view at the middle part of the arm. CONSTITUTION:A core frame 14 whose outline substantially runs along the periphery of an arm is molded from glass woven fabric or the like and woven fabric reinforced blocks 15-17 are placed inside the core frame at positions of an arm's base end 10, a stabilizer fitting part 11 and arm's opposite end 12, respectively. A base body 18 is thus prepared. Moreover, the base body is covered with woven fabric 19 over the surface thereof and epoxy resin, unsaturated polyester resin and so on are laminated thereon for reinforcement. The arm is molded in the shape of I in section. The woven fabric 19 is thereby continuously spread in the axial direction from the base end part 10 to the opposite end 12, whereby higher strength and reduced weight may be achieved.
