摘要： The invention relates to a FRP leaf spring suspension for an automobile including a FRP leaf spring body interposed between a hat-shaped retainer having flanges at its free ends and a U bolt seat having opposed flanges through a rubber pad at its longitudinally central portion. The FRP leaf spring body is fixed through a spring seat to an axle housing by a U bolt passing through mating holes formed in flanges of the retainer and the U bolt seat. A reinforcing fiber impregnated with resin is wound around a central portion of the FRP leaf spring body and is fixed thereto to form unevenness on a surface of the FRP leaf spring body, thereby distributing frictional force between the FRP leaf spring body and the rubber pad uniformly on the frictional contact surface of the FRP leaf spring body, and preventing stress concentration from being generated in the FRP leaf spring body. In another mode, there are formed each unevenness on an upper and a lower surface of the central portion of the FRP leaf spring body, a lower surface of the retainer, and an upper surface of the U bolt seat, thereby preventing stress concentration from being generated in the FRP leaf spring body.

摘要： Apparatus and method for local forced heating of an auto body characterized in that a joint build up with plastic solder on the steel plate of an auto body is placed under a hood which locally covers the joint; then a hot air blast is supplied to the hood. The hot air blast is evenly diffused by means of a stream-rectifying plate installed in the hood, and thus the built up plastic solder can be hardened through local forced heating.

摘要： A fiber reinforced plastics comprises a resin and chopped strands dispersed in the resin, wherein the chopped strands comprise glass fiber chopped strands composed of cut assemblies of glass filaments and high elastic chopped strands composed of cut assemblies of high modulus inorgtanic filaments having higher elastic modulus than the filaments and having 3000 or less number of assembled filaments. By this arrangement, the both chopped strands are closely and uniformly dispersed in the resin and the force interaction between the both chopped stands are enhanced. The resultant plastics has remarkably improved strength and fatigue durability, and higher rigidity than conventional ones.

摘要： The fiberglass reinforced plastics bumper reinforcement fitted with an elastic bumper--which is laterally mounted to the vehicle and which consists, in cross section, of a plurality of rectangular frames stacked in layer--is characterized by forwardly projecting strips formed at the intersections between the front wall of the bumper reinforcement and the top and bottom plates of the reinforcement as well as the horizontally extending webs. These projecting strips on the front wall of the bumper reinforcement alleviate the stress concentrations at these intersections that might be caused when an impact load is applied to the elastic bumper and therefore the bumper reinforcement, thus increasing the fracture strength of the intersections of the bumper reinforcement. The bumper reinforcement is further characterized in that at least one of the top and bottom projecting strips is provided with a protrusion raised upward or downward from the outer surface of the top or bottom plate to further reduce the stress concentration at the intersections.
