| description | The invention relates to a preparation method for a glass fibre reinforced resin composite plate spring. The method comprises the following steps of: respectively soaking a glass fibre cloth and a glass fibre filament in epoxy resin, laying a layer on the upper and lower surfaces of a core model by using the glass fibre cloth; in the case of existing a preset value of the appropriate tensile force, winding the glass fibre filament on the core module, wherein the applied tensile force to the glass fibre filament gradually decreases along with the number of winding layers in the winding process; laying a layer of glass fibre cloth after the completion of winding; performing die assembly by the conventional manner to obtain an incompleted plate spring in embryo, and solidifying to obtain the glass fibre reinforced resin composite plate spring. The plate spring product prepared by the method provided by the invention has more excellent strength, is stronger in fatigue resistance than steel materials and is above |
