Abstract

The invention discloses a fiberglass product trepanning reinforcement device and method in the technical field of fiberglass and aims at solving the technical problem that in the prior art, cracking is likely to happen when the trepanning position of a fiberglass product is fastened. The fiberglass product trepanning reinforcement device comprises a cushion plate, a through hole is formed in the cushion plate, a throat pipe is arranged at the position of the through hole, and multiple notches are formed in the tail end of the throat pipe. By means of the fiberglass product trepanning reinforcement device, the overall quality of fiberglass can be ensured, the stress condition at the trepanning position of the fiberglass is improved, the strength at the trepanning position of the fiberglassis improved, and the risk of cracking at the trepanning position of the fiberglass is lowered. By means of the fiberglass product trepanning reinforcement method, operation is simple, installation isconvenient, specifications are diversified, selection is convenient, and maintainability is good.

Description

technical field

[0001] The invention belongs to the technical field of glass fiber reinforced plastics, and in particular relates to a device and method for opening and reinforcing glass fiber reinforced plastic products. Background technique

[0002] In industrial production, FRP parts without embedded parts are often installed. If holes are directly opened on FRP and fastened with fasteners, the surface strength of FRP will be reduced due to the low elastic modulus and low interlayer shear strength of FRP. Risk of cracking at openings in large FRP surfaces. At present, there is no way to increase the strength of FRP openings by adding reinforcement plates. The commonly used method is to embed reinforcement plates inside FRP, but it will increase the thickness of FRP, and after FRP is connected with other materials, it may still cause holes on the surface of FRP. If there is a crack, the opening position will also be limited by the position of the reinforcing plate. The i...
