Filler, filler construction process and filler curing structure

Abstract

The invention provides a filler for repairing a notch of a glass fiber reinforced composite sheet, a filler construction process and a filler curing structure. According to the filler construction method, a notch of a member to be decorated is processed to have a shape of a dovetail groove with a large internal opening and a small external opening, and the shape of the dovetail groove facilitatesthe adhesion of the filler; the filler is added twice to form an inner reinforcement layer and an outer reinforcement layer, and the reinforcement layers are supplemented with a middle fiber griddingcloth layer, so that the inner reinforcement layer and the outer reinforcement layer are more closely combined; the fiber gridding cloth layer can be used as joint ribs, so that the filler forms a whole with the composite sheet, and the adhesion of the filler to the surface of the notch is further improved; the inner reinforcement layer is of a convex headless cone structure, the fiber gridding cloth layer covers the cone structure, the cone structure can be held after the filler is cured, and the adhesion of the filler to the surface of a fixing bolt is improved.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and in particular relates to a filler for gap repair of glass fiber reinforced composite boards, a construction process of the filler, and a solidified structure of the filler. Background technique [0002] Glass fiber reinforced composite material not only has a small shrinkage rate after molding, but also has strong corrosion resistance. And it has the characteristics of strong toughness, environmental protection, no radiation, and strong plasticity. This kind of material can easily realize various artistic styles, with random shape and rich texture, so it is deeply loved by designers. Building exterior decoration surfaces, handicrafts, architectural sketches, and sales cars are all made of this kind of material. It is widely used in various engineering projects. [0003] Common glass fiber reinforced composite materials include GRP (glass fiber reinforced thermosetting plast...

AI Technical Summary

Problems solved by technology

[0004] However, after a long period of exposure to the wind and the sun, there will be a phenomenon that the drilling position will be repaired and peeled off in the later stage. Figure 10 shown

The main reason for this problem is that the adhesion between the filler and the surface of the fixing bolt and the inner surface of the gap is not enough, and at the same time, it falls off due to external temperature changes, internal stress concentration release, etc.
