Embodiment 1
[0029] Embodiment 1: A repairing process of FRP carriage composite board, which is used to repair the area 2 to be repaired on the FRP carriage composite board 1 due to debonding or hollowing of the core material and the panel.
[0030] The repairing process of the FRP carriage composite board includes the following steps:
[0031] (1) Apply an easy-to-remove anti-adhesive layer on the panel in the area to be repaired 2. The anti-adhesive layer is formed by release wax or release agent.
[0032] (2) At the upper end of the area 2 to be repaired, open a microhole that penetrates the panel and reaches between the panel and the core material. The diameter of the pores is relatively small, for example 4mm.
[0033] (3) Use a syringe to inhale the prepared glue (refer to the technical parameters of the glue), and discharge the air in the syringe to avoid a large amount of air in the newly injected glue, resulting in a new hollow, and then use the needle The barrel injector injec...

Abstract
The invention relates to a glass fiber reinforced plastic carriage composite board repair process. The repair process comprises the following steps: (1) coating the panel of a to-be-repaired area with an easily-removed anti-glue layer; (2) arranging, at the upper end portion of the to-be-repaired area, a micopore that penetrates the panel and reaches between the panel and a core material; (3) injecting glue between the panel and the core material through the micopore by using a syringe injector; (4) standing until the glue flows to the lower end portion of the to-be-repaired area, and extruding the panel so that the to-be-repaired area is coated in place by the glue and the air between the panel and the core material is exhausted; (5) compacting the panel and the core material until the glue is completely solidified; (6) removing the anti-glue layer so that the glue flowed out of the micropore is removed; and (7) filling the micopore with gel coats, and completing the repair when the gel coats are solidified. In the repair process provided by the invention, a minimally invasive construction method is adopted so that the original surface of a carriage board is protected to the maximum, the surface of the repaired carriage board is smooth and beautiful, and the repair efficiency is quite high.
Description
technical field [0001] The invention relates to a process for repairing the area where degumming or hollowing occurs on a composite plate of a fiberglass steel car box. Background technique [0002] Due to its high strength and light weight, FRP carriage composite panels are now widely used in the field of transportation. Due to the development of FRP car composite panels in the direction of large areas, problems such as debonding of core materials and panels will occur during production and long-term use. According to the statistics of the logistics company, 30% of the vehicles need to repair the box plate every year. Because the carriage is already installed and in use, it is not easy to restore. The usual method is to cut off the FRP panel, re-lay the fiber, apply the gel coat, and polish it with water. There are many processes in such a treatment method, and the construction time is as long as one day; and the appearance of the repaired box board is often uneven and h...
