The invention discloses a vacuum
infusion method and a product thereof. The process comprises the following steps: treating a die, spraying a gel coat, laying a surface felt, laying multilayer reinforcing materials, laying a flow guide screen, laying a layer of multi-axial cloth, laying a flow
guide tube, laying vacuum film bags, vacuumizing, injecting materials, curing, removing the flow
guide tube and the vacuum bag film, and releasing the film, wherein laying
layers of the multilayer reinforcing materials are as follows: two
layers of multi-axial cloth, a sandwich felt, two
layers of multi-axial cloth, a sandwich felt, fixed PVC reinforcing ribs, at least two layers of multi-axial cloth and a composite felt. An isolation film layer is reduced, and the remainder amount of resin on the laying layers is obviously reduced in the vacuum infusion process disclosed by the invention, thus the
utilization rate of the resin is greatly increased, and the resin of the resin on the surface of the obtained product is increased, and the strength of the product is obviously increased; and the generation amount of garbage such as an isolation film is reduced, the production cost is reduced, and good social and
economic benefits are achieved.
