Embodiment Construction

[0013] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, a new type of vacuum introduction method for preparing ultra-thick composite sheet devices includes a mold 12, and the surface of the mold 12 is sequentially covered with a lower flow guide medium 11, a lower release cloth 10, a preform 7, and an upper release cloth. 9. On the guide medium 8 and the vacuum bag 6, a sealing tape 5 is arranged around the mold 12, and the sealing tape 5 seals the vacuum bag 6. The vacuum bag 6 is provided with a resin pipeline 13 and an air extraction pipeline 14, and the resin pipeline 13 Connect the injection pipe 4, the injection pipe 4 is connected to the resin barrel 3, the air extraction line 14 is connected to the air extraction pipe 2, and the air extraction pipe 2 is connected to the vacuum system 1.

[0015] Clean the surface of the mold 12, paste the sealing tape 5 around the mol...

Abstract

The invention provides a novel device and technology for manufacturing an ultra-thick composite plate by means of vacuum infusion, and aims at solving the problem that the ultra-thick composite plate is hard to manufacture by means of vacuum infusion. The thickness of the composite plate is larger than 8 mm. According to the scheme, a layer of flow guide medium is laid on the upper surface of a pre-forming body, and a layer of flow guide medium is laid on the lower surface of the pre-forming body; after resin is poured, the resin on the upper surface of the pre-forming body downwards permeates into fibers through gravity and surface acting force, and the resin on the lower surface of the pre-forming body upwards permeates into the fibers through surface acting force; and the distance of a resin infiltration reinforcement body is shortened, the resin pouring time is shortened, the defects of the composite plate are reduced, and the success rate of the composite plate is increased. The technical problem that the ultra-thick composite plate or product is hard to manufacture by means of a vacuum infusion method is solved, the application range of the vacuum infusion method is widened, and meanwhile a thought is provided for low-cost manufacturing of the ultra-thick composite plate or product.

Description

technical field [0001] The invention relates to a device and a process for preparing ultra-thick composite material plates by a vacuum introduction method. Background technique [0002] Fiber-reinforced composite material is a new type of high-performance material, which has many excellent characteristics such as high specific strength, large specific modulus, corrosion resistance, etc., and is used in many fields such as aerospace, rail transit, automobile, sports and leisure. At present, the forming process of composite materials mainly includes autoclave forming process, pultrusion forming process, winding forming process, resin transfer molding, vacuum introduction and many other forming processes, among which the vacuum introduction forming process is a low-cost and easy-to-operate process. The liquid forming process has great advantages in the manufacture of composite products. However, due to the limitations of its process characteristics, it is difficult to realize ...
