Abstract

The invention discloses a diversion net for vacuum perfusion and a preparation method and application thereof. The diversion net comprises a net body. The net body is of a rhombus structure. Multipledense grids are arranged on the net body. The grids are of rhombus structures. The grids are 2*2 mm. The thickness of the net body ranges from 0.8 mm to 1.1 mm. The adjacent angles of the grids of therhombus structures are 70 degrees and 110 degrees correspondingly. The net body is made from polypropylene resin and polyethylene resin materials and prepared through an extruder and a dragger, the method is simple and efficient, and high-speed diversion is achieved.

Description

technical field [0001] The invention relates to a diversion net, in particular to a diversion net for vacuum perfusion, a preparation method and application thereof. Background technique [0002] Among the current materials, composite materials are widely used because of their light weight and high strength. The manufacturing process for composite materials is also constantly improving and innovating. From the initial hand lay-up, to mechanized spraying, pultrusion, molding and other processes, to the emerging vacuum infusion process. [0003] Vacuum infusion process refers to laying reinforcing materials (glass fiber, carbon fiber, sandwich material, etc., different from vacuum bag process) on the mold first, then laying vacuum bags, and extracting the air in the system to form a negative pressure in the mold cavity , use the pressure generated by the vacuum to press the unsaturated resin into the fiber layer through the pre-laid pipeline, let the resin infiltrate the rei...
