Guide network is applied to the composite vacuum assisted molding process of the high permeability of guide medium, the extrusion of five line of three-dimensional network structure, is advantageous to the resin flow and infiltration. The user can according to the required flow rate of the molding products, choose different square gram of diversion of cloth, can also according to the structure of the molding products, designing multilayer diversion cascade laying structure, realize the effective control of the resin flow state, so as to improve the reliability of complex products molding process and the quality of the product. This product can be arbitrary clipping, suitable for different shapes of products, consumption, low efficiency, which greatly reduces the cost of composite.
