When the fabric is impregnated with athemoset rein,and rises to the resin and rises to the preset height. There are several measures of lamination such as hand lay-up at room temperature,resin soaking and injection molding,Since both deck layers are interconnected by vertical piles,3D fabric made composites boast excellent mechanical properties and design-verstility against traditional sandwichmaterials.3D fabric now can be widely used in corrosion industry and marine,transport,construction markcts as other areas in the composites industry.
