VARTM FLOW MODIFICATIONS FOR LOW VISCOSITY RESIN SYSTEMS
摘要:
A vacuum-assisted resin transfer molding (VARTM) method is disclosed, the method comprising: providing a vacuum-assisted resin transfer mold assembly comprising a mold having a first mold surface and a second mold surface arranged to enclose a laminate assembly within a space between the first and second mold surfaces when the laminate assembly is placed on the first mold surface; providing a laminate assembly comprising a laminate pre-form, a peel ply, and a resin distribution media pervious to the flow of a resin, the laminate pre-form having first and second surfaces, the first surface of the pre-form positioned to be in contact with the first mold surface, the peel ply positioned such that the second surface of the laminate pre-form is in contact with the peel ply, and the resin distribution media positioned to be contained within the first and second mold surfaces; positioning at least one resin flow control structure to modify the flow of resin within the resin distribution media; providing at least one inlet and at least one outlet in the laminate assembly such that the resin can be introduced into the assembly through the inlet; arranging and sealing the second mold surface to enclose the laminate assembly within the space between the first and second mold surfaces such that a vacuum can be pulled on the laminate assembly contained within the space between the first and second mold surfaces; applying a vacuum to the mold assembly; allowing the resin to flow into the laminate assembly through the at least one inlet such that the resin
