Abstract
A novel preform screen for use in producing preforms for structural liquid composite molding is described. The screen has a raised edge provided around the screen to catch fibers as they are directed toward the screen surface during production of a preform. The preforms produced have a perimeter which is composed of chopped rovings oriented parallel to the edges of the preform.
