ABSTRACT:
A process for producing a motor vehicle bumper includes the steps of depositing chopped glass fibers (19) and a curable binder (24) to a center section (38) of a preform (11) that is retained on a preform screen (14) by a vacuum draw from a suction fan (15). A ratio of shredded structural reinforced injected molded plastic (23) and glass fiber (19) is sprayed to form end sections (41) and flanges (39) of the preform (11) along with binder (24). The preform (11) is then cured on the screen (14).
