HALF-FINISHED PRODUCT OF A BUMPER, AND PROCESS FOR PRODUCING THEREOF |
摘要 |
<p>A process for producing a reinforced plastic motor vehicle bumper includes the steps of placing a woven roving (17) on a center section of a preform screen (10) that is retained by a vacuum draw from a suction fan (16). Chopped glass fibers (20) and a curable binder are sprayed onto the preform screen and woven roving. A second layer (22) of woven roving is placed onto the center section of chopped glass and first layer (17) of woven roving. Either the excess trim (39) is trimmed by a cutting die (50) before the preform is cured or the die is first cured and then the excess trim is trimmed by a cutter using a plastic base (35) in the screen that circumscribes the contoured section of the preform screen.</p> |
