Latest Patents

One of her latest patents is for anisotropic continuous strand mats. This innovation involves a new pattern for continuous strand fiberglass mat that enhances the torsional rigidity of molded structures. The design features an elongated elliptical loop where the strands are laid on the conveyor, resembling lazy whirl formations or concentric circles. The diameters of these patterns are dependent on properties such as bending rigidity and torsional rigidity, and the lay-down pattern exhibits a cycloidal nature. Another significant patent is for shaping means for the production of fiber-reinforced preform articles. This shaping apparatus includes a first screen that defines the contoured shape of the article and a second screen with a complementary surface. It also features at least one resilient presser rod that engages the fiber matting, pressing it into the screens as they close together. This apparatus is particularly suitable for manufacturing glass fiber-reinforced automobile bumpers.
