Title: Innovations of Eugene J Grandlic
Introduction
Eugene J Grandlic is a notable inventor based in Sheboygan, WI (US). He has made significant contributions to the field of materials science, particularly in the development of advanced composite materials. With a total of 2 patents, his work focuses on enhancing the properties and applications of fiber-reinforced plastics.
Latest Patents
One of his latest patents is titled "Matched die molding of fiber reinforced plastic articles." This innovation involves producing lightweight glass fiber reinforced plastic articles using matched dies. The process combines fibrous reinforcing materials, such as glass fibers, with a foamable unsaturated polyester resin composition. The matched dies are closed and compressed, allowing the resin composition to fill the mold cavity and wet the fibrous reinforcing material. Afterward, the matched dies are separated to increase the volume of the mold cavity by at least 50 percent greater than the closed volume. This method results in products with a density less than 67 percent of corresponding reinforced plastic articles that are not foamed. The unsaturated polyester resin composition includes an azo blowing agent to facilitate resin cure and foaming, leading to products that exhibit superior energy absorption characteristics compared to other fiber-reinforced plastic products.
Another significant patent is for a "Clay tile pipe joint seal containing foamed unsaturated polyester resin." This invention provides an improved joint seal for clay tile pipes with bell and spigot configurations. The joint seal utilizes unsaturated polyester resin in a foamed, low-density state, preferably below about 50 pounds per cubic foot, enhancing the performance and durability of the pipe joints.
