Publication number: 20190248063Abstract: An article useful as a forming and cutting tool for molding composite material and cutting non-planar edges of molded composite material. The article includes an upper and lower die. The upper die includes an upper pressure pad with an upper shearing edge and an upper mold with a cavity. The lower die includes a lower pressure pad and a lower mold with a core and a lower shearing edge. The upper die is adapted to come into contact with the lower die so that the upper pressure pad and upper mold apply pressure to the lower pressure pad and lower mold to form a composite material blank into a formed composite structure. The upper die is adapted to contact the lower die so that the upper shearing edge bypasses the lower shearing edge to form a non-planar cut in at least a portion of a formed composite.Type: ApplicationFiled: October 20, 2017Publication date: August 15, 2019Inventors: Jay M. Tudor, Jeffrey D. Wenzel, Scott R. Kaleyta

Publication number: 20180043584Abstract: The present invention relates to a process to reduce internal stresses in insulation molded onto complex pipes, preferably complex subsea pipe, to reduce cracking in the molded insulation. Insulation materials applies to complex pipes comprising branches, i.e., valves, and the like, may be susceptible to cracking at, or near where the branch connects to the pipe as the coating of insulation material cures or hardens. The process of the present invention aims to reduce post molded cracking by reducing molded in stress at the branch/pipe junction. This is accomplished by providing a preform at or near a branch/pipe junction prior to applying the coating of insulation material.Type: ApplicationFiled: March 18, 2016Publication date: February 15, 2018Inventors: Jie Feng, Mark W.

Patent number: 6926856Abstract: The present invention thus provides a fabric-laminated plastic part and a novel process where the fabric edges are covered with a second plastic component that adheres both to the fabric and to the first plastic material. A first plastic substrate component is prepared with an adhered fabric surface area and then the edges of the fabric are overlapped by a second molded-on, plastic edge-covering component. The second material covers the fabric edge to provide an aesthetically pleasing surface. This construction produces a more durable fabric edge covering and eliminates the tendency of the fabric to peel off the molded part during use.Type: GrantFiled: July 29, 2002Date of Patent: August 9, 2005Inventors: Michael E. Hus, Joseph A. Langmaid, Curt E. Peterson, Jeffrey D. Wenzel

Patent number: 6719381Abstract: A protective enclosure is disclosed that provides protection and energy management for a sensitive or fragile part or device that can be enclosed. The enclosure comprises one or more rigid structural components and one or more soft touch surface components from which one or more ribs originate and pass through the rigid structural component(s) to provide the energy management for the part or device when it is enclosed. The soft touch surface and rib material can be a low modulus, plastic material such as a thermoplastic elastomer and can optionally be foamed to provide further softness for the soft touch surface effect and/or for the energy management needs in the pass through ribs. Thermoplastic polyurethane (TPU) is a particularly suitable thermoplastic. It has also been found that the protective enclosure can be designed to utilize the soft touch component to provide a substantially continuous liquid and dust resistant seal for any moveable or removable structural components.Type: GrantFiled: June 4, 2002Date of Patent: April 13, 2004Assignee: Dow Global Technologies Inc.Inventors: Robert J.
