Publication number: 20100285297Abstract: A method of manufacturing a fiber-reinforced article. The method includes the steps of providing a mat fiber stricture defining voids therein. A membrane structure is applied over at least a portion of the fiber structure. The membrane structure includes a microporous membrane. At least the microporous membrane of the membrane structure has an oil resistance rating of at least a number 8 determined by AATCC 118 testing. A resin and hardener mix is provided. The resin is infused into voids of the fiber structure by applying a vacuum to the fiber structure and the membrane structure wherein the membrane structure inhibits the flow of resin therethrough.Type: ApplicationFiled: November 18, 2008Publication date: November 11, 2010Inventors: Vishal Bansal, Nusrat Farzana

Patent number: 7794827Abstract: A self-supporting energy absorbing composite includes: i) a solid foamed synthetic polymer matrix; ii) a polymer-based dilatant, different from i) distributed through the matrix and incorporated therein during manufacture of i); and iii) a fluid distributed through the matrix. In another embodiment, a self-supporting energy absorbing composite includes: iv) a solid, closed cell foam matrix; v) a polymer-based dilatant, different from i), distributed through the matrix; and vi) a fluid distributed through the matrix. In both embodiments, the combination of matrix, dilatant and fluid is such that the composite is resiliently compressible.Type: GrantFiled: May 9, 2008Date of Patent: September 14, 2010Assignee: Design Blue Ltd.Inventors: Richard Martin Palmer, Philip Charles Green
