Publication number: 20130192384Abstract: The invention pertains to a method and apparatus for testing the tensile strength of a material, particularly an electrically nonconductive material, at a temperature above ambient temperature. The test method is useful for determining the potential suitability of a material for use as a development medium in a thermal development process for preparing relief printing forms. One embodiment of the method includes mounting the strip between upper and lower chucks of a tensile test machine; positioning a means for generating a hot air stream adjacent the strip so that the stream does not impinge the strip; heating the hot air stream to a predetermined temperature above ambient temperature; repositioning the hot air stream so that the stream impinges the strip; and starting the tensile testing when the hot air stream at the predetermined temperature begins heating the strip.Type: ApplicationFiled: July 27, 2012Publication date: August 1, 2013Applicant: E I DU PONT DE NEMOURS AND COMPANYInventors: HAO CHANG, George J. Broda, III, Clifford K. Deakyne, Stacy M. Hamlet

Publication number: 20110209811Abstract: Perfluoropolymer parts containing (reinforcing) fibers oriented parallel to the surface of the parts may be joined by frictional welding processes such as vibration welding and ultrasonic welding without disturbing the orientation of the fibers. The parts may be used directly or cut into other shapes. Such parts are useful where high temperature resistance and/or chemical resistance is desired along with good physical properties such as strength and/or toughness. These types of parts include gaskets and seal rings.Type: ApplicationFiled: May 9, 2011Publication date: September 1, 2011Applicant: E. I. DU PONT DE NEMOURS AND COMPANYInventors: J.

Patent number: 5506052Abstract: A process for the production of structural and semi-structural composites formed by compressing planar layers of nonwoven preform materials formed from aqueous blends of reinforcing fibers and thin thermoplastic fluoropolymer flake. The flakes have an irregular periphery with microfibrils extending therefrom, having a Canadian Standard Freeness greater than 800. The planar layers which are unconstrained in the in-plane direction are preconsolidated by heating the layer to above the melting point of the fluoropolymer, the applying pressure normal to the plane of the layer causing the fluoropolymer to flow thus orienting the fibers in the plane of the layer. The composites are useful in applications which require higher strength and/or modulus, and where chemical and/or heat resistance is needed, as in chemical processing.Type: GrantFiled: November 4, 1994Date of Patent: April 9, 1996Assignee: E. I. Du Pont de Nemours and CompanyInventors: Clifford K. Deakyne, Gregory P. Weeks
