Heat Resistant Polyimide Film

A high temperature resistant polyimide film and its preparation method. The present invention relates to a polyimide film and its preparation method and solves the problems of honeycomb's and skin panel's core adhesive—polyimide film with insufficient heat resistance, no climbing of bonding core structure and adhesive fillet formation. The high temperature resistant polyimide film is made by polyimide solution, inorganic filler modifier and interface coupling agent by the steps of: under specific temperature and stirring conditions, adding inorganic filler modifier and interface coupling agent to polyimide solution, stirring to obtain the adhesive agent; filtering and degassing the adhesive agent, casting to a stainless steel drum with carrier cloth and release paper to obtain a self-supporting film; then heating and annealing to obtain the final polyimide film. The present invention is applied to high temperature resistant polyimide film and its preparation method.

Method for seaming multi-sectional composite tooling

Method for seaming a multi-sectional composite tooling for use in molding large composite structures. The tooling includes at least two tooling sections that are made from quasi-isotropic sheet molding compound. The two tooling sections are seamed together with a scarf plug at the tooling surface. The scarf plug is composed of specially oriented layers of consolidated quasi-isotropic sheet molding compound. The scarf plug is made from the same type of quasi-isotropic sheet molding compound that is used to make the tooling sections.

Layered tube for improved kink resistance

A catheter shaft is produced by forming a first polymeric layer onto a flexible inner core while maintaining the inner core in a solid state, and solidifying the first polymeric layer, wherein the solidified first polymeric layer fails to bond with the inner core and is slidable thereon upon flexion of the shaft. A second polymeric layer may be formed over the first polymeric layer, and is slidable thereon when the shaft bends.
