Abstract
Official abstract text for this publication.
A method of forming a closed cell thermoplastic foam duct and a method of forming a duct and attaching it to an aircraft environmental control system. The environmental control system includes a duct made of closed cell thermoplastic foam, such as polyvinylidene fluoride foam.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of forming a duct, the method comprising the steps of: skiving a thermoplastic bun having a closed cell structure to form a sheet, the bun comprising an expanded foam polyvinylidene fluoride (PVDF) material; cutting the sheet to create a first edge and a second edge of the sheet; forming a crenulation pattern in the first edge of the sheet so as to form a first crenulated edge; forming a crenulation pattern in the second edge of the sheet so a…
