Abstract

The subject matter of the invention is a method for draping on a form, which includes a step of deposition on the form of a first fold support in the form of one or more polymer nonwoven fabrics. The invention further relates to a thermoplastic nonwoven material manufactured with a nonwoven fabric of polymer fibers.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A thermoplastic nonwoven material, comprising a nonwoven fabric of polymer fibers. 
     
     
         2 . A material for producing a first ply for drape forming on a former, consisting of a nonwoven fabric of polymer fibers. 
     
     
         3 . The material as claimed in  claim 2 , wherein the polymer fibers comprise PEEK. 
     
     
         4 . The material as claimed in  claim 2 , wherein the polymer fibers comprise PEI. 
     
     
         5 . The material as claimed in  claim 3 , wherein the polymer fibers consist of 100% PEEK fibers. 
     
     
         6 . The material as claimed in  claim 3 , wherein it comprises from 60% to 70% of PEEK fibers. 
     
     
         7 . The material as claimed in  claim 2 , wherein the polymer fibers comprise polyamide. 
     
     
         8 . The material as claimed in  claim 2 , wherein it consists of a needle punched nonwoven. 
     
     
         9 . The material as claimed  claim 2 , wherein it consists of a hydroentangled nonwoven. 
     
     
         10 . The material as claimed in  claim 2 , wherein it consists of a calendered nonwoven.
