Abstract
Official abstract text for this publication.
Uses of low molecular mass, non-evolutive polyamide resins for making composite articles are described. Articles obtained from such resins having good mechanical properties, such as rigidity, breaking load, impact resistance, and fatigue behavior in particular, even when the articles are manufactured according to cycles shorter than those usually used, and without any processing before or after the manufacture of the composite articles, are also described.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for the manufacture of a composite article by molding, the process comprising at least the following steps: a) obtaining a composition comprising a non-evolutive polyamide resin having a weight-average molecular weight Mw of between 5000 g/mol and 25000 g/mol and a concentration of amine terminal groups (ATG) of less than or equal to 5 meq/kg and a concentration of carboxylic terminal groups (CTG) of between 100 and 1000 meq/kg, or a concentr…
