ABSTRACT

A filament winding process of commingled yarn is investigated. This study aims to verify the feasibility of the proposed winding process experimentally. A laboratory scale winding system is built which can perform in situ consolidation using a hot nitrogen gas torch. The degree of impregnation is evaluated for different process parameters including the hot nitrogen gas temperature, the process speed and the compaction force to provide a process window.

 

Keywords : commingled yarn, filament winding process, degree of impregnation, in situ consolidation
