Abstract

A tubular fibrous architecture is disclosed. According to one aspect, the tubular fibrous architecture includes a closed tubular part in at least one of its ends or bottom. The closed tubular part includes an architecture in which a textile material, such as a thread, roving, ribbon or bundle of threads, is continuously output from the bottom. Each textile material that is output from the bottom is continuously wound about the tubular part. All of the textile materials at the junction between the bottom and the remainder of the tubular part are continuous and there is a continuous geometric transition between the bottom architecture and the architecture of the remainder of the tubular part such that the textile materials in the tubular part cross over. A method of making such a tubular fibrous architecture is also disclosed.
