Abstract
A system is reported which automates the methodology needed to design complex 3D woven composite reinforcements. The system generates the design code enabling automatic preform manufacture on a conventional loom and provides specific data for composite modelling and analysis. This is a fundamental design tool and facility that amalgamates the collective interests of a multi-disciplinary group researching the many facets of textile composites. The cross-sectional program (XS program) has to facilitate the design rationale and methodology necessary for the production of a diverse range of flat and complex shaped reinforcements in a variety of weave architectures. Program outputs, for use within the textile modelling and analysis software and for fabric analysis data ofthe different architectures, are provided in a compatible format. The program and data generated has evolved into the foundation for a knowledge based system for fibre reinforced composites. This paper outlines the specification and attributes of the program, verifying its capabilities by designing and manufacturing complex fabric architectures in the form of a lower limb prosthesis and T-section reinforcement. The paper also indicates some other areas of on-going research to provide basic information for the program database.
