Abstract

There is a global renewal of interest in manufacturing technology for lightweight materials, with a major focus on automotive composites. This is evident in the national initiatives embarked in recent years, notably the Institute for Advanced Composites Manufacturing Innovation (IACMI) led by the University of Tennessee in the USA; the Institute for Carbon Composites in Germany (LCC); and the National Composite Center led by Nagoya University in Japan. It is of interest to note that carbon fibres and textile structural composites (TSC) are the key focuses in these manufacturing initiatives. This presentation explains why and offers suggestions on future directions for TSC.

TSCs are composite materials reinforced by textile structures for primary structural applications. Although textile structures have long been used for composite reinforcement, serious use of textiles for structural composites did not occur until the entering of the space age with the development of carbon fibres and multiaxial 3D textile preforms. The need for affordable composites that have significantly improved through-the-thickness strength and damage tolerance intensified the development of a wide variety of textile preforms, which established the foundation for the use of textile composites for aircraft primary structures. Future growth and widespread usage of carbon fiber in automobiles depends on the availability of low cost carbon fibers and affordable composite manufacturing processes.

In this presentation, after a review of the unique characteristics of TSCs and their advanced applications, we will discuss the lessons learned in the development of TSCs. This will be followed by an introduction to the current approaches to reduce the cost of carbon fiber cost through the development of low cost renewable carbon fiber precursors. We will conclude by examination of future opportunities of smart TSC for vehicle and human health monitoring using multifunctional composite nanofibres.
