“…The 3D weaving process utilised within the University of Ulster's Engineering Composites Research Centre (ECRE) has been in use for over 10 years and is a robust process based on minimal modifi cation to existing Jacquard based weaving technology. Preforms with reinforcement in the three principal directions can be woven, in addition to net shaped preforms such as "T" pieces, "I" beams, wing stiffeners, trim tab aerofoil sections and leg prostheses 6,7 . The integration of the binder yarn during the preform weaving process in the third dimension has the potential to suppress failure through delamination by essentially holding the layers together.…”

This paper describes a feasibility study to assess the viability and potential benefit of 3D woven textile reinforcements with metallic yarns integrated into the structure. It reports the results from a study of the manufacture and mechanical testing of hybrid 3D woven composite materials. The hybrid structures were manufactured using carbon fibre and aluminium wire, and subsequently impregnated with a two-part aerospace resin system. Details are given concerning the manufacturing issues with hybrid materials, and the results from mechanical testing of the first of these novel hybrid structures are examined. In addition there is a discussion of possible future developments in this area. Some preliminary data within this paper was used in a presentation at TexComp-8 Nottingham, October 2006.

Interest in 3D woven carbon fibre composites has increased within industries such as aerospace, automotive and marine, due to their high strength to weight ratio, their increased tailorability and their capacity to be manufactured into near net shape preforms, thereby reducing parts count, assembly time, labour intensity and costs. It is vital that critical areas of concern such as damage (and in particular damage initiation and development) are studied and understood, thereby reducing the limiting factors to their acceptance. The damage initiation and subsequent intervals of development for ILSS (Interlaminar Shear Strength) were determined experimentally. Particular focus is paid to the significance of binder edge and binder middle testing and the influence of through-the-thickness (T-T-T) reinforcement in relation to damage types and development. Control samples for binder edge and binder middle loading locations were tested to failure as a means of determining an average point of failure, allowing the generation of testing intervals. The performance and architecture of samples from each incremental interval were characterised using a combination of graphical analysis and optical microscopy with the aid of dye-penetrant to highlight fibre damage and matrix cracking. Samples displayed specific damage initiation points, thus allowing the generation of a damage guide relating to applied force. In addition, the results imply that a relationship exists between the location of applied load and subsequent damage, thus showing the significant influence played by the T-T-T binder loading location on damage development within 3D woven carbon fibre composites. Some of the preliminary data shown in this paper was presented at IMC23 at the University of Ulster, UK in August 2006 and at Texcomp 8 in Nottingham, UK October 2006.

“…Currently, the only reported application of three-dimensional woven composites in the building industry is for composite I-beams used in a ski chair-lift build in Germany [20]. While still at a demonstration stage, biomedical devices using three-dimensional woven composites, such as a leg prosthesis, are also being evaluated [21].…”

Three-dimensional fibre-reinforced polymer composites made by the textile processes of weaving, braiding, stitching and knitting have tremendous potential for improving the performance of composite structures and reducing their cost of manufacture. Current applications of three-dimensional composites are described, including examples in the aerospace, maritime, automotive, civil infrastructure and biomedical fields. However, to date the use of three-dimensional textile composites has not been exploited for many potential applications, and some of the issues impeding the widespread use of three-dimensional textile composites are identified.
