Woven construction of high performance fibres plays important roles in ballistic protection. This paper reports on the recent research on the engineering design and evaluation of 2D and 3D fabrics emphasising on the influence of construction of ballistic fabrics on ballistic performance. Based on preliminary research, a new concept of fabrics with material continuity and enhanced yarn gripping was put forward. Accordingly, fabrics with enhanced yarn gripping were engineered, manufactured, and evaluated, and results showed improved ballistic performance in terms of both projectile penetration and trauma impact. Based on the new concept, 2D and 3D fabric constructions were discussed for ballistic protection. Formation of 3D panels was investigated and it was found that angle-layering for creating panesl improves the isotropy and hence better impact performance. Hybrid design of ballistic panels from the commonly used woven and UD fabrics indicated that it is possible to improve the ballistic performance by using layer materials according to the impact mechanism. FE simulation was also carried out for the investigation of strain distribution in the ballistic fabrics and panels, which provides information for optimisation of fabric construction.
