TenCate Advanced Armour will be introducing a method of 3D moulding for their TenCate Liba armour system at DSEi.
According to TenCate, the 3D moulding method will allow for the replacement of existing key components of armoured vehicles – such as hatches, doors and bonnets, all traditionally made from steel – with all-composite solutions.
TenCate explain that their engineers have recently completed the design and testing phases of the project and a completed solution is now being field tested.
The head of Research and Development, Dr. Paul Bourke, emphasises the thorough and continuous testing and research, as well as the close cooperation with the vehicle manufacturer as important for the success of the project, “The challenges of the 3D moulding project have been many, the most significant being to provide the rigidity of the steel by placing the fibres accurately, and securing that there are no ballistic weak points in the design by constantly seeking to achieve the correct weave architecture and to avoid cuts”.
TenCate say the key technologies in the solution are 3D TenCate Liba ceramics and a no-cut aramid backing. A lot of mechanical design considerations had to be made, e.g. structural analysis, insert design, shaping, integration, testing and environmental properties. They say this technology allows vehicle manufacturers to reduce the overall weight of the vehicle significantly, while actually improving the level of protection. The reduced weight and increase in protection are important steps to reduce life cycle costs and improve the survivability of the vehicle and its passengers.
Traditionally, composite armour solutions have been add-on armour panels and spall liners. Those work with the existing steel or aluminium armour of the vehicle. Dr. Bourke says “The long-term perspectives for this new 3D moulding technique is that we will be able to replace several heavy steel components from vehicles with lighter and stronger all-composite solutions – thus getting both lighter and better protected vehicles”.
