JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
JEC Europe 2012 - Curv self-reinforced composite is a new concept in thermoplastic materials that bridges the gap between commodity plastics and traditional fibre-reinforced materials. It is referred to as being “self-reinforced” because it comprises high-performance thermoplastic fibres in a matrix of exactly the same material.
It is 100% polypropylene, but yields stiffness and strength values around 5 times those of regular PP. In addition, Curv has a high strain to failure which in combination with good tensile strength offers tremendously high impact resistance, even at temperatures as low as -189 degrees Celsius. Finally, the material has exceptional abrasion resistance and compressive strength.
Application areas are manifold: suitcases, sports equipment, automotive parts (interior and exterior), anti-ballistic products, etc. This self-reinforced material is also used as a skin material in lightweight sandwich structures, usually in combination with thermoplastic core materials. It can be supplied on rolls or as a sheets in thicknesses from 0.35 to 2.95 mm, a maximum product width of 1360 mm and any length, and can be combined with materials like aluminium, glass, aramid and/or carbon fibres, resulting in a totally new range of thermoplastic composites for a wide range of cost and performance targets.
