Hexcel (Duxford, U.K.) reports that its HexForce NC2 reinforcements have been selected by BMW for the inner structural layer of the carbon fiber roof of its M-series cars. Hexcel’s NC2 patented technology enables carbon fiber multiaxial reinforcements to be produced that are flat, lightweight and provide more uniform coverage than conventional non-crimp fabrics (NCF).

In addition to NC2, Hexcel has been supplying BMW for several years with HexForce PrimeTex 3K spread fabrics for the outer skin of the carbon fiber roof. HexForce PrimeTex fabrics have been processed to provide a very close weave and uniform cosmetic appearance. Hexcel says supplying products tailored to the requirements for the M-series roof was challenging for three main reasons: very specific reinforcement widths are required, with tight thickness tolerances and large volume production.
