HiMax™ Multiaxial reinforcements, also known as non-crimp fabrics (NCF), are multiple layers of unidirectional fibers, with each ply placed in a different orientation or axis. These layers are then typically stitchbonded to form a fabric. The range includes fabrics manufactured by Hexcel in Leicester, UK at the site that was formerly Formax and was acquired by Hexcel in 2016. Multiaxial reinforcements provide strength and stiffness in multiple directions depending on the controlled orientation of the fibers. The weight distribution in the fabric is optimized and it is possible to mix fiber types.
HiMax™ reinforcements offer several advantages over traditional fabric forms:
The non-crimp concept allows in-plane mechanical properties to be enhanced, such as tension and flexion. In a complex lay-up there is less material waste and the lay-up time is reduced by using thicker materials. High tow count fibers can be used.
