Vectorply Corporation has introduced a new fabric in its VectorUltra line of composite reinforcements.

The 94 oz/yd² carbon quadraxial fabric, entitled C-4QX 9400, is an all-standard modulus carbon fiber quasi-isotropic reinforcement fabric that is suitable for tooling, panel, and thick section advanced composite applications.

C-4QX 9400 is made using a balanced and symmetric stacking sequence of approximately 400 gsm carbon plies. The architecture of the fabric provides a very low and consistent coefficient of thermal expansion (CTE) and an un-coupled (non-potato-chipping) laminate, an suitable combination for high-performance composite tooling, which experience large temperature changes, the company says.

The symmetric construction makes it possible for panel manufacturers to make ultra-flat panels, and the 3200 gsm areal weight allows for minimal labor requirements for building thick cross sections.  In addition, the quasi-isotropic nature also provides high bearing strength, which combined with its high areal weight, is a perfect material for inserts and hard points requiring mechanical fasteners.

The C-4QX 9400 fabric can be used in both prepreg and resin infusion applications. It is also available in a ‘tapered’ option along the fabric width, allowing for scarf joining and consistent thickness across joints.
