Knitted Composite Preform Manufacturing
topic
Knitted composite preforms produced by weft and warp knitting of glass, carbon, and basalt fibre yarns provide near-net-shape reinforcement structures for polymer matrix composites that conform to complex tool geometries without the wrinkling that limits woven fabrics in deep-draw moulding, with preform porosity and fibre architecture controlling resin infusion characteristics and mechanical properties of the consolidated composite part.
Role
Enables complex-geometry composite component production by providing drapeable preforms that conform to three-dimensional mould surfaces without cutting and darting woven fabrics, reducing preform assembly labour and improving fibre orientation consistency in complex composite parts for automotive, aerospace, and marine applications where the drapeability advantage of knitted preforms over woven alternatives justifies their selection despite lower directional stiffness.
