Carbon Fibre and Technical Yarn Knitting Machines
topic
Technical yarn knitting machines modified for carbon fibre, glass fibre, and aramid processing use enlarged needle hooks, reduced gauge from 3.5 to 7 needles per inch, slow machine speeds of 5 to 20 rpm, and yarn guide modifications that minimise fibre bending radius to prevent brittle technical fibre breakage during loop formation, producing knitted performs for composite reinforcement with defined fibre architecture and porosity.
Role
Produces knitted carbon fibre and technical yarn preforms for composite reinforcement applications where the knitted loop structure provides superior drapeability and conformability over woven fabrics for complex three-dimensional composite shapes, enabling composite component production with fewer fabric layers and reduced waste compared to cutting woven fabrics to shape for non-flat composite geometries.
