Automated tape layingATL

A robotic process that lays narrow tows of prepreg or dry fibre onto a tool surface under controlled heat, pressure and tension, steering each tow individually. It enables complex curvature and tailored fibre paths on large structures with high deposition accuracy and low material waste.

Reinforcement fibre pre-impregnated with a controlled quantity of resin, usually a partially cured (B-staged) thermoset, supplied in rolls and stored chilled or frozen until layup. Prepregs give precise fibre and resin content and are the standard material form for high-performance aerospace and motorsport laminates.

The curing of composite laminates in a heated pressure vessel, which applies elevated temperature and gas pressure in addition to vacuum-bag consolidation. The combination suppresses voids and delivers the high, repeatable laminate quality required for primary aerospace structures.
