Method and apparatus for the contact application of yarns of pre-impregnated fibres in particular for making complex structures of composite material polymerised by ionisation

摘要

An impregnated fibre supplied from a spool, etc. and deposited onto a surface using only a supply roller, etc. pressed against the surface. When a desired length has been deposited the fibre is cut a point between the surface and the roller. An Independent claim is also included for a device for performing as above which includes a numerically controlled machine head moving over the surface and including devices for braking and cutting the fibres. Preferred Features: The fibre is impregnated by a resin polymerized by ionizing radiation. Hot or cold air is directed from the head onto the surface.
