Abstract
The invention is concerned with an integrated process for the manufacture of polymer and/or composite products, comprising the integration of processing operations to achieve a plurality of material conversion steps, such as impregnation, consolidation and bonding, within one single controlled fabrication cycle. The process includes an in-situ final preparation of at least one composite preform at the location of the moulding operation and an integrated moulding operation comprising a step of providing an additional matrix-functioning material into the mould to at least partially enclose the composite preform, the operation of providing the additional matrix-functioning material providing the pressure for an in-situ final consolidation of the composite product.
