Obtaining preforms by additive fused deposition modelling (FDM) extrusion technology for the manufacture of high-performance composites

<abstract> <p>The composites industry is present in practically all industrial sectors with an annual growth rate of 5%. Its contribution to the priority "light-weighting" driver transport sector key. The efficiency made possible by evolution manufacturing processes that also improve performance products obtained. For example, out-of-autoclave (OOA) can obtain high-performance such as those obtained autoclave process at lower costs. A key aspect development this type preforming continuous fibre reinforcements, which achieve high percentages while facilitating processing. Manufacturing these preforms currently requires multiple steps, equipment and tooling. TECNALIA's work developing ADDICOMP technology, alternative preform method using additive based on Fused Deposition Modelling (FDM) detailed article. This patented Tecnalia was conducted 2 phases: (a) filaments coated polymeric material printable FDM (b) fine-tuning technology print a very content fibre.</p> </abstract>
