Abstract

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 in the transport sector is key. The efficiency of the industry is made possible by the evolution of manufacturing processes that also improve the performance of the products obtained. For example, out-of-autoclave (OOA) processes can obtain high-performance composites such as those obtained by the autoclave process at lower costs. A key aspect in the development of this type of process is the preforming of continuous fibre reinforcements, which can achieve high fibre percentages while facilitating processing. Manufacturing these preforms currently requires multiple steps, equipment and tooling. TECNALIA's work developing the ADDICOMP technology, an alternative preform manufacturing method using an additive process based on Fused Deposition Modelling (FDM) is detailed in this article. This development is patented by Tecnalia and was conducted in 2 phases: (a) development of continuous fibre filaments coated with polymeric material and printable by FDM and (b) fine-tuning of FDM technology to print filaments with a very high content of continuous fibre.
采用增材熔融沉积(FDM)挤压技术制备高性能复合材料预制体
复合材料工业几乎存在于所有工业部门,年增长率为5%。它对交通运输领域优先“轻量化”驱动的贡献是关键。工业的效率是通过制造工艺的发展而实现的,制造工艺也提高了所获得产品的性能。例如,非高压灭菌器(OOA)工艺可以以较低的成本获得高性能复合材料,例如通过高压灭菌器工艺获得的复合材料。这类工艺发展的一个关键方面是连续纤维增强的预成型,它可以在促进加工的同时实现高纤维百分比。目前,制造这些预成形件需要多个步骤、设备和工具。本文详细介绍了TECNALIA开发的ADDICOMP技术,这是一种使用基于熔融沉积建模(FDM)的添加剂工艺的预制体制造方法。这项开发由Tecnalia获得专利,分两个阶段进行:(a)开发涂有聚合物材料并可通过FDM打印的连续纤维长丝;(b)微调FDM技术以打印具有非常高含量连续纤维的长丝。
