ITA's new induction heated glass fibre production line
At the joint stand of the Aachen Centre for Integrative Lightweight Construction (AZL), the Institut für Textiltechnik of RWTH Aachen University (ITA) will demonstrate its expertise in the field of glass fibres, preforms and textile concrete. The exhibits come from various fields of application and address the automotive, aerospace and mechanical engineering sectors. A short preview:
Innovative glass fibre research at ITA
The newly constructed induction heated glass fibre production line enables increased flexibility in research. For the first time, glass fibres will be produced live at the ITA booth at JEC World. One of the innovations of the system is the inductively heated bushing. It features a flexible design and consists of a platinum/rhodium alloy (Pt/Rh20) for use in high-temperature glasses.
DrapeCube - Forming of textile semi-finished products
The DrapeCube offers a cost-effective design for the production of fibre preforms from textile semi-finished products. It is used in the production of preforms for prototypes and in small series and is suit-able for companies active in the production of fibre-reinforced plastics (FRP). In the production of FRP components, the preforming process defines a large part of the subsequent component costs.
Carbon fibre reinforced plastic (CFRP) preform
The CFRP preform consists of carbon multiaxial fabrics formed by expanded polystyrene (EPS) to optimise draping quality. Preforms of increased quality can be produced by gentle, textile-compatible forming with foam expansion. For the first time, foam expansion was used to form preforms in such a way that the draping quality is improved compared to classic stamp forming.
Embroidered preform with integrated metal insert
The 12k carbon fibre rovings are shaped into a preform using Tai-lored Fibre Placement (TFP) which is a technical embroidery pro-cess. For the further layer build-up, a fastener is not only integrated under the roving layers but also fixed by additional loops. The highly integrative preforming approach offers the possibility of reducing weight and process steps as well as increasing mechanical perfor-mance. In addition, it is possible to automatize the production of integrative preforms; interesting for the automotive and aerospace industries.
