At Composites Europe 2012, which takes place in Düsseldorf, Germany, from 9 - 11 October, 2012, Dieffenbacher, Hennecke, KraussMaffei, and Siempelkamp will be present, not only as exhibitors, but also in arranging the Composites forum in which lectures will be presented in topic-specific workshops and exhibitor presentations and are designed to inform visitors about the basic trends and innovations in composites.
The programme that has been set up with the assistance of the VDMA focuses this year on the topic of "automation". Under the heading "Process stages towards mass production", the VDMA Composite Technology Forum will chair presentations on the topic. All presentations will be given in English.
On the first day, Matthias Graf, Technical Manager at Dieffenbacher, will host CFRP-Preformtechnology - advancements in the fully automated preform process for complex parts. Dieffenbacher has developed a Preform Centre for the fully automated production of 3D preforms from carbon fibres. With it, it claims short cycle times are achievable during preform production. From the supply of the semi-finished textile of carbon fibre via the precise cut and application of the binder to the provision of the dry, dimensionally stabile 3D preform, the complete process runs fully automatically and with a reliable handling technique. The plant concept stands out due to its simple, modular design and is aimed at flexible use for large and small scale production of tailor-made preforms.
On the next day, Jens Winiarz, Sales Manager at Hennecke, will presemt the topic "High Pressure meets lightweight". The machine builder has developed a process engineering approach, which provides a response to the constantly growing demands where efficiency and ecology are concerned in the automotive sector. Compared with the classic RTM process, Hennecke says the new technology features a rapid injection of the reactive mixture into the cavity. This ensures extremely brief curing times and thus guarantees cycle time optimisation throughout the process. High quantities can be suitably achieved.
The RTM process is also the topic of the presentation by Erich Fries, Composite Business Unit Manager, and Sebastian Schmidhuber, Lead Engineer R&D, at KraussMaffei. They will be talking about "high-performance fibre composite parts - manufactured in an economically efficient way." For example, the company has developed a modular concept, which illustrates the production of a CRP component in the HP-RTM process (high pressure - resin transfer moulding) with all operating stages over the complete process chain. This starts when assembling the fibres and producing the dry fibre preform, which is placed in a tool specially developed and produced by KraussMaffei. The concept utilises proven components and the benefits from mass production with injection moulding machines with which to develop application specific solutions.
"Siempelkamp press technology for high end composite production" is the title of the presentation to be given at the Forum by Dr Michael Schöler, Research and Development Manager at Siempelkamp. The company produces handling systems and presses, with which sandwich composites can be produced automatically, for example rotor blades for wind power stations, whose half shells are currently still being stuck together by means of arduous manual work. The core material and the covering layer are combined and stuck together with these systems. Siempelkamp offers here both continuous as well as discontinuous processes.
Apart from the stated presentations, numerous well-known speakers, companies and institutions, including Dassault Systems, Mapal and CFK Valley Stade will contribute additional topics. The event is supported by the industry magasine "Reinforced Plastics".
Composites Europe explains that it has established a Product Demonstration Area (PDA), which has developed in recent years into its number one visitor attraction. Exhibitors present live demonstrations of their new products and processes and visitors can experience how innovations are developed.
BÜFA will present the production of a GRP component in vacuum assisted RTM (VARTM) with the aid of the fully automated metering unit BÜFAtec RTM. IKV Aachen intends to present 3D fibre spraying with thermoplastic hybrid yarns. With this process, three-dimensional near-net-shape preforms can be produced with locally adjustable characteristic profiles such as thickness or fibre orientation. RH Schneidtechnik displays at the special display area the automated cutting of composite materials. The Institute of Lightweight Engineering and Polymer Technology of TU Dresden is represented at the Product Demonstration Area with textile-reinforced composite materials.
Wabash and Carver will highlight their composite moulding presses at the SAMPE 2018 Conference & Exhibition on 23-24 May in Long Beach, California, US.
Attwater has invested £100,000 in two new CNC machines.
Sharp & Tappin has installed and commissioned one of its Compcut 200 advanced composite saws at SHD Composites in Sleaford, Lincolnshire, UK.
