Motocyclettes -- MatériauxIndex. décimale : 668.4 Plastiques, vinyles Résumé : It all began in a garage where the nucleus of the U.S. company German Advanced Composites, Inc. was born. Originally started as a private project, FastForward, a custom motocycle based on an air- and oil-cooled, 4-cylinder in-line engine with 1200 cm³ and 178 hp turned out, over a period of 9 years, to become a lesson in the matter of "How to build perfect carbon fibre parts".

Moulage par transfert de résine sous videIndex. décimale : 668.4 Plastiques, vinyles Résumé : Along with several partners, Hennecke developed a process to produce complex-geometry hollow HP-RTM parts combining epoxy or PU resin systems with woven or sheet carbon fiber materials. The process uses a sand core that can withstand pressures up to 200 bar and is held together by a binder. This binder is eco-friendly and can be flushed out with regular water and without any solvents. Even better, the core material is 98% recyclable. Note de contenu : - HP-RTM technology

PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.Index. décimale : 668.4 Plastiques, vinyles Résumé : As race car wiring is becoming more and more complex, power units are made up of several parts that need to be integrated into the final assembly. The available space being increasingly limited, engineers frequently use flexible parts such as cooling ducts and wiring harnesses. The motorbike solution outlined in this paper can be easily applied to the automotive racing world. Note de contenu : - First prototype

PolyuréthanesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Aerospace and racing without high-performance applications of fiber-composite structural parts have become unimaginable. Integrally manufactured hollow parts achieve top lightweight quality in those fields. Future mass production of complex hollow fiber-composite parts on an industrial scale required that a decisive step had to be taken in order to automate the HP-RTM process. Note de contenu : - The cavus production process
- Ideas for a functional and process-ready design
- Part and process simulation
- Sand core production via core shooting
- Preform production with hardly any clippings
- Polyurethane matrix within a short cycle time
- Parameters for the project
- High requirements for moldd technology
- New type of sealing material
- Result: almost two thirds lighter
- Further developments in the R.A.C.E project
- Fig. 1. ln the R.A.C.E. project based on the Cavus technology, a license plate holder was developed for the KTM Superduke 1290R motorcycle as a demonstrator part for mass production
- Fig. 2. Cavus production cycle (clockwise from the left) : The (e.g., additively produced) sand core is braided with carbon fibers and afterwards infiltrated in the mold in the HP-RTM process. Once solidifie & the core is removed using water
