StratifiésIndex. décimale : 620.1 Mécanique de l'ingénieur (mécanique appliquée) et matériaux Résumé : Hybrid processes combining characteristics of prepreg and resin infusion/injection techniques are interesting and advantageous solutions for manufacturing of highly integrated structures. The possibility, given by traditional prepreg technology, to manufacture with a good reproducibility parts having elevated mechanical performances and as well to introduce additives like flame retardants or tougheners, can be successfully combined with liquid composite molding (LCM) characteristics. This work aimed to investigate these combined processes. The present research involved furthermore out-of-autoclave (OOA) prepreg, which provide additional cost-savings and environmental advantages compared with standard autoclave techniques: OOA prepreg plies and dry fabrics are laid up together in a mold and then resin is injected (RTM-like) or infused (VARI-like) in the cavity. When the impregnation is completed the part can be cured in oven. Goal of the investigation is to analyze the performances of hybrid laminates, in respect to pure OOA prepreg- and LCM-parts and to optimize the manufacturing route, assessing the process robustness through several tests. Simple demonstrators have been also realized to prove the hybrid technique feasibility and effectiveness.

Hors autoclave (technologie)Index. décimale : 668.4 Plastiques, vinyles Résumé : In the on-going commitment to reduce weight even further in automotive structures, many OEMs and suppliers are focusing on implementing the best and most cost-effective processing techniques to manufacture mass-produced, epoxy composite vehicle parts. Here, Klaus Ritter, Head of the Centre of Excellence for Composites at Huntsman Advanced Materials, looks at how the company is helping to optimise the latest out-of-autoclave manufacturing techniques, working to match demands for excellent component properties with shorter production cycles in mass production. Huntsman Advanced Materials has a long heritage of pioneering technologically advanced epoxy systems. In the automotive sector, the company's unrivalled legacy of technical innovation and epoxy composites applications spans from the super car market to structural applications on luxury marques and more recently, mass-produced vehicle parts.

Hors autoclave (technologie)Index. décimale : 620.1 Mécanique de l'ingénieur (mécanique appliquée) et matériaux Résumé : Fibre-reinforced polymer composites are increasingly considered for replacing metals in high-temperature-resistant components for aircraft and helicopters. With very limited resin options available to manufacture such composite components, Henkel and luickstep studied a Loctite benzoxazine resin offering high glass transition temperatures and excellent hot/wet performance, combined with room temperature storage and easy processing, to develop an energy-efficient and manufacturing-friendly out-of-autoclave (0oA) process.

PolymérisationIndex. décimale : 668.4 Plastiques, vinyles Résumé : Weight savings and volatile organic emissions reduction are issues often debated nowadays in the transport sector. The goal of aircraft manufacturers is to achieve green aircrafts, which means to invent innovative ways to make aircraft clean by reducing their air pollution and fuel consumption and improving their efficiency. In this context, composite materials play a significant role in the current and the future aircraft industry due to their exeptional strenght and stiffness-to-density ratios, which contribute to weight reduction.

ThermodurcissablesIndex. décimale : 668.4 Plastiques, vinyles Résumé : This paper describes the development of electrically-heated ceramic composite tooling, aimed primarily at the manufacture of large composites structures, for aerospace or for wind energy. The tooling is designed to operate at temperatures up to 300°C, but has the potential to be used at temperatures up to 500°C and above. The ceramic material is an aluminosilicate material, reinforced by continuous fibres and thermoplastic polymer, and laid up with embedded electrical heaters. The ceramic and reinforcing layers are laid up by hand at room temperature, on a standard pattern and cured initially to 60°C, followed by a free-standing post-cure, in stages to approximately 400°C. Special-purpose gel-coats and surface sealing layers are employed to ensure a smooth, vacuum-tight surface. The tooling is lightweight, strong and durable, and has a low coefficient of thermal expansion. Electrical heating power per square metre of tool surface is typically between 5.0 and 15.0 KW/sq.m. Examples are given of the use of the tooling to manufacture 12.6 metre long glass-fibre/epoxy and glass-fibre/PBT wind turbine blades (250KW machine). Aerospace carbon-fibre epoxy prepregs are also processed on the tooling successfully. In all cases, the materials need to be processed between 180°C and slightly above 200°C. The integrally-heated ceramic composite tooling provides a more cost-effective tooling system for processing thermoplastic or thermoset composites at these temperatures than standard metal tooling.
