Composite materials ready to replace aluminium in internal combustion engines / Hendrik de Keyser in JEC COMPOSITES MAGAZINE, N° 102 (01-02/2016)

[article]  inJEC COMPOSITES MAGAZINE > N° 102 (01-02/2016) . - p. 32-35 Titre : Composite materials ready to replace aluminium in internal combustion engines Type de document : texte imprimé Auteurs : Hendrik de Keyser, Auteur ; Lars-Fredrik Berg, Auteur ; Jannik Stammler, Auteur Année de publication : 2016 Article en page(s) : p. 32-35 Langues : Anglais (eng) Catégories : Composites à fibres de carbone Composites à fibres de carbone -- Moulage par injection Coût-Efficacité Matériaux -- Allègement Matières plastiques dans les automobiles Motocyclettes -- Moteurs -- Pièces Phénoplastes Index. décimale : 668.4 Plastiques, vinyles Résumé : In the next 3-5 years, the first cylinder housings manufactured from polymer composite materials could be introduced into passenger car and motorbike engines, replacing the aluminium components currently in use. Glass fibre-reinforced phenolic cylinder housings manufactured by injection moulding deliver the same performance as die-cast aluminium components but offer a significant reduction in weight, lower manufacturing costs and a better life cycle assessment. Additional benefits include reduced heat radiation, lower engine noise emissions and the elimination of corrosion-related issues. Note de contenu : - A range of candidate materials - Demonstrator cylinder housing - Performance benefits - Weight and cost savings - Reduced environmental impact - Building confidence in composites - FIGURES : 1. SBHPP has developed a phenolic composite cylinder housing for a single-cylinder 650 cc engine that demonstrates a significant weight reduction over the aluminium part, as well as lower manufacturing costs - 2. The composite cylinder housing showing the metal inserts and liner - 3. The injection moulding machine for the composite cylinder housing - 4. Weight comparison figures for cylinder housings manufactured from different materials - 5. Cost analysis for the composite cylinder housing compared with the aluminium part - 6. Comparison of the energy required to produce various materials, and the energy required to produce a component with equal stiffness to steel Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=25447 [article]
