From a niche product to standard series production / Christian Götze in KUNSTSTOFFE INTERNATIONAL, Vol. 106, N° 3 (03/2016)  

[article]  inKUNSTSTOFFE INTERNATIONAL > Vol. 106, N° 3 (03/2016) . - p. 35-38 Titre : From a niche product to standard series production : resilient lightweight components produced from organo sheet Type de document : texte imprimé Auteurs : Christian Götze, Auteur Année de publication : 2016 Article en page(s) : p. 35-38 Langues : Anglais (eng) Catégories : Composites à fibres -- Moulage par injection Composites à fibres -- Thermoformage Composites à fibres de verre Matériaux -- Allègement Matières plastiques dans les automobiles Polyamide 6 Index. décimale : 668.4 Plastiques, vinyles Résumé : The processing of organo sheet into lightweight structural components featuring high strength and rigidity is now ready for standard series production. This fact is exemplified by the production of a seat pan for a sports car in a fully automated production cell. The shell consists of blanks cut from organo sheet, onto which are molded reinforcing ribs, fastening elements and a glass fiber-reinforced plastic edging surround.

Having a good grip on hot laminates / Christian Götze in KUNSTSTOFFE INTERNATIONAL, Vol. 106, N° 9 (09/2016)  

[article]  inKUNSTSTOFFE INTERNATIONAL > Vol. 106, N° 9 (09/2016) . - p. 94-97 Titre : Having a good grip on hot laminates : UD tape reinforcement minimizes weight while maximizing local loading capacity Type de document : texte imprimé Auteurs : Christian Götze, Auteur ; Philipp Böhme, Auteur ; Bert Rietman, Auteur ; Emmanuel Boxus, Auteur ; Stefan Fenske, Auteur ; Stefan Schierl, Auteur Année de publication : 2016 Article en page(s) : p. 94-97 Langues : Anglais (eng) Catégories : Adhésion Anisotropie Composites à fibres -- Moulage par injection Composites à fibres -- Propriétés mécaniques Composites à fibres -- Surmoulage Fibres à orientation unidirectionnelle Fibres continues Matériaux -- Allègement Stratifiés Traction (mécanique) Index. décimale : 668.4 Plastiques, vinyles Résumé : A recently developed variant for processing continuous fiber-reinforced semi-finished products by injection molding, involves positioning a defined number of UD laminates appropriate to the specific requirements in the mold and then overmolding them. The resultant lightweight, three-dimensional parts have rigidity and strength which are markedly anisotropic and optimized for their particular loading situations. Note de contenu : - Taking material savings to the max - Demonstrator component reveals application potential - Heated UD laminates pose engineering challenges - Manufacturing skills combine to obtain molding - Tested and found suitable for mass production - FIGURES : 1. Demonstrator component with three UD laminate inlays of different dimensions. In the demonstrated cross-section (bottom) the inlays are colored in green - 2. For Transferring the laminates into the mold, KraussMaffei developed a specially optimized gripper system and also integrated - 3. Using the production cell completely installed by KraussMaffei, the demonstrator part could be manufactured with a cycle time of under 60s - 4. GKTool designed and built the mold for manufacturing the dmonstrator part and punch and matrix - 5. The results from the filing simulation match well with the filling study performed - 6. Depending on how the cavity fills with melt, the clamping elements can be separately retracted - 7. The comparison between simulation and the 4-point bending reveals a good match and thus the high quality of both the calculation and the component produced. The failure point under tensile (laminate on the underside) and compressive loading (laminate on the top side) is marked in red in each case Résumé: A recently developed variant for processing continuous fiber-reinforced semi-finished products by injection molding, involves positioning a defined number of UD laminates appropriate to the specific requirements in the mold and then overmolding them. The resultant lightweight, three-dimensional parts have rigidity and strength which are markedly anisotropic and optimized for their particular loading situations.

Production cell for the fully-automated manufacture of a lightweight seat pan made of organo-sheet with moulded-on reinforcing ribs - 3. Prototype of a car side impact protection component. No creases should form during the thermoforming of the organo-sheet - 4. Different versions of a door trim part produced from different organo-sheets in an experimental mould - 5.
