[article]  inJEC COMPOSITES MAGAZINE > N° 88 (04/2014) . - p. 66-69 Titre : Correction of manufacturing induced distortions of automotive composite parts with simulation Type de document : texte imprimé Auteurs : Mathilde Chabin, Auteur ; David Prono, Auteur Année de publication : 2014 Article en page(s) : p. 66-69 Langues : Anglais (eng) Catégories : Automobiles -- Matériaux Calcul Composites à fibres Contraintes résiduelles Déformations (mécanique) Fibres continues Matières plastiques dans les automobiles Procédés de fabrication Simulation par ordinateur Thermodurcissables Tolérance (technologie) Index. décimale : 668.4 Plastiques, vinyles Résumé : One of the biggest challenges for designers and mnaufacturers of composites-parts nowadays is to ensure that designed parts can be produced within tolerance that will cause no issue at the assembly stage. This paper that focuses on automative applications of composite materials for structural parts will first review adapted manufacturing processes for mass production and then describes involved physics in resulting shape distortions. Computational techniques developed to predict manufacturing-induced residual stresses and shape distortion of composites parts made of continuous fibers and thermoset matrix will be presented supported by an industrial example. Knowing how the part will distort after manufacturing is a first step. The second one consists in finding a solution to these geometrical defects in regards to the designed part. Simulation can then be of a great help in determining the proper process parameters and new mold geometry to reach tolerances. However this paper intends to demonstrate that only the simulation of the complete manufacturing chain can validate a solution to distortions.

Making SMC decisions at an early design phase / Mathilde Chabin in JEC COMPOSITES MAGAZINE, N° 134 (05-06/2020)

[article]  inJEC COMPOSITES MAGAZINE > N° 134 (05-06/2020) . - p. 30-31 Titre : Making SMC decisions at an early design phase Type de document : texte imprimé Auteurs : Mathilde Chabin, Auteur ; Sebastian Muller, Auteur ; David Prono, Auteur Année de publication : 2020 Article en page(s) : p. 30-31 Langues : Anglais (eng) Catégories : Composés de moulage en feuille Composites Conception technique Design industriel Simulation par ordinateur Systèmes d'aide à la décision Index. décimale : 668.4 Plastiques, vinyles Résumé : What are the most important things when considering the use of composite materials for lightweight industrial applications ? The first selection criteria are overall costs, process automation, repeatibility and production rates. Sheet Moulding Compound (SMC) is a very good candidate in these regards. However, it is crucial for an engineer to be able to make design decisions at an early stage of product development. This article presents an innovative approach addressing this challenge to allow further industrial and optimized use of SMC.
