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.Note de contenu : - Composites manufacturing processes adapted to mass production

Systèmes d'aide à la décisionIndex. 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. Note de contenu : - An innovative manufacturing simulation approach
- From full manufacturing history to product validation
- Targeting further accuracy for optimized SMC designs

These materials made of melt-processable resins are light, stiff, have an infinite shelf life, the potential for rapid process speeds, and excellent recyclability. They are also more lightweight than metallic materials, and offer more adaptable designs. Note de contenu : - Simulating the manufacturing process
