Polybutylène téréphtalateIndex. décimale : 668.4 Plastiques, vinyles Résumé : Molds for orthoses are usually machined. That is not optimal – neither for the patient nor for the manufacturer. Within the scope of a study, Lehmann & Voss therefore investigated whether 3D printing is an alternative – both ecologically and economically. Note de contenu : - PET filament instead of PUR foam

Matières plastiques -- Propriétés mécaniquesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Additive manufacturing processes count as future-oriented manufacturing techniques. Numerous studies and award-winning demonstrators underline the interest of the industry. Nevertheless, up to now there are only a few plastic-based applications with significant quantities. Today, screw-based additive manufacturing is a solution for the economic and technical challenges and has the potential for series production. Note de contenu : - Using strand shapes to systematically influence anisotropy
- Why does 3D printing plastics need metal ?
- Automated production of hybrid parts
- Approach to analyze the mechanical properties
- Mechanical properties at an optimal level
- Figure : The bicycle frame (600 g, produced in 80 min) is printed directly onto a metal sheet. This combination unites the advan-tages of two worlds
- Fig. 1 : Increasing nozzle diameters have a positive effect on the anisotropy of mechanical properties in the part
- Fig. 2 : Test set-up : variothermal fixture in production area of a SpaceA manufacturing unit, temperature load cycle and test specimen geometry
- Fig. 3 : Maximum load at different insert temperatures.This demonstrates the strong bond between plastic and metal over a wide temperature range
- Fig. 4 : Force-deformation chart of the tested specimens. The hybrid structure increases the stiff¬ness and strength compared to plastic-only test specimens
- Fig. 5 : Testing of the hybrid part: initial position (force applied to the metal component on the left, force applied to the plastic component on the right), maximum deflection of the test specimen and failure with fracture mode (insert temperature 175°C)
- Fig. 6 : Test in starting position (force application to the plastic component), maximum deflection of the test specimen and failure with fracture mode (insert temperature 220°C)

Titre : 3D reinforcement and delamination resistance Type de document : texte imprimé Auteurs : L. Hamitouche, Auteur ; M. Tarfaoui, Auteur ; A. Vautrin, Auteur Année de publication : 2006 Article en page(s) : p. 42-45 Langues : Anglais (eng) Tags : 'Modèle zone cohésive' 'Propriété mécanique' Modélisation 'Fibre minérale' 'Etude expérimentale' 'Construction navale' Application traction' 'Renforcement verre' 'Matériau renforcé fibre' 'Vinylester résine 'Méthode élément fini' 'Simulation numérique' aiguilleté' Optimisation 'Tissu textile' Stratifié composite' Délaminage fibre tridirectionnelle' Index. décimale : 668.4 Plastiques, vinyles Résumé : Delamination is the most critical damage mode for composite laminates. Many studies have been carried out on assemblies made with two-dimensional fabrics Even after optimisation, these assemblies do not meet the requirements for severe stresses from blast effect failing too easily due to delamination between two plies of 2D fabric. The present study deals with two aspects: 1) optimising the material properties of textile preform assemblies for shipbuilding applications through the use of stitched solutions for better delamination resistance; and 2) developing a numerical model based on cohesive zone mechanics that is capable of describing the deiamination process. The study was carried out in quasi-static conditions and the model implemented in the form of a subroutine within an implicit finite element code. Note de contenu : - Experimental study
- Mechanics of the cohesive element
- Validation of the cohesive modelPermalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=13930
