“…There have been many studies on manufacturing plastic automobile parts using injection molding mainly using polypropylene (PP) and polyamide 6 (PA6)-based materials [4][5][6][7][8][9][10]. Whiteside et al predicted the fiber orientation distribution of a clutch pedal made with glass fiber reinforced PA6 by using simulation software and confirmed that the distribution matched the experimental results [4].…”

Shrinkage and warpage of injection-molded parts can be minimized by applying microcellular foaming technology to the injection molding process. However, unlike the conventional injection molding process, the optimal conditions of the microcellular foam injection molding process are elusive because of core differences such as gas injection. Therefore, this study aims to derive process conditions to minimize the shrinkage and warpage of microcellular foam injection-molded parts made of glass fiber reinforced polyamide 6 (PA6/GF). Process factors and levels were first determined, with experiments planned accordingly. We simulated designed experiments using injection molding analysis software, and the results were analyzed using the Taguchi method, analysis of variance (ANOVA), and response surface methodology (RSM), with the ANOVA analysis being ultimately demonstrating the influence of the factors. We derived and verified the optimal combination of process factors and levels for minimizing both shrinkage and warpage using the Taguchi method and RSM. In addition, the mechanical properties and cell morphology of PA6/GF, which change with microcellular foam injection molding, were confirmed.

Otomotiv endüstrisi geçtiğimiz yüzyıl boyunca önemli ve kayda değer gelişim sergileyerek günümüzde insan hayatının en vazgeçilmez öğelerinden biri haline gelmiştir. Başlangıçta sürücü ve yolcuları dış ortamın etkilerinden korumak için kullanılan camın birçok araştırmanın konusu haline gelmesi ile özellikleri değiştirilmiş ve bu sayede uygulama alanları genişletilmiştir. Ayrıca, üretim teknolojilerinin de izin vermesi ile birlikte camsı karakterde farklı malzemeler de otomotiv endüstrisinin bileşenleri arasına girmiştir. Mevcut çalışmada camın ve camsı malzemelerin geçmişten bugüne otomotiv endüstrisindeki yeri incelenmiş, çeşitli uygulama ve geliştirme çalışmalarından örnekler sunulmuştur.

In this paper, an integrated method for the design of suspension components with lightweight materials is proposed. Starting from the well-established design flow for chassis components, the paper analyse the manufacturing and design aspect which are mutual dependent in composite structures, providing technical guidance. The proposed design methodology is applied to an innovative suspension archetype patented by Magneti Marelli, F.L.E.C.S. (Flexible Link Elevated Compliance Suspension). First, an analysis of available lightweight material is carried out to define which one best fits the design requirements in terms of density, stiffness, cost and manufacturability. Second, structural simulations, based on finite element analysis, are performed to investigate the influence of the thickness and material on the elasto-kinematic performance of the suspension. According to the stress distribution, an optimization of the shape and the stacking sequence of the component is performed. The results show that 8.5 mm carbon fibre reinforced epoxy is the best solution for the blades, and 5 mm aluminium alloy for the reinforcement tube wall thickness. Third, with respect to the final design, an adhesive interface is analysed and designed, using the Goland-Reissner model.
