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.

“…The numerically determined orthotropic properties using Strain energy-based homogenization technique can be successfully used for generating an equivalent solid of a honeycomb core which ultimately can be used for performing 3PBT on sandwich panel to determine the deformation and stiffness of a sandwich panel. For producing representative volume element (RVE) of a core, only a single cell can be selected and homogenization technique instead of selecting a entire core cells can be utilized which will result in considerably reduced computational time and effort 3,7,11) . Gibson and Ashbay initially determine the formulae for detection of nine orthotropic properties for honeycomb materials with constant wall thickness followed by the number of revisions by 'Zhang and Ashbey' and 'Klintworth and Stronge' to include the double wall thickness for the out of plane values using homogenization techniques.…”

The composite sandwich structures are in great demand in aircraft, automotive and sports industries because these materials possess light weight, high flexural strength and stiffness. In present research paper, initially a composite sandwich structure, having Carbon Fibre Reinforced Plastic (CFRP) face sheets and a regular hexagon Kevlar® Honeycomb core material, in the form of an equivalent solid, has been modelled. 'Gibson and Ashbey' model for regular hexagon double wall thickness honeycomb core has been employed to determine the equivalent orthotropic properties of Kevlar® Honeycomb core. "Three point bend test (3PBT)" has been performed on sandwich panel using Ansys as per ASTM C393-00 standard and ultimate load and deformation have been calculated. Then for experimental result, a composite sandwich has been fabricated and a 3PBT also has been performed on it. The analytical value for deflection has also been found using the ASTM C 399-00 standard. The value of stiffness obtained from finite element model is successfully compared with the experimental and analytical solutions and the numerical model predict to an excellent stage of the static behaviour of the material whilst compared with the experiments.

“…Nowadays, composite materials have been commonly used in many application areas such as aerospace, automotive, military and defence, and civil engineering [1][2][3][4][5][6], which depends on its superior stiffness, strength properties and higher flexural strength. Sandwich panel consists of two thin fibre reinforced plastics skins and the lightweight core structure.…”

It is a challenging task to manufacture the novel lightweight sandwich panel with different composite materials. The aim of this paper is to study the energy-absorbing characteristics of single spherical-roof contoured-core cell with carbon, glass and aramid fibre reinforced plastics, which were fabricated through compression moulding technique. The quasi-static compression test was carried out to investigate the compressive properties and crushing behaviour of the single contoured-core cell. It was demonstrated that the single spherical-roof contoured-core with aramid fibre reinforced plastic provided the highest specific energy absorption value of 0.69 kJ and the lowest compressive stiffness of 30.43 kN/mm compared to carbon and glass fibre reinforced plastics. Furthermore, it was observed that matrix cracks, fibre fracture and laminate bending are the main failure modes of the single contoured-core cell under quasi-static loading.
