FABRICATION AND TESTING OF FLEXURAL PROPERTIES OF GLASS FIBRE EPOXY SKIN PIR 250 RIGID FOAM CORE SANDWICH COMPOSITE MATERIAL

This study aims to enhance the flexural properties of sandwich composites made from glass or carbon face and glass and carbon fibre Z-pin inserted extruted-polystyrene (XPS) foam cores. Carbon and glass pins were placed through XPS foams with two different column and row densities (15 and 30 mm). Results indicated that flexural loads, strength and modulus of glass/XPS and carbon/XPS sandwich composites significantly increased after inserting of glass and carbon rods. Core shear strengths and facing stresses of glass/XPS and carbon/XPS increased by increasing of carbon or glass rod densities. The rod type, rod density and face type of the sandwich composites are considered as significant parameters which affect the flexural behaviour of sandwich composites while using carbon rods enhanced flexural properties more than that of using glass rods due to better interfacial bonding.

ABSTRACTIn the present study a new sandwich laminate is designed and mechanically characterized. The laminate is elaborated with a core of particulate composite material consisting of recycled material from milk and juice cartons (multilayer laminate of Tetra Brik®), and HDPE containers from Urban Solid Waste (USW). The elaborated material consists of aluminum facings with a particulate core, consolidated with a thermoplastic adhesive of polypropylene- maleic anhydride. The main properties under tension are evaluated under testing standards. Results show good compatibility in the union of elements, with potential applications in building facades and false walls for the construction and furnishing industries.

Glass Fibre Reinforced

In this experimental study, the tensile behaviour of bolted joints of pultruded glass fibre reinforced polyester sandwich composites was investigated. The transverse specimens cut normal to the pultrusion direction failed by net-tension whereas the longitudinal specimens cut parallel to the pultrusion direction failed by a combination of bearing and shear-out modes. The joint strength was dependent on the specimen geometry in the case of transverse specimens whereas it was not in the case of longitudinal specimens.
