Abstract :In this study, laminated sandwich composites consist of glass fiber reinforced polymer insert ignore into journalissuearticles values(GFRP); face-sheets insert ignore into journalissuearticles values(skins); and polyvinyl chloride insert ignore into journalissuearticles values(PVC); foam were bonded together via conventional hand lay-up method. The effect of fiber orientation insert ignore into journalissuearticles values(0/90 or +45/-45); was examined in terms of compression and flexural properties. Flatwise insert ignore into journalissuearticles values(FW); compressive test provided the core dominated properties and only 0/90 fiber-oriented samples were tested. When the average edgewise insert ignore into journalissuearticles values(EW); compressive strength of insert ignore into journalissuearticles values(0/90);GFRP/PVC and insert ignore into journalissuearticles values(+45/-45);GFRP/PVC sandwich composites were compared, both of them showed similar results. Core crushing, local bending, debonding and core shear were observed as the common failure modes in the sandwich structures under bending. In terms flexural response, the 0/90 fiber oriented GFRP skin slightly showed better strength values as compared with +45/-45 fiber-oriented structures. By considering the all-quasi-static tests, it can be concluded that 0/90 and +45/-45 fiber oriented GFRP skins exhibited similar performance and there was no significant superiority for any of them.
