Abstract

Within this paper, three types of composite laminates have been subjected to four-point bend tests using the resistive stress analysis: 4 layers epoxy reinforced chopped strand mat of 450 g/m2 specific weight (denoted epoxy/4CSM450), 4 layers epoxy reinforced glass roving fabric of 800 g/m2 specific weight on warp direction (denoted epoxy/4RT800U) and 4 layers epoxy reinforced glass roving fabric of 800 g/m2 specific weight on weft direction (denoted epoxy/4RT800B). Between these layers, three strain gages have been applied and connected to a Spider8 device. Distributions of load versus time as well as specific deformation versus time for all three types of composite laminates have been experimental determined in four-point bend tests using the CATMAN software..
