In this work, three different types of laminates, each one realized with thirteen layers of fabric in epoxy matrix, have been inspected. In the first one, only aramid fiber is used, whilst the other two are hybrid laminates reinforced with basalt and aramid fibers disposed either in an intercalated or in a sandwich-like structure. All laminates were impacted with an energy of 12.5J. Inspection of...
Abstract: In this work, the combined effect of indentation damage and of manufacturing defects of a hybrid laminate including jute hessian cloth (plain weave) and hemp fibres in an epoxy matrix has been investigated. With this aim, various non‐destructive evaluation (NDE) techniques have been employed, such as near‐infrared (NIR) reflectography, infrared thermography (IRT), holographic interferometry...
