On the effect of glass and carbon fiber hybridization in fiber metal laminates: Analytical, numerical and experimental investigation

In the classical composites, the hybridization of carbon and glass fibers may cause a positive hybrid effect, which relies on the increase of carbon fibers failure strain, when compared to the pure carbon-based composites. This paper focuses on the investigation of the influence of the volume ratio of carbon and glass fibers hybridization in Fiber Metal Laminates, on the static tensile strain at which the laminate fails. Analytical, numerical and experimental studies have proven that the increase of carbon fibers failure strain occurs in the Fiber Metal Laminates and can be explained by the presence of thermal stresses caused by the manufacturing process at elevated temperature.
