SilvaAbstractThe aim of this study was to investigate the influence of the matrix properties, number of the carbon and aramid layers and fiber orientation on low velocity impact behavior of the fabric reinforced hybrid composites with stratified filled epoxy matrix. The impact tests were performed with the drop weight impact system at 90.629 J of energy level. The damage areas were analyzed by the visual inspection and tomographic images. The results showed that the matrix properties have a great influence over the fracture mode of the hybrid composites, while the fault degree of the damaged areas depends on the fiber orientation. The highest impact resistance was obtained in the case of hybrid composites with 0° ply orientation.
