	The study is characterized low-energy and velocity impact resistance of classic carbon fiber reinforced oolvmer (CFRP) and hybrid laminates based on aluminium alloys connected witfi carbon/epoxy composite (Al./CFRP) composites. 1 ested laminates were prepared by autoclave method, which provides the best possible and repeatable quality of composites materials. Laminates were characterized in terms of a comparison of their impact resistance between tchem and according to different layers configurations or different energy levels. The laminates response to low velocity impact using hemispherical impactor (diameter 38.1mm) were analyzed. After tests, the failure was evaluated with using ultrasonic and microtomography methods. On this basis was determinate the nature of internal degradation of structure. It was noted, that used FML are innovative materials characterized by higher low-velocity impact resistance because of superior properties of both metals and fibrous composite materials with a strong adhesion bonding. Fiber-matrix interface is lowerdamage in FML in comparission to CFRP. Failure of tested fiber-metal laminat eis characterized by some transverse crack and metal-composite interface degradation in impact point area. It was noted that the moct common failure nature of both materials are interiaminar delaminations in impact point circumference zone.
