In this paper we present the results of systematic investigations of interaction between high power near-IR laser beam and composite material samples composed of sandwich structures of structural composites of Fiber Reinforced Polymer. Sandwiches of carbon and glass fabric woven|/epoxy resin shells and foam core as well as carbon reinforced/epoxy laminate have been tested. The experiments are performed by means of high speed 3D digital image correlation and thermographic methods. The studies allow to estimate the symptoms and results of damage effects against composite material targets such as an UAV’s airframe shell.
