The present invention relates to a system and a method of non-contact and non-destructive inspection to detect a defect in a composite material. More specifically, the system for non-contact and non-destructive inspection comprises: an acoustic device including a sound wave oscillating portion oscillating sound waves, and a sound focusing portion to focus sound waves oscillated from the sound wave oscillating portion to excite sound waves into the composite material to be inspected to vibrate the composite material; an infrared thermography camera to photograph infrared thermography of the composite material; and an analysis means to analyze a defect of the composite material by analyzing thermography photographed from the infrared thermography camera. 본 발명은 복합재료 결함 검출을 위한 비접촉 비파괴 검사시스템 및 검사방법에 대한 것이다. 보다 상세하게는, 비접촉 비파괴 검사시스템에 있어서, 음파를 발진시키는 음파발진부와, 상기 음파발진부에서 발진된 음파를 집속시키는 음집속부를 구비하여, 검사대상이 되는 복합재료에 음파를 가진하여 상기 복합재료를 진동시키는 음향장치; 상기 복합재료의 적외선 열화상을 촬상하는 적외선열화상카메라; 및 상기 적외선열화상카메라에서 촬상된 열화상을 분석하여 상기 복합재료의 결함을 분석하는 분석수단을 포함하는 것을 특징으로 하는 복합재료 결함 검출을 위한 비접촉 비파괴 검사시스템에 관한 것이다.
