An experimental program is presented which examines the microfracture in the damaged zone near the notch root of FRP plates. This is accomplished by observation of the damaged zone in notched plates of a glass fiber-reinforced polycarbonate under tension. The process of initiation and growth of damage was measured by means of the luminance measurement technique with a CCD camera during loading and unloading in tension tests. Closer observation on the cracks on the notch root surface revealed that numerous microcracks initiated on the notch root at the early stage. Several microcracks joined together and grew into a crack. The process of initiation and growth of the microcracks produced the decline of luminance near the notch root.
