<p>The purpose of this study is to make observations of the behavior of fatigue damages at a CFRP surface. Matrixcracks called transverse crack, splitting and delamination in a CFRP are occurred under fatigue loading. Generally Ultrasonic Test (UT) and X-ray Test are used for CFRP inspection. However, it has been known that the inspection on a CFRP surface with UT is a task of extreme difficulty. And X-ray Test is expensive. So,we applied Fluorescent Penetrant Test to a woven CFRP surface with fatigue damages. As the result, matrixcracks are detected during the cyclic tensile test. In addition , it was also found that splitting in terms of woven CFRP were formed 45° direction cracks look like the edge of a saw.</p>
