• Note (General): This report describes the influence of impact damage on the compressive strength of CFRP (Carbon Fiber Reinforced Plastics) -laminated panels. The panels with impact damage are subjected to compressive loads for evaluation of their residual strength. The interlaminar failure of the panels with impact damage is investigated using ultrasonic inspection techniques and optical microscopy. The test results are summarized as follows. The area of delamination on the reverse surface is larger than that on the impact surface. The shape of the area is an ellipse whose major axis corresponds to the fiber direction of the surface laminate. In addition, the area size is approximately proportional to the impact energy. The compressive residual strength decreased with increasing impact damage. The compressive residual strength with impact damage of 70 J/cm is reduced to about 75 percent of the strength without impact damage.; 資料番号: AA0004267000; レポート番号: NAL TR-1260
