ABSTRACT	This report describes the influence of impact damage on the compressive strength oaf CFRP-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 sth increasing impact damage.The compressive residual strength with impact damage of 70J/cm is reduced to about 75％ of the strength without impact damage.
