Abstract : As far as impact damage mechanisms with regard to free ARALL and two types of prestressed ARALL laminates are concerned, surface observations and test measurement analysis without damage were carried out with respect to the propogation of impact damage during fatigue processes. Cumulative fatigue damage models were set up for laminates after impact. Probes were done with regard to the influences of prestressing on fatigue properties after ARALL laminate impact. (MM)
