MAXIMUM ERROR LIMIT AND MINIMUM SPECIMEN NUMBER REQUIRED IN STRENGTH AND FATIGUE TESTING OF COMPOSITES
Large sample size is required in strength and fatigue testing of composite materials because of their big experimental data scatter. The variational coefficient, Cv,of CFRP,for instance,is 8 to 11 percent for strength tenting and 14-16% for fatigue.The experiment cost of these two properties may be very high if the reliable experimental results is required.
