plication of composite
materials in airplane structure , and make it possible to further lighten the structural weight of the airplane , improve its fatigue property as well as reduce manufacture cost. This paper focuses on the design , analysis and experiment of an in2plane rounding type laminated composite joint. The engineering design plan and the theoretical analysis are presented and the strength prediction expression at dangerous spots of the joint is derived. The loading capacity of the specific joint is then predicted. A static experiment of the in2 plane rounding type laminated joint is carried out , the result of which agrees with the theoretical prediction. The research is useful for engineering reference and application of composite structure technology in large air2
