【Abstract】 A model of Springer was devloped which describes the filament winding process of composite cylinders.The model relates the significant process variables such as winding speed,fiber tension,and applied temperature to the thermal chemical and mechanical behavior of the vomposite composite cylinder and the mandrel.Based on the model.a user friendly code was written which can be used to calculate (1)the temperature in the cylinder and the mandrel.(2)the degree of cure and viscosity in the cylinder.(3)the fiber tensions and fiber positions.(4)the stresses and strans in the cylinder and in the mandrel.and (5)the void diameters in the cylinder.更多还原
