Abstract

Abstract: In order to ensure the internal quality of the composite shell with both ends reduced, the method of lap spiral winding and inflatable bladder was used to prepare the composite shell. The bonding parameters were determined by testing the performance of the bonded inclined tape through experiments. The winding mode of the inclined tape was designed and the deformation of the inclined tape was calculated to determine the winding parameters. Different pressures were selected for experiments and tests, and the quality of samples was compared. The results show that the preferred bonding time of the inclined tape is 1 s, the bonding temperature is 80~90 ℃, the maximum deformation of the inclined tape is controlled at about 10 mm during winding, and the pressure of the bladder is 3 MPa, the internal quality of the prepared inner insulated shell is the best.

Key words: inflatable bladder molding, tape winding, composite materials
