    Abstract

    Utilisation of composite materials in the fabrication of13; high performance pressure vessels like solid propellant rocket motor cases presents a unique problem which is characteristic of composite materials. For the optimal design of motor cases, it is necessary to use high design stresses. As the motor cases are normally filament wound, embedding high strength fibres in a resin matrix whose strength and percentage elongation at failure are very much lower than that of the fibres, cracking of resin matrix take place under stress, at a stress value13; very much below the design stress. Hence, in order to utilise, the high specific strength of the fibres in filament wound pressure vessels, it becomes necessary to provide a 'barrier' or liner on the inner surface of the vessel to contain the pressurizing medium.
