Abstract:

Present rocket motor cases are being made with Type E commercial glass fibers because of the relative ease of manufacture, high resistance to weathering, strength and low cost. Processing improvements are considered the best immediate means to physical improvements. Some improvement in the modulus of elasticity of Type E glass is possible by modified and improved manufacturing processes, but this may be accompanied by a loss in strength. Significant improvement in the modulus will create new problems in the glass bonding with plastics. The most effective additive for improving the glass modulus is BeO. Continuous filament glass fiber of this type is available, but expensive and difficult to manufacture. While increased modulus of elasticity is needed in fiber glass, only a fraction of this increase can be realized in the bulk modulus of the structures made from the fibers.
