Abstract : During the continuation of the first year's effort on forming shaped and hollow glass filaments, the process was refined. Precision windings were made to obtain close packing from rectangular microtape, both solid and hollow, while hollow hexagonal fiber was wound into a micro-honeycomb. Substantial mechanical properties data were developed on 2.3 in. diameter tubes precision wound from solid microtape into 90% by volume glass structures. These displayed no room temperature permeability to water and modulus of elasticity values the same as the glass; namely, 1,000,000 psi. Axial strengths of the tubes with only circumferential windings were as high as 25,000 psi. (MM)
