Composite shell

摘要

A thin-walled annular shell of high rigidity relative to its unit weight is provided. The wall of the shell is a composite material built up layerwise of glassy alloy strips of high transverse aspect ratio such that each layer is a strip wrapped at a substantially 45 DEG helix with respect to the elongate axis of the shell and with adjacent layers having alternating directions of wrap. Bonding between adjacent layers and between strips within each layer is accomplished in a selected manner such that the composite wall is structurally monolithic for thin-walled applications thereby taking substantially full advantage of the extraordinary strength properties of glassy alloy strip.
