Containment structure

摘要

A circumferentially extending structure 30 for containing particles having an axial component and a radial component of velocity is disclosed. The apparatus is comprised of a hollow annular beam 48 and a fabric 46 wrapped under tension about the annular beam such that the installed length of the fabric is greater than the free length of the fabric. In one particular embodiment the fabric is coated with a layer 116 of epoxy resin such that the resin penetrates only the top layer of the fabric to form a shield. The shield layer protects the containment fabric from injury.
