Abstract
Abstract A lightweight strong cast for the repair of broken bones is made by impregnating a fibrous felt with a photocurable resin, wrapping the felt in bandage form around the injured member until a sufficient thickness is built up, then curing the resin by exposing the wrapped ''''cast'''' to actinic radiation for a time sufficient to convert the impregnated wrapping into a rigid substance.
