Abstract (en)
[origin: WO9830769A1] A shaped article, at least one domain of which has a three-dimensionally reinforced composite structure comprising a matrix and a reinforcing system (2, 4, 5, 6), the reinforcing system comprising bodies such as bars, wires, cables or plates embedded in the matrix and extending three-dimensionally in first (4, 5), second (2) and third (6) dimensions therein, the reinforcing system being tension interlocked in at least one dimension in that reinforcement components extending in the first and/or second dimension are tension interlocked to reinforcement components extending in the same dimension(s), but at a transverse distance therefrom, by transverse reinforcement components extending in a dimension transverse to a plane or surface defined by the reinforcement in the first and/or second dimension. The matrix is preferably a dense cement-based matrix prepared from cement, microsilica, a concrete superplasticiser and water, or a metallic matrix. The shaped articles are capable of absorbing high energy with retention of a substantial degree of internal coherence, e.g. under exposure to high velocity impact.
