Abstract

A crack is arrested by wrapping a band (10) of continuous non-metallic fibres in a resin matrix around the object (12) in a direction perpendicular and curing the resin matrix. The resin and fibres may be applied separately, and the fibres may be held in a unit. High tensile strength fibres are used, typically glass fibres in rovings suitably oriented in the band (10'). The arrestor may be formed in situ as above, or separately on a mandrel for example, and subsequently fitted to the object. The arrestor may be used to inhibit the formation of cracks, or to prevent the development of a crack already formed. A plurality of arrestors are normally fitted to the object, spaced along an object and/or at the ends of a formed crack. <IMAGE>
