Process for joining oblong bodies by means of memory-shape alloy connection elements

摘要

Individual parts, such as glass fibres (41, 42) are connected by means of memory-shape alloy connection elements (20); a, for example, sheet- or plate-shaped body (10, 20, 51) with at least one virtually cylindrical perforation (30), is used as the connection element, the perforation running approximately perpendicular to the surfaces of the body (10, 20); the smallest dimension of the surfaces of the body is greater by a multiple than the diameter of the perforations. The bodies (10) are deformed (20) at (T) Mf, into the major plane, under two-axis expansion, and at (T) Af they spring back approximately into the shape (51) before deformation. The individual parts (41, 42) are inserted in the perforations (30) at (T) Mf and are held in a force- fit in the connection (51) by the springing back of the bodies (20) into their original form (10, 51) at (T) Af.
