<p>A stabilisation and gripping device for use with a compression test machine to measure strain vs load characteristics of, in partricular composite material uni-directional ply, specimens includes a guide sleeve (1), two hollow open ended end-blocks (2) adapted to slidably fit within the guide sleeve and to co-operate with parts of the machine for applying compressive forces to the specimen, and two pairs of collets (6) each pair for gripping a separate one of two ends of the specimen (9), said collets having a planar gripping inner surface (7), at least one outer surface tapered with respect to said gripping surface and corresponding to a tapered inner surface of said end blocks, and a planar outer surface for co-operation with a substantially planar inner surface of said end blocks so that said collets may be non-rotatably inserted in said end blocks in a position in which the respective inner surfaces are parallel and pairs of said inner surfaces define a location for the specimen ends.</p> |
