1.1 This part of ISO527 specifies the test conditions for the determination of the tensile properties of isotropic and orthotropic fibre-reinforced plastic composites, based upon the general principles given in part1.
Unidirectionally reinforced materials are covered by part5.
1.2 See ISO527-1, subclause1.2.
1.3 The test method is suitable for use with the following materials:
-
fibre-reinforced thermosetting and thermoplastic composites incorporating non-unidirectional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combinations of such reinforcements, hybrids, rovings, short or milled fibres or preimpregnated materials (prepregs) (for directly injection-moulded specimens, see specimen 1A in ISO527-2:1993);
-
combinations of the above with unidirectional reinforcements and multidirectional reinforced materials constructed from unidirectional layers, provided such laminates are symmetrical (for materials with completely, or mainly, unidirectional reinforcements, see ISO527-5);
-
finished products made from these materials.
The reinforcement fibres covered include glass fibres, carbon fibres, aramid fibres and other similar fibres.
1.4 The method is performed using specimens machined from a test panel made in accordance with ISO1268 or by equivalent methods, or from finished and semi-finished products with suitable flat areas.
1.5 See ISO527-1, subclause1.5.
