JIS K7165-2008《塑料–拉伸性能的测定–第5部分:单向纤维的试验条件》

1.1 This Standard specifies the test conditions for the determination of the tensile
properties of unidirectional fibre-reinforced plastic composites, based upon the general
principles given in JIS K 7161.
1.2 The test method is for obtaining tensile strength, modulus of elasticity in tension
and tensile stress-strain characteristics under the fixed condition from the tensile
behaviour using test specimens.
1.3 The test method is suitable for all polymer matrix systems reinforced with uni-
directional fibres.
The method is suitable for composites with either thermoplastic or thermosetting
matrices, including preimpregnated materials (prepregs). The reinforcements covered
include carbon fibres, glass fibres, aramid fibres and other similar fibres. The rein-
forcement geometries of unidirectional fibres covered include rovings and unidirectional
fabrics and tapes.
The method is not normally suitable for multidirectional materials composed of sev-
eral unidirectional layers at
