Tensile Tests on Unidirectional Laminates
Unidirectional laminates are normally tested longitudinally for fiber strength and transversely for bond strength. The specimens are reinforced at the ends with cap strips to avoid jaw breaks. This test, which is described in ISO, ASTM, EN, AITM, BSS, DIN, SACMA and CRAG standards, places high demands on the quality of the extension measurement and on the alignment accuracy.
