The problem can be more complex when the plies are thin. In this paper, quasi-static indentation tests were conducted on thin-ply laminates to understand qualitatively the damage mechanisms and their sequence during low-velocity impact loading. TeXtreme® plain weave plies were used with two different thicknesses, 0.08 mm and 0.16 mm (referenced as ultra-thin-ply and thin-ply, respectively), and tested under different load levels. Load-displacement curves were analyzed and the extent of damage was inspected using optical microscopy and ultrasonic technique. The results showed that the damage onset occurs earlier in thin-ply laminates. The damage onset in thin-ply laminates is matrix cracking which induces delaminations, whereas for ultra-thin-ply laminates is due to delaminations which are induced by shear forces and small amount of matrix cracking. Moreover, the fiber breakage appears earlier in ultra-thin-ply laminates" , "dc.description.sponsorship": "This work has been partially funded by the Spanish Government (Ministerio de Economia y Competitividad) and the European Union under contracts DPI2012-34465, MAT2013-46749-R and MAT2015-69491-C3-1-R, and by the financial support of ERANet AirTN 01/2012 under the project entitled ‘‘Damage tolerance for thin ply textile composites (DAMTEX)”" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "Elsevier" , "dc.relation": "info:eu-repo/grantAgreement/MINECO//DPI2012-34465/ES/EVALUACION DE COMPOSITES LAMINADOS DE CAPAS FINAS PARA APLICACIONES AERONAUTICAS Y AEROESPACIALES/" , "dc.relation": "info:eu-repo/grantAgreement/MINECO//MAT2013-46749-R/ES/DIAGRAMAS DE FACTORES DE CONCENTRACION DE TENSIONES PARA MATERIALES CASI-FRAGILES/" , "dc.relation": "info:eu-repo/grantAgreement/MINECO//MAT2015-69491-C3-1-R/ES/HIBRIDACION LOCAL DE MATERIALES COMPUESTOS LAMINADOS PARA MEJORAR SU TOLERANCIA AL DAÑO/" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://dx.doi.org/10.1016/j.compositesa.2016.04.010" , "dc.relation.ispartof": "© Composites.
