Experimental study of the use of ultra-thin plies in quasi-isotropic laminates under cyclic tension after impact. En Materiales Compuestos (2024). Vol. 08 - COMUNICACIONES MATCOMP21 (2022) Y MATCOMP23 (2023), Núm. 3 - Caracterización - Daño, Fractura y Fatiga (1-4), Asociación Española de Materiales Compuestos (AEMAC).2531-0739https://hdl.handle.net/11441/155363In this work, the authors propose an experimental study on the possible improvement of the mechanical behaviour produced by ultra-thin plies in laminates subjected to cyclic loading after impact. More specifically, this work introduces the use of these plies in carbon fibre quasi-isotropic laminates, with the aim of studying the evolution of impact damage under tensile cyclic loads. To this aim, the behaviour of quasi-isotropic laminates consisting of conventional thickness plies is compared with laminates with 90° ultra-thin plies, keeping the same stacking sequence. When considering the same loading level, the damage evolution shows a lower progress and a later failure for the laminates containing ultra-thin plies.application/pdf4 p.spaAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/FatigaDañoImpactoCuasi-isótropoLáminas ultradelgadasFatigueDamageImpactUltra-thin pliesQuasi-isotropicinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess
