Analysis of axial crushing behaviour of unsaturated polyester and vinyl ester composites manufactured by out of die ultraviolet cured pultrusion
Sáenz Domínguez, Iván; Tena Merino, Iosu; Esnaola, Aritz; Sarrionandia, Mariasun; Aurrekoetxea, Jon (2018)This paper analyses the axial crushing behaviour and flexural properties of novel unsaturated polyester (UP) and vinyl ester (VE) composites, manufactured by out of die ultraviolet (UV) cured pultrusion. The relation between ... -
An analytical model of through-thickness photopolymerisation of composites: Ultraviolet light transmission and curing kinetics
Tena Merino, Iosu; Sarrionandia, Mariasun; Aurrekoetxea, Jon (Elsevier, 2020)In this paper, a kinetic model able to predict the evolution of the through-thickness degree of cure of ultraviolet (UV) cured composites has been developed and validated. The kinetic model, which is based on the autocatalytic ... -
Design and characterisation of cellular composite structures for automotive crashboxes manufactured by out of die ultraviolet cured pultrusion
Sáenz Domínguez, Iván; Tena Merino, Iosu; Esnaola, Aritz; Sarrionandia, Mariasun; Aurrekoetxea, Jon (Elsevier B.V., 2019-03-01)The present paper analyses the feasibility of designing a honeycomb-like crash-box, as a cellular structure, based on data obtained from the characterisation of the building block. In order to generalise the conclusions ... -
Effect of alumina tri-hydrate filler on the mechanical and optical properties of flame-retardant ultraviolet cured vinyl ester composites
Tena Merino, Iosu; Sáenz Domínguez, Iván; Sarrionandia, Mariasun; Aurrekoetxea, Jon (2018)This research study is focused on the effect of alumina tri-hydrate (ATH) filler on the mechanical and optical properties of flame-retardant ultraviolet cured vinyl ester composites. In particular, vinyl ester formulations ... -
Impact and notched strength of multiaxially reinforced out of die UV cured pultruded profiles
Ruiz de Eguino, Imanol; Tena Merino, Iosu; Sáenz Domínguez, Iván; Sarrionandia, Mariasun; Aurrekoetxea, Jon (Wiley, 2024)The present paper highlights the benefits of multiaxially reinforced profiles manufactured by out of die ultraviolet (UV) cured pultrusion. Thanks to the low pulling forces inherent to this technology, we could manufacture ... -
Impact performance of out of die UV cured pultruded profiles for vessel structures
Ruiz de Eguino, Imanol; Tena Merino, Iosu; Arruti Lapeira, Ander; Sarrionandia, Mariasun; Aurrekoetxea, Jon (École Polytechnique Fédérale de Lausanne, 2022)Out of die ultraviolet (UV) cured pultrusion is an automated process for manufacturing bent profiles that can replace the labour-intensive processes currently employed for manufacturing stiffeners for vessels structures. ... -
Optimization of the CRTM process by means of monitoring techniques
Baskaran, Maider; Aretxabaleta, Laurentzi; Sarrionandia, Mariasun; Aurrekoetxea, Jon; Dueñas, A. (Scipedia, 2018)In this work the feasability of the monitoring system, composed of flow-rate and injection pressure sensors, in addition to the pressure sensors integrated in the mold, is demonstrated to determine the optimal process ... -
Paneles fabricados mediante curado UV de prepregs fuera de autoclave reforzados con perfiles de pultrusión UV
Ruiz de Eguino, Imanol; Arruti Lapeira, Ander; Sáenz Domínguez, Iván; Tena Merino, Iosu; Sarrionandia, Mariasun; Aurrekoetxea, Jon (Scipedia, 2023)Los materiales compuestos, gracias a sus elevadas propiedades específicas, buena resistencia a la corrosión y libertad de diseño, están en la agenda estratégica de muchos sectores de gran valor añadido como la aeronáutica, ...
