Thanks to the low pulling forces inherent to this technology, we could manufacture a quasi-isotropic laminate with high fiber content (62% in volume). Even if just one fifth of the reinforcement was arranged longitudinally, the fiber orientation at the ±45° and 90° layers was not distorted. The in-plane properties of this new balanced reinforcement configuration improved the impact and notched resistance compared to a reference configuration typical of conventional pultrusion, consisting of roving and continuous strand mats. Additionally, the tensile strength achieved in the transversal direction for the new configuration was an order of magnitude higher. Therefore, this novel technology has the potential to broaden the applications targeted by pultrusion to those where multiaxial load cases could be encountered. eng © 2024 Wiley impact behavior Pultrusion Stress concentration factor Ultraviolet curing ODS 7 Energía asequible y no contaminante ODS 8 Trabajo decente y crecimiento económico ODS 9 Industria, innovación e infraestructura ODS 11 Ciudades y comunidades sostenibles ODS 12 Producción y consumo responsables ODS 13 Acción por el clima Impact and notched strength of multiaxially reinforced out of die UV cured pultruded profiles http://purl.org/coar/resource_type/c_6501
