Efecto de la separación fibra-matriz sobre las propiedades mecánicas de una viga forjada en poliamida reforzada con fibra de vidrio
Baskaran, Maider; Morales, Unai; Esnaola, Aritz; Aretxabaleta, Laurentzi; Aurrekoetxea, Jon; Olaziregi Cuevas, Udane (Scipedia, 2022)In the present work, ribbed beams have been manufactured by forging fiberglassreinforced polyamide using two different temperatures. The higher processing temperature studied (300 ºC) ensures the filling of the mold in the ... -
The effect of cross-section geometry on crushing behaviour of 3D printed continuous carbon fibre reinforced polyamide profiles
Morales, Unai; Esnaola, Aritz; Iragi, Mikel; Aretxabaleta, Laurentzi; Aurrekoetxea, Jon (Elsevier, 2021)The present study has analysed the effect of cross-section geometry and the printing pattern of continuous carbon reinforced polyamide on the axial and radial crushing behaviour. Each geometry and printing pattern generated ... -
Effect of voids on the impact properties of Non-Crimp fabric carbon/epoxy laminates manufactured by liquid composite Moulding
Mendikute, Julen; Baskaran, Maider; Aretxabaleta, Laurentzi; Aurrekoetxea, Jon (Elsevier, 2022)A great effort has been made to quantify the detrimental effect of voids on CFRP, nevertheless, the effect on impact properties has been barely studied and when it has been considered, it has always been for prepeg materials ... -
Estudio teórico-experimental del comportamiento a impacto de baja velocidad de piezas estructurales fabricadas con termoplásticos
Aretxabaleta, Laurentzi (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2008)The substitution of metals by thermoplastic materials is increasing in structural applications in which lightness is essential. In many of these applications impact behaviour is a key factor, because impact produces the ... -
Impregnation quality diagnosis in Resin Transfer Moulding by machine learning
Mendikute, Julen; Plazaola Madinabeitia, Joanes; Baskaran, Maider; Zugasti, Ekhi; Aretxabaleta, Laurentzi; Aurrekoetxea, Jon (Elsevier Ltd., 2021)In recent years, several optimization strategies have been developed which reduce the overall defectiveness of the RTM manufactured part. RTM filling simulations showed that, even using optimized injection strategies, local ... -
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 ... -
Phase transformation fronts propagation during the Stress Induced Martensitic transformation in NiTi Shape Memory Alloy wires at impact strain rates
Aretxabaleta, Laurentzi; Aurrekoetxea, Jon; Zurbitu, Javier; Castillo López, Germán (EDP Sciences, 2009)Propagation of phase transformation fronts during the stress induced martensitic (SIM) transformation at impact strain rates, on the order of 10 s-1, was observed in situ by measuring changes in infrared radiation on the ... -
