      Accés obert
      Glass fibre is the most widely used material for reinforcing thermoplastic matrices presently and its use continues to grow. A significant disadvantage of glass fibre, however, is its impact on the environment, in particular, ...

    • Template fabrication of 3D metallic microstructures by electrochemical etching and electroplanting 

      Hernández Díaz, David; Lange, Diego; Todorov Trifonov, Trifon; Garin Escriva, Moises; García Molina, Francisco Miguel; Rodríguez Martínez, Ángel; Alcubilla González, Ramón (2010)
      Text en actes de congrés
      Accés obert
      In this work, we show that macroporous silicon consisting of periodic arrays of etched pores is a feasible alternative for synthesis of 2D and 3d metallic microstructures due to its flexibility in the definition of complex ...

    • The tower press for obtaining olive oil: analysis through computer-aided engineering 

      Rojas Sola, José Ignacio; De la Morena De la Fuente, Eduardo; Hermoso Orzáez, Manuel Jesús; Hernández Díaz, David (Multidisciplinary Digital Publishing Institute (MDPI), 2020-11-19)
      Article
      Accés obert
      This article analyzes a large tower press used to press crushed olives to obtain olive oil. To this end, a study of computer-aided engineering (CAE) was carried out using the parametric software Autodesk Inventor Professional, ...

    • Topography of the interfacial shear strength and the mean intrinsic tensile strength of hemp fibers as a reinforcement of polypropylene 

      Hernández Díaz, David; Villar Ribera, Ricardo Alberto; Julian, Fernando; Tarrés Farré, Joaquim Agustí; Espinach, Francesc Xavier; Delgado Aguilar, Marc (Multidisciplinary Digital Publishing Institute (MDPI), 2020-02-20)
      Article
      Accés obert
      The strength of the interphase between the reinforcements and the matrix has a major role in the mechanical properties of natural ¿ber reinforced polyole¿n composites. The creation of strong interphases is hindered by the ...

    • Tuning the emissivity of 3D macroporous silicon in the mid-infrared 

      Hernández Díaz, David; Vega Bru, Didac; Garin Escriva, Moises; Todorov Trifonov, Trifon; Rodríguez Martínez, Ángel; Alcubilla González, Ramón (2010)
      Text en actes de congrés
      Accés obert
      Tailoring the thermal emission of a particular material by using periodic micro-structures has attracted great interest for its potential applications in heating and lighting systems or thermophotovoltaics. […] Metallic ...
