  • On the delamination self-sensing function of Z-pinned composite laminates 
    Zhang, B.; Allegri, Giuliano; Yasaee, Mehdi; Hallett, Stephen R.; Partridge, Ivana K. (Elsevier, 2016-03-19)
    This paper investigates for the first time the usage of through-thickness reinforcement for delamination detection in self-sensing composite laminates. Electrically conductive T300/BMI Z-pins are considered in this study. ...
  • On-line monitoring of multi-component strain development in a tufting needle using optical fibre Bragg grating sensors 
    Chehura, Edmon; Dell'Anno, Giuseppe; Huet, Tristan; Staines, Stephen E.; James, Stephen W.; Partridge, Ivana K.; Tatam, Ralph P. (Institute of Physics, 2014-05-20)
    Dynamic loadings induced on a tufting needle during the tufting of dry carbon fibre preform via a commercial robot-controlled tufting head were investigated in situ and in real-time using optical fibre Bragg grating (FBG) ...
  • Parameter estimation in equivalent circuit analysis of dielectric cure monitoring signals using genetic algorithms. 
    Kazilas, Michalis C.; Skordos, Alexandros A.; Partridge, Ivana K. (Taylor & Francis, 2005-04-01)
    This communication concerns the treatment of dielectric data obtained from experiments following the chemical hardening process (cure) in thermosetting resins. The aim is to follow, in real time, the evolution of the ...
  • Percolation threshold of carbon nanotubes filled unsaturated polyesters 
    Battisti, Andrea; Skordos, Alexandros A.; Partridge, Ivana K. (Elsevier Science B.V., Amsterdam., 2010-04-01)
    This paper reports on the development of electrically conductive nanocomposites containing multi-walled carbon nanotubes in an unsaturated polyester matrix. The resistivity of the liquid suspension during processing is ...
  • Performance of tufted carbin fibre/epoxy composites 
    Treiber, Johannes W. G. (Cranfield University, 2011-03)
    The thesis presents a detailed analysis of the effects of one-sided access z-direction reinforcement, ‘tufting’, on the morphology and mechanical performance of the resulting MVR-444 epoxy matrix/carbon fibre fabric ...
  • RTM processing and electrical performance of carbon nanotube modified epoxy/ fibre composites 
    Reia da Costa, Elisabete F.; Skordos, Alexandros A.; Partridge, Ivana K.; Rezai, Amir (2012-04-30)
    This investigation focuses on nanoparticle filtration in the processing of multiscale carbon and glass fibre composites via resin transfer moulding. Surface modified and unmodified carbon nanotubes (CNTs) were incorporated ...
  • Rubber-toughened epoxy loaded with carbon nanotubes: structure-property relationships 
    Salinas-Ruiz , Maria del Mar; Skordos, Alexandros A.; Partridge, Ivana K. (Springer Science Business Media, 2010-05-01)
    The paper reports on the preparation, structure and properties of ternary thermosetting blends, based on DGEBA epoxy, cured with 3,3′-DDS and modified by the addition of CTBN reactive liquid rubber and/or 0.3wt% of ...
  • Suppressing delaminations in composites across a range of loading modes 
    M’membe, Beene; Yasaee, Mehdi; Hallett, Stephen R.; Partridge, Ivana K. (2017-08-31)
    This study presents two means of achieving high fracture toughness throughout the entire mixed Mode I/II test range, using customised placement of composite and metal Z-pins in hybrid arrays, and novel hybrid metal/composite ...
  • Thermomechanical analysis of a toughened thermosetting system. 
    Zarrelli, M.; Skordos, Alexandros A.; Partridge, Ivana K. (Springer Science Business Media, 2008-03-01)
    The experimental results of viscoelastic mechanical tests, at five different levels of conversion, are reported for a thermoset composite matrix system toughened with an appropriate percentage of a thermoplastic polymer. ...
  • Toward a constitutive model for cure dependent modulus of a high temperature epoxy during the cure 
    Zarrelli, M.; Skordos, Alexandros A.; Partridge, Ivana K. (Elsevier Science B.V., Amsterdam., 2010-12-31)
    A constitutive model, based on Kohlrausch-Williams-Watts (KWW) equations, was developed to simulate the evolution of the dynamic relaxation modulus during the cure of a "high temperature' epoxy. The basic assumption of ...
  • Tufting of complex composite structures 
    Lombetti, D. M. (Cranfield University, 2015-12)
    This study focuses on the effect of tufting on the mechanical and electrical properties of carbon composites using a variety of tuft materials, such as aramid, steel and copper. Several configurations were investigated ...
