“…An explicit micromechanical finite element approach has been used by many researchers (Schuler et al 2000, Akisanya et al 2001, Peng et al 2005 to study the deformation behaviour of the MCF. This approach, although not capable of providing simulation of practical processes, can provide insight, at the material level, into composite consolidation.…”

“…However, simulations rely on the existence of suitable constitutive equations capable of determining the evolution of deformation and porosity in the composite when subjected to any general stress state. The few existing models for MCF composite consolidation (Wadley et al 1997, 1998, Schuler et al 2000, Akisanya et al 2001 have led to significant progress but can require many parametric finite element simulations to be carried out in order to determine the appropriate parameters appearing in the constitutive equations. Other approaches are unable to provide directly the constitutive equations, since they are micromechanical models which explicitly represent matrix, fibre and void which have to be meshed explicitly within the finite element model.…”

Physically based constitutive equations for the consolidation of matrix coated fibres (MCFs) arranged in hexagonal arrays are presented in this paper. The constitutive equations have firstly been developed using a variational method for a unit cell representing hexagonal array packing of the coated fibres under symmetric in-plane compressive load. The resulting constitutive equations have subsequently been generalized to multiaxial stress states and implemented into finite element software within a finite deformation framework to enable simulations of practical manufacturing processes. The model has been validated by comparing predicted results with those obtained from independently developed explicit micromechanical finite element models. The ability of the model to predict the observed behaviour has been tested by comparing the results of simulations with those of experiments. The model predictions compare well with the measured results. In addition the results of simulations suggest that the densification curves for square and hexagonal array packing effectively provide the lower and upper bounds, respectively, for practical consolidation behaviour of MCFs under uniaxial constrained compression.

“…Long bre reinforced metal matrix composites are taking on a primary role in the eld of advanced materials for aerospace structural applications owing to their speci c properties guaranteed by the coupling of a ceramic reinforcement with a metallic matrix [1][2][3][4][5]. To date, the majority of these composites have been fabricated by diffusion bonding techniques using the foil-bre-foil method [6,7] or from alternating layers of woven bre mats and matrix foils [8].…”

The present work is focused on the fabrication of long bre reinforced titanium composites by hot pressing of plasma-sprayed preforms. Thermal spraying of two different metallic matrices [Ti-6Al-2Sn-4Zr-2Mo-0.08Si (Ti6242S) and Ti-4.5Al-3V-2Mo-2Fe (SP700)] onto prearranged silicon carbide long bres was performed using controlled-atmosphere plasma spraying equipment (CAPS), allowing deposition processes also in the high-pressure range. After optimization of the plasma spraying procedure, composite multilayers were fabricated by hot pressing at 1200 bar with different combinations of process parameters (temperature in the range 850-940¯C, and application time from 30 to 45 min). Consolidated samples were characterized by microstructural investigation and tensile testing at room and high temperature (up to 600¯C). Push-out and push-back tests were performed to investigate interfacial properties.
