“…Most of the experimental characterization of the mechanical behavior of continuous unidirectional alumina fiber reinforced aluminum that has been reported in the literature has focused on studies of the strength and deformation mechanisms of the composite loaded along the fiber axis. Compressive [23][24], tensile [25][26][27][28], bending [25], and fatigue [29] properties have been reported for loading applied along the fiber axis of unidirectional alumina fiber reinforced aluminum. Hall et al [30] studied the quasi-static and high strain rate properties of cross-ply unidirectional alumina reinforced aluminum MMC and found that the properties were strongly dependent on fiber distribution and alignment.…”

Continuous unidirectional ceramic fiber and woven fabric reinforced metal matrix composites (MMCs) have potential to obtain very high specific strengths and stiffnesses, but use in structural applications has thus far been limited by their inherently low ductility, particularly in tensile loading conditions. In this work, a multi-scale micromechanics based finite element framework is used to predict, and understand the effect of microstructure on the tensile deformation behavior, including progressive damage and failure, of ceramic fiber and fabric reinforced MMCs. A hierarchal approach is implemented in which a micro-scale model is used to determine the transversely isotropic elasto-plastic mechanical behavior of unidirectional fiber reinforced MMC based on the properties of an aluminum alloy matrix, individual ceramic fibers, and the fiber-matrix interface. The validated transversely isotropic constitutive behavior is then input into a unit cell model for a woven fabric MMC consisting of unidirectional MMC tows in

The probability of composite failure is a function of filament length when loaded under specific stress [32]. As demonstrated by the illustration in Fig.…”

A novel method was developed, based on thixotropic nature of semi-solid slurry of aluminum silicon alloy, for the effective dispersion and distribution of short carbon fibers (C sf ) under intensive shear stress (τ) into the eutectic without physical or chemical damage.The C sf were distributed homogeneously into the matrix at optimum conditions: a temperature of 576-580 °C, around 48% of solid fraction, and rotation speed of mixing was at 100 rpm. The gas entrapment and porosity was a challenge in the fabrication the aluminum composite by thixomixing, and its size increased when the samples were heat treated. The extruded and heat treated composites had around 24% improvement of mechanical strength as assessed by tensile tests. The predominant deposition of silicon and its intermetallics at the interfacial region improved the wettability and adherence to achieve good mechanical properties. The formation of some intermetallics can be helpful to overcome low wettability effects and their structural evolutions were impressive. The fractography analysis illustrated the ductile fracture with some plastic deformation as the results of dimples and some fiber pull-out in the fractured surface. Ultra-micro hardness evaluation showed good interfacial bonding after heat treatment. The thixomixing process can be developed to produce various composites with different reinforcement.

“…The fiber orientation for a given fiber was determined as follows: (i) Images taken in optical microscopy (VHX-500F CCD camera, which has a resolution of 1600 Â 1200 pixels in size) were preprocessed by the aid of the ImageJ software. (ii) Functions in ImageJ software "Make Binary" and "Watershed" used to get binary photos, then function of "Noise / Remove outlier" [21] employed to get clear boundary carbon fiber images of CF/PA6 and CF/Epoxy laminates as shown in Fig. 5(a) and (b), respectively.…”

“…In a UD composites loaded along its fibers, unless the matrix is brittle, internal damage is in the form of individual broken fibers [21]. The tendency of one broken carbon fiber to cause neighboring carbon fibers break determines the fracture behavior and mechanical properties like tensile strength.…”
