Development of a lightweight, strong and energy-absorbing material that has potential application for the protection of vehicles and occupants against impact and blast, is a difficult challenge facing the materials community. Aluminium matrix syntactic foams will be investigated as a possible core material as part of a multi-layered protection system for military vehicles. Aluminium matrix syntactic foams are composite materials consisting of an aluminium matrix implanted with hollow or porous ceramic particles. This paper investigates the mechanical properties of aluminium matrix syntactic foam with different sizes of ceramic micro-spheres and different grades of aluminium, fabricated by the pressure infiltration method. The static crushing behaviour of the foam was investigated under two test conditions using an Instron 4505 machine. Results are compared and discussed. The dynamic compressive response was investigated using a drop-weight impact test machine. It was found that the particle size of the ceramic micro-spheres and the grade of the aluminium metal have a significant effect on the energy absorption capacity of the material. The compressive strength of the syntactic foam was found to increase with increasing compressive strength of the metal matrix.

The Matrix

The micromechanical properties of a Al alloy/SiC hollow sphere syntactic foams composite material have been studied using the Solidwork simulation code applied the finite element method (FEM). The simulated results have shown that the values of quasi-static compressive strength, plateau stress, and densification strain are 175 MPa, 120 MPa and 0.50, respectively. The general trend of dynamic stress–strain graphs is similar to quasi-static compression graphs. The compressive properties of the composite are not strain rate sensitive. The simulated peak strength value is ≈140 MPa. Al matrix and SiC hollow sphere exhibit different mechanical behaviour. The ultimate stress is found near the interface of composites. The failure initiates by the fracture of weak particles, some of the cracks can propagate to the matrix as well. Shear band formation in the matrix and shearing of SiChs lead to the major failure activity.
