Applications of Polymer Matrix Syntactic Foams

A collection of applications of polymer matrix syntactic foams is presented in this article. Syntactic foams are lightweight porous composites that found their early applications in marine structures due to their naturally buoyant behavior and low moisture absorption. Their light weight has been beneficial in weight sensitive aerospace structures. Syntactic foams have pushed the performance bou...

Predicting Mechanical Properties of Metal Matrix Syntactic Foams Reinforced with Ceramic Spheres

A model is presented that predicts peak stress, minimum stress, average stress, densification strain, and composite density in order to determine the energy absorption per unit volume and energy absorption per unit mass of metal matrix syntactic foams reinforced with hollow ceramic spheres subjected to unconstrained compression testing. Comparison of predictions to experimental data for Al-A206...

The Effect of Matrix Composition on the Deformation and Failure Mechanisms in Metal Matrix Syntactic Foams during Compression

The influence of the matrix material on the deformation and failure mechanisms in metal matrix syntactic foams was investigated in this study. Samples with commercially pure Al (Al) and Al-12 wt % Si (AlSi12) eutectic aluminum matrix, reinforced by hollow ceramic spheres, were compressed at room temperature. Concurrently, the acoustic emission response and the strain field development on the su...

Controlled Shrinkage of Expanded Glass Particles in Metal Syntactic Foams

Metal matrix syntactic foams have been fabricated via counter-gravity infiltration of a packed bed of recycled expanded glass particles (EG) with A356 aluminum alloy. Particle shrinkage was studied and has been utilized to increase the particles' strength and tailor the mechanical properties of the expanded glass/metal syntactic foam (EG-MSF). The crushing strength of particles could be doubled...

Experimental and Finite Element Simulation of Nano-indentation on Metal Matrix Composites: Hardness Prediction

The scientific importance of nanocomposites are being increased due to their improvedproperties. This paper is divided into two parts. First, Al-Al2O3 nanocomposite wasproduced by using ball milling technique followed by cold compaction and sintering.Microstructure and morphology studies were done through SEM, TEM, and EDX anal-ysis on the produced powder. The mechanical properties of the produ...
