Oxyacetylene torch testing was performed at a range of angles attack on Cf/ZrB2-SiC-Y2O3 composites, from 10° to 90°. The ablation behaviour studied in-situ with thermography, and the post-ablation morphologies investigated optically elemental analysis. Significantly lower surface temperatures were observed oblique leading less damage in terms both oxidation extent material removal. Rudimentary...

Flexible paper-like semiconductor nanowire materials are expected to meet the criteria for some emerging applications, such as components of flexible solar cells, electrical batteries, supercapacitors, nanocomposites, bendable or wearable electronic or optoelectronic components, and so on. As a new generation of wide-bandgap semiconductors and reinforcements in composites, SiC nanowires have ad...

In-situ aluminum matrix composite is the innovation of high performance material technology and it has superior interfacial integrity and thermodynamic stability between the matrix and reinforcement. During synthesis, the ZrB2 particle is formed by exothermic reaction within the aluminum melt. As a result, small, fine and oxide free reinforcements are formed. Excessive temperature released from...

Fiber reinforced ceramic matrix composite is an attractive candidate as a structural material for future fusion power plants because of their light weight, high temperature capability, high strength and toughness. Ceramic matrix composite made of silicon carbide matrix and fibers (SiCf/SiC) is promising for nuclear and fusion technology due to its excellent radiation resistance, especially expo...

We demonstrate a route to synthesize ultra-high-temperature ceramic coatings of ZrB2 at temperatures below 1300 K using Zr/B reactive multilayers. Highly textured crystalline ZrB2 is formed at modest temperatures because of the absence of any oxide at the interface between Zr and B and the very short diffusion distance that is inherent to the multilayer geometry. The kinetics of the ZrB2 format...

In recent years the aluminum matrix composites are gaining wide spread applications in automotive, aerospace, defense, sport and other industries. The reason for this is their exciting properties like high specific strength, stiffness, hardness, wear resistance, dimensional stability and designer flexibility. The present work reports on mechanical properties and microstructure analysis of Al-Si...

This paper compares the values of the thermal and fire resistance properties of composites made using the hand layup technique. E-Glass fiber reinforced epoxy composites was fabricated by filling varying concentration of aluminum oxide (Al2O3), magnesium hydroxide(Mg(OH)2), silicon carbide (SiC), and hematite powder. The main aim of this work was to determine the thermal conductivity, thermal e...
