A Study of Cutting Temperatures in Turning Glass-Fiber-Reinforced -Plastic (GFRP) Composites with nose radius worn tools

Chang C-S, National Ilan University, TW

Abstract: Nine kinds of chamfered main cutting edge carbide tools were used in turning of glass-fiber-reinforced plastics (GFRP) materials to study the temperature of tip's surface and the cutting forces. Force data from these tests [...]

Interfacial nanostructure dictates macro-structural properties of carbon-carbon composites

Singh M., Vander Wal R., Pennsylvania State University, US

Carbon-carbon composites, originally developed for aerospace applications, are materials that consist of a carbonaceous matrix with an embedded carbon filler providing the required reinforcement for thermal and mechanical stability. An important aspect of composites is [...]

Recoverable Lightweight Nanocomposites

Huckleby A.B., Li J., Shahrizan Jamal M., Zhang M., Florida State University, US

The demand for lightweight and strong structures continues to rise especially for weight critical applications such as aerospace and automotive. It is also desired that the materials can recover after being deformed. In this work, [...]

Self-Activated Morphing Carbon Fiber Composites Via Cyclic Internal Stresses

Casalotti A., Lanzara G., University of Roma Tre, IT

An innovative concept to exploit self-activated morphing composite materials is presented and demonstrated experimentally. In this design, shape changes of a carbon fiber composite are achieved by combining two key ingredients: fibers orientation and temperature-sensitive [...]

The Improvement of Carbon Fibre Composites Using Nanofibre Interleaving Veils

Beckermann G.W., Hosie I., Revolution Fibres, NZ

Revolution Fibres have developed Xantu.Layr®, the world’s first commercially available nanofibre interleaving veil for use in carbon fibre reinforced composite materials. Produced using a proprietary production method (Sonic Electrospinning Technology), Xantu.Layr® is a non-woven web [...]

Advanced Film Thermal Protectors for Electronic Devices

Wang Y., UCI, US

This advanced thermal protector is based on the patent (U.C. Case No. 2012-130), which provides one-way heat flow function, i.e. enabling heat dissipation from the electronic devices, while preventing outside heat from thermally damaging the [...]

Development of Novel Nanocomposite Dielectrics for High Voltage, High Energy Density Multilayer Ceramic Capacitors (MLCCs) Applications.

Tan C., Aegis Technology, Inc, US

There are demanding requirements on multilayer ceramic capacitor (MLCC)-based power capacitors in the development of more advanced electronics and platforms for both civic and military applications. Currently used MLCCs, however, suffer from limitations of low [...]

Discovery of the dichroic effect in cuprous oxide particles for the development of novel composite materials that change colour with direction of light source

Wrigglesworth E.G., Johnston J.H., Victoria University of Wellington, NZ

When a material displays one colour in transmitted light, but a different colour in reflected light, it is known as the dichroic effect. The oldest and most famous example of this effect is the Lycurgus [...]

Reinforced Ceramic Composites Fabricated From High-Char Yield Polymers

Butler T., Dyatkin B., Deese S.M., Laskoski M., U.S. Naval Research Lab, US

Advancements in high-speed propulsion systems have spurred demand for materials which can withstand the harsh conditions necessitated by this hypersonic travel. Ultra-high temperature ceramics (UHTCs) such as transition metal borides, nitrides, and carbides melt at [...]

Properties and characterisation of an aluminum – silicon nitride fiber powder metal composite

Dougherty T., Xu Y., Nuenz Limited, NZ

There is an increasing demand for new light-weighting materials to improve fuel-efficiency in the automobile and aerospace industries. This has led to an increase in the use of aluminum over traditional metals, such as steel, [...]
