Mechanical properties of GFRP composite materials at cryogenic temperatures.

Optical Properties of Composite Materials at High Temperatures

The optical properties of composite materials are studied theoretically as a function of temperature via a phenomenological model for temperatures up to the melting points of the materials. Both the Maxwell-Garnett and Bruggeman models are considered and the temperature variation of the optical constants of the metallic particles is obtained with an account of the dependence of both the electro...

Mechanical quality factor of a sapphire fiber at cryogenic temperatures

A mechanical quality factor of 1.1× 107 was obtained for the 199Hz bending vibrational mode in a monocrystalline sapphire fiber at 6K. Consequently, we confirm that pendulum thermal noise of cryogenic mirrors used for gravitational wave detectors can be reduced by the sapphire fiber suspension.

Mechanical Properties of Polymer Composite Materials

In this paper, composite materials and its properties are discussed in detail. It is also discussed their importance and replacement for metals because of their properties like low weight, corrosion resistance etc. Now-a-days, there is a great importance of usage of these materials in various applications in all Engg. Fields. The paper also brings out the manufacturing techniques and costs invo...

[1011] Scanning Thermal Microscopy on 2D Materials at cryogenic temperatures

Thermal transport in Graphene is of great interest due to its high thermal conductivity, for both fundamental research and future applications such as heat dissipation in electronic devices. Although, the thermal conductivity of graphene can reduce depending on the coupling to the substrate [1]. In this work, we report high-resolution imaging of nanoscale thermal transport in single and few lay...
