The aim of this paper is to determine the heat transfer properties biaxial carbon fabrics different architectures, including non-crimp stitch bonded fabrics, plain, twill and satin woven fabrics. specific capacity was determined via DSC (differential scanning calorimetry). A novel method numerical analysis temperature maps from a video using high-resolution thermal camera investigated for measu...

The use of metallic materials in automotive industry leads to increasing fuel consumption and cost, so trends are starting lighter cheaper materials. In applications, fibers used composites because they stronger, stiffer, than bulk materials, can achieve higher energy absorbing compared purpose this work is study the potential utilization natural crash applications. experimental procedures (the...

In recent years, the use of synthetic fiber-reinforced polymer (FRP) composites has gained significant popularity in structural engineering. The confinement concrete to improve its axial behavior been one most encountered applications such FRP materials. However, these materials are far from being friendly environment due their carbon release during production. Besides, high cost is still a maj...

The influence of high-temperature argon heat-treatment on the microstructure and room- temperature in-plane tensile properties 2D woven CVI unidirectional MI SiC/SiC composites with Hi-Nicalon™-S SiC fibers was investigated. were heat-treated between 1200 1600 °C for 1- 100-hr, 1315 1400 up to 2000 hr. In addition, fast fracture strengths these also measured in air. Both exhibited different deg...

BACKGROUND There are different materials and principles used in the construction of bed encasings. Although these covers claim to have antimite properties, they might not be mite proof. OBJECTIVE This study evaluated the effectiveness of mite penetration of these covers by using the Siriraj chamber method. METHODS Thirty-two covers collected from 9 different countries were categorized accor...

INTRODUCTION Mouse models are used frequently to study effects of bone diseases and genetic determinates of bone strength. Murine bones have an intracortical band of woven bone that is not present in human bones. This band is not obvious under brightfield imaging and not typically analyzed. Due to the band's morphology and location it has been theorized to be remnant bone from early in life. Fu...

Electrode materials are key components for fiber solar cells, and when combined with active layers (for light absorption and charge generation) in appropriate ways, they enable design and fabrication of efficient and innovative device structures. Here, we apply carbon nanotube yarns as counter electrodes in combination with CdSe nanowire-grafted primary electrodes (Ti wire) for making fiber and...

Nano materials possess unique mechanical, physical, and chemical properties. They are small, and have an ultrahigh surface area, making them suitable for air filter applications since air filtration is necessary to protect sensitive components from harmful particulates and gaseous contaminants. The electrospinning method has been recognized as an efficient technique for fabricating polymer nano...

A hydrodynamic permeability of membranes built up by porous cylindrical or spherical particles with impermeable core is investigated. Different versions of a cell method are used to calculate the hydrodynamic permeability of the membranes. Four known boundary conditions, namely, Happel's, Kuwabara's, Kvashnin's and Cunningham/Mehta-Morse's, are considered on the outer surface of the cell. Compa...

Objective. To assess fracture resistance and failure mode of repaired fiber-reinforced composite (FRC) cusp-replacing restorations. Methods. Sixteen extracted human premolars with fractured cusp-replacing woven (Group (A)) or unidirectional (Group (B)) FRC restorations from a previous loading experiment were repaired with resin composite and loaded to fracture. Results. Differences in fracture ...
