As part of the U.S. Department of Energy’s Wind Partnerships for Advanced Component Technologies (WindPACT) program, Global Energy Concepts LLC (GEC) is performing a study concerning innovations in materials, processes and structural configurations for application to wind turbine blades in the multimegawatt range. The project team for this work includes experts in all areas of wind turbine blad...

A bi-functional nano-composite coating has been created on a porous Nomex® fabric support as a trap for aspirated virus contaminated water. Nomex® fabric was successively dip-coated in solutions containing cysteic acid functionalized alumina (alumoxane) nanoparticles and cysteic acid functionalized iron oxide (ferroxane) nanoparticles to form a nanoparticle coated Nomex® (NPN) fabric. From SEM ...

This paper aims to develop a new type of flexible cushioning composite material that can be applied protective appliances. Room temperature vulcanized silicone rubber (RTV rubber) was filled into five groups warp knitted spacer fabrics with different structural parameters, and composites filling rates 30%, 50% 70% were prepared. At the same time, there group without as control. Then infrared sp...

In order to meet the technical requirements, it is necessary infuse new functions into textile fabrics due rapid advancement in exploitation of textile-based materials various industrial applications [...]

Time-of-flight secondary ion mass spectrometry (TOF-SIMS) and X-ray photoelectron spectroscopy (XPS) are well established surface techniques that provide both elemental and organic information from several monolayers of a sample surface, while also allowing depth profiling or image mapping to be carried out. The static TOF-SIMS with improved performances has expanded the application of TOF-SIMS...

Belt conveyors, equipped with belts designed for transporting materials and finished products are used in many industries. They allow to transport delicate items, example made of glass, heavy products, such as canned food lightweight cardboard boxes. For this reason, the conveyor must, besides transferring power, ensure adequate conditions conveyed without compromising service life belt. Homoge...

The dielectric constants of nylon fabrics saturated with aqueous NaCl solutions, Fabric-Superdielectric Materials (F-SDM), were measured to be >10⁵ even at the shortest discharge times (>0.001 s) for which reliable data could be obtained using the constant current method, thus demonstrating the existence of a third class of SDM. Hence, the present results support the general theoretical SDM hyp...

A granular material is most likely to possess an initial anisotropic structure due to the depositional process or the previous stress history. There is also induced fabric anisotropy during shearing. Concerning the significant influence of fabric anisotropy on the stress-strain behaviour of a granular material, in-depth investigation on the two kinds of fabric anisotropy is essential. Initial f...

Numerical simulations of cyclic biaxial tests were performed on samples with polygonal particles having aspect ratios (AR) equal to 1 up to 3 to better understand the cyclic behaviour of granular materials. The samples are created by deposit under gravity leading to the existence of an inherent anisotropy. Nevertheless, for the sample with AR equal to 1, numerical tests were also performed from...
