THE STRUCTURE DESIGN OF MULTIAXIAL WARP KNITTED FABRIC IN WIND POWER GENERATION
Multiaxial warp knitted technology is the way that can lay-in more weft at the same time,the multiaxial warp knitted fabric produced by this technology has stable size,small elongation and other characteristics,has been appreciated in the industrial field extensively.This paper introduces the structure and performance of multiaxial warp knitted fabric and the method to show the direction of the lay-in yarn,introduces the application of multiaxial warp knitted fabric in wind power generation in detail including the structure of the blade,the materials,the stress analysis of the blade and the manufacturing process.As a example of biaxial warp knitted fabric,design and analysis it based on WKCAD.
Organic bulk heterojunction solar cells suffer from a huge, nonmonotonic loss of open-circuit voltage ${V}_{o\phantom{\rule{0}{0ex}}c}$ at low temperatures, which thwarts their practical application. The authors incorporate energetic disorder into a drift-diffusion model to study the ${V}_{o\phantom{\rule{0}{0ex}}c}-T$ relations under various working conditions. In reproducing the empirical observations, they find that disorder-suppressed carrier mobility is the culprit. This work provides a comprehensive picture from the charge-dynamics perspective that will facilitate the engineering of this emerging class of devices.
