Influence Of Composite Materials Surface Metal Mesh On Helicopter Lightning Stroke Effects, Junling Huang, Jiayu Xie
Influence Of Composite Materials Surface Metal Mesh On Helicopter Lightning Stroke Effects, Junling Huang, Jiayu Xie
Journal of System Simulation
Abstract: The metal wire mesh is usually adopted to prevent the lightning stroke on composite materials. The effects of different materials and different thickness of metal mesh on helicopter lightning electromagnetic effect are compared. According to the method recommended by SAE-ARP5416, a numerical simulation software is used for carrying out the high current injection simulation. The results show that the surface mount metal mesh can effectively reduce the harm of lightning electromagnetic coupling effect; the difference between aluminum and copper on anti-lightning stroke effect is not obvious; when the thickness of aluminum grid is less than 0.15 mm, the …

Silicides And Composites Materials As Anodes For Lithium Ion Batteries, Jun-Mei Yan
Journal of Electrochemistry
The anode materials of Mg_(2)Si and MnSi were synthesized by mechanically activated annealing(MAA) techniques in this work and the in electrochemical performances were also studied.A series of composite materials of Mg_(2)Si and CNTs or CMS were prepared by ball-milling method respectively.The reversible capacities of the composites were higher than that of the pure Mg_(2)Si and pure carbon materials.The cyclic performances have been improved greatly by ball-milling of the Mg_(2)Si and carbon materials.Results show that ball-milling method is one kind of method to make alloy materials into practical use.
