The Study of Electromagnetic Shielding Materials for Plastic Packaging in Laser Modules

Cheng, Jei-Yen 04 July 2000 (has links)
Electromagnetic shielding materials for plastic packaging in laser modules application were studied experimentally. Bipheny1, Nylon and LCP mixed with Al-powder, Al-flake, carbon-fibers and steel-fibers was fabricated and measured in shielding effectiveness(SE) for EMI. Compression molding, double-screw extrusion and injection molding were used for fabrication. We examed the mechanical properties and shielding effectiveness of these compounds. The SE of conductive plastics was measured to be 40dB at 30MHz and 60dB at 1GHz for carbon-fiber and plastic mixture. The experiment result indicates that introducting conductive carbon fiber fillers into plastics will produce conductive composites having an excellent SE to reduce EMI. With these excellent SEs, such conductive carbon fiber fillers into plastics are suitable for use in low-cost laser modules.

Analysis of glass reinforced side impact beams for hybrid electric vehicle.

Su, Dehai January 2008 (has links)
M. Tech. Mechanical Engineering / In order to increase the vehicle crashworthiness and decrease the weight of the vehicle in today’s automotive industries, composite materials have been replacing the conventional high strength steel material. The main advantage of composite material is the very high weight to strength ratio that will result in lighter automobiles, which will improve fuel efficiency and reduce exhaust emissions. In this research, the optimal orientation of fiber within the matrix was explored. It was found that different orientation of the fiber in the different matrix resulted in different mechanical properties and energy absorption rate.
