ABSTRACTWhen adhesively bonding Al/CFRP Single Lap Joint, a good bondperformance both on the strength and stiffness is important for CFRP bonded withaluminum structures. The objectives of the research were to: Investigate the effect ofstarting time to pressure and Al powder content to shear strength of Al/CFRP Singlelap joints with Al/epoxy...

ABSTRACTThe purpose of this work is to optimize the blade design of an axial-flow fan.Four different chord length and five twisting angle of their blades were studied. Thefan was designed by using NACA 5505 series. The first investigation is conducted tothe blade design in the variation of chord length. The base chord length is constant of130 mm...
