Journal ArticleDOI
Fracture toughness of the nano-particle reinforced epoxy composite
TL;DR: In this paper, nano-particle additives such as carbon black and nanoclay were mixed with epoxy resin to improve the fracture toughness of fiber-reinforced composites, and they measured the single edge notched bend specimen at the room (25°C) and cryogenic temperature (−150°C).
Journal ArticleDOI
Design and manufacture of an automotive hybrid aluminum/composite drive shaft
TL;DR: In this article, a one-piece automotive hybrid aluminum/composite drive shaft was developed with a new manufacturing method, in which a carbon fiber epoxy composite layer was co-cured on the inner surface of an aluminum tube rather than wrapping on the outer surface to prevent the composite layer from being damaged by external impact and absorption of moisture.
Journal ArticleDOI
Development of the composite RAS (radar absorbing structure) for the X-band frequency range
Woo Seok Chin,Dai Gil Lee +1 more
TL;DR: In this article, the conductive carbon black with the binder matrix of the E-glass/polyester composite has been used for fabricating the radar absorbing structure (RAS) of desired performance.
Journal ArticleDOI
Failure Modes of Foam Core Sandwich Beams under Static and Impact Loads
TL;DR: In this article, the authors describe the use of sandwich structures in load bearing structures due to their high specific stiffness and high specific strength, such as the ones used in this paper.
Journal ArticleDOI

In Uk Hwang,HaNa Yu,Seong Su Kim,Dai Gil Lee,Jung Do Suh,Sung Ho Lee,Byung Ki Ahn,Sae Hoon Kim,Tae Won Lim +8 more
TL;DR: In this article, a bipolar plate for automotive fuel cells was developed with carbon fiber composite by compression molding due to the fact that carbon/epoxy composite has not only high electrical and thermal conductivities, but also high specific stiffness and strength.
