Dielectric Characteristics of E-glass-Polyester Composite Containing Conductive Carbon Black Powder
Woo Seok Chin,Dai Gil Lee +1 more
TL;DR: In this article, the dielectric properties of an E-glass-polyester composite containing conductive carbon black are measured with the free space method in the X-band frequency range.
Journal ArticleDOI
Adhesion strength of glass/epoxy composite embedded with heat-treated carbon black on the surface
Sang-Wook Park,Dai Gil Lee +1 more
TL;DR: In this article, the surface of a glass/epoxy composite material was embedded with oxidized carbon black by heat treatment to enhance the adhesion strength of the composite structure, and the surface free energies and lap shear strengths were investigated in terms of the heat treatment conditions and the amount of embedding.
Journal ArticleDOI
Composite hybrid valve lifter for automotive engines
Seungwoo Lee,Dai Gil Lee +1 more
TL;DR: In this paper, a hybrid valve lifter composed of composite and steel for use in a valve train in an automotive internal combustion engine is described, where the focus is placed on reducing the mass of the lifter in order to achieve higher fuel efficiency.
Journal ArticleDOI
Performance improvement by glass fiber of adhesively bonded metal joints at the cryogenic temperature
TL;DR: In this paper, the performance of adhesively bonded joints composed of aluminum sheet and stainless steel foils was investigated at the cryogenic temperature for the secondary barrier LNG (Liquefied Natural Gas) containment system.
Journal ArticleDOI
Design of the hybrid composite face with electromagnetic wave transmission characteristics of low-observable radomes
TL;DR: In this paper, a hybrid composite face composed of both E-glass/epoxy and aramid-epoxy composites for low-observable radomes was designed to exploit the better characteristics of both composites.
