Flame and silane treatments for improving the adhesive bonding characteristics of aramid/epoxy composites
TL;DR: In this paper, a fast and cost-effective surface treatment with flame and silane coupling agent treatments has been developed for the surface treatment of aramid/epoxy composite faces to improve the adhesive bonding characteristics of lightweight sandwich stealth radome structures.
Journal ArticleDOI
Development of the anthropomorphic robot with carbon fiber epoxy composite materials
TL;DR: In this paper, the authors designed and manufactured a forearm of an anthropomorphic robot with high modulus carbon fiber epoxy composite to reduce the mass and moment of inertia of the arm.
Journal ArticleDOI
Machinability of carbon-fiber epoxy composite-materials in turning
TL;DR: In this paper, the machinability of high-strength carbon fiber-epoxy composite materials in turning has been investigated experimentally and the chip formation mechanisms and the Taylor tool-wear constants have been determined and the surface roughness has been measured with respect to cutting speeds and feeds.
Journal ArticleDOI
Effect of wear debris on the tribological characteristics of carbon fiber epoxy composites
TL;DR: In this paper, a model for the effect of wear debris on the friction and wear of carbon composites with micro-groove was proposed. And the wear characteristics of carbon/epoxy composite materials with microgrooves were investigated by dry sliding test with respect to applied pressure.
Journal ArticleDOI
Design of carbon fiber composite shafts for high speed air spindles
Kyung Geun Bang,Dai Gil Lee +1 more
TL;DR: In this paper, a high speed air spindle composed of a carbon fiber epoxy composite shaft and two steel flanges was designed for maximum critical speed considering both the deflection due to bending load and the radial expansion due to centrifugal force and temperature rise during high-speed rotation.
