Journal ArticleDOI
Steel-composite hybrid headstock for high-precision grinding machines
TL;DR: In this paper, the headstock of a precision grinding machine was reinforced using glass fiber epoxy composite material, and the static and dynamic characteristics were investigated analytically and experimentally in order to improve the grinding machine performance.
Journal ArticleDOI
Smart cure cycle with cooling and reheating for co-cure bonded steel/carbon epoxy composite hybrid structures for reducing thermal residual stress
TL;DR: In this paper, a smart cure cycle with cooling and reheating for co-cure bonded steel/carbon epoxy composite hybrid structures was developed to reduce the fabricational thermal residual stress between the steel and carbon epoxy composites material.
Journal ArticleDOI
Binary mixture rule for predicting the dielectric properties of unidirectional E-glass/epoxy composite
Woo Seok Chin,Dai Gil Lee +1 more
TL;DR: In this article, the dielectric properties of unidirectional E-glass fiber reinforced epoxy composites were tested with the free space method, from which theoretical models and mixture equations for estimating its Dielectric constant were proposed with respect to the fiber volume fractions.
Journal ArticleDOI
Damping improvement of machine tool columns with polymer matrix fiber composite material
TL;DR: In this article, a hybrid column was manufactured by adhesively bonding glass fiber reinforced epoxy composite plates to a cast iron column, which was calculated with respect to the fiber orientation and thickness of the composite laminate plate and compared to the measured damping capacity.
Journal ArticleDOI
Manufacturing of Co-Cured Composite Aluminum Shafts with Compression during Co-Curing Operation to Reduce Residual Thermal Stresses
Durk Hyun Cho,Dai Gil Lee +1 more
TL;DR: In this article, a hybrid shaft was manufactured by co-curing carbon fiber epoxy composite to an aluminum shaft to increase the bending natural frequency and damping without reducing the torque transmission capability of the shaft.
