Development of Aluminum-based Hybrid Composites with Graphite Nanofibers/Alumina Short Fibers: Processing and Characterization
SAGE Publications - Tập 44 Số 16 - Trang 1929-1943 - 2010
J.S.S. Babu, K. Prabhakaran Nair, G. Unnikrishnan, Chung Gil Kang
In this study, aluminum-based hybrid composites were developed and characterized. Initially, a hybrid preform was fabricated using graphite nanofibers (GNFs) and alumina short fibers (Al2O3sf) with the total volume fraction of fiber at 10, 15, and 20%. The hybrid preforms were then infiltrated with aluminum alloy (A356), and the microstructure and...... hiện toàn bộ
Processing of surface-treated boron carbide-reinforced aluminum matrix composites by liquid–metal stir-casting technique
SAGE Publications - Tập 45 Số 23 - Trang 2371-2378 - 2011
V. P. Mahesh, Praseeda S. Nair, T.P.D. Rajan, B.C. Pai, R.C. Hubli
Boron carbide is one of the potential neutron-shielding materials and its use can be maximized for structural shielding application by dispersing it into metal matrixes such as aluminum. Dispersion of B4C and its interfacial stability is a major issue during its processing. This investigation is on the synthesis of B4C-reinforced 6061 aluminum mat...... hiện toàn bộ
Effect of sintering temperature on tribological behavior of Ce-TZP/Al2O3-aluminum nanocomposite
SAGE Publications - Tập 49 Số 28 - Trang 3507-3514 - 2015
Amin Bahrami, N. Soltani, M.I. Pech‐Canul
10Ce-TZP/Al2O3 nanoparticles as reinforcement can be a good substitute in aluminum matrix composites prepared through powder metallurgy. In this work, the effects of sintering temperature on the hardness, friction, and wear characteristics of Al-10Ce-TZP/Al2O3 composites have been investigated. Ce-TZP/Al... hiện toàn bộ
Raster angle mechanics in fused deposition modelling
SAGE Publications - Tập 49 Số 3 - Trang 363-383 - 2015
Bin Huang, Sarat Singamneni
Fused deposition modelling is one of the additive manufacturing processes in which a semi-solid polymer material is deposited line-by-line to construct 3D objects direct from computer aided design (CAD) models. Benefits inherent with additively manufacturing allowed effective competition with other traditional methods in specific applications and the process drew sufficient research atten...... hiện toàn bộ
Measurement of Thermal Conductivity of Triaxial Braided Composites
SAGE Publications - Tập 42 Số 12 - Trang 1159-1177 - 2008
Shirin Kiani, W. S. Chan, A. Haji‐Sheikh
This article presents the measured thermal conductivity of tri-axial braided graphite/epoxy composites. An apparatus was designed for measuring the temperature at different locations with applied heat flux on a tri-axial braided composite sample. From the measured temperatures, the out-of-plane thermal conductivity, Kzz was calculated by using one-dimensional Fourier'...... hiện toàn bộ
Dynamic Testing of Composite Laminates with a Tensile Split Hopkinson Bar
SAGE Publications - Tập 34 Số 4 - Trang 260-273 - 2000
Hamid Eskandari‐Naddaf, J.A. Nemes
A tensile version of the split Hopkinson bar, suitable for dynamic testing of laminated composite materials, is introduced. A pulse duration of 200-250 microseconds and peak strain rates of up to 350 s5l are obtained. Tests performed on a quasi-isotropic lay-up of graphite-epoxy show good repeatability. To determine the significance of rate-dependency, static tests were also performed usi...... hiện toàn bộ
Saint-Venant Effects in the Iosipescu Specimen
SAGE Publications - Tập 32 Số 22 - Trang 1986-2015 - 1998
Fabrice Pierron
The main purpose of this paper is to explain the shear strain differences observed between the two faces of certain Iosipescu specimens. The different parasitic moments that can act on the specimen are investigated and their effects assessed. Different Iosipescu fixtures from the literature are checked for these parasitic moments and it is shown that modification of the Wyoming fixture ca...... hiện toàn bộ
Non-Linear Deformation and Failure Behavior of Carbon/Glass Hybrid Laminates
SAGE Publications - Tập 21 Số 5 - Trang 396-420 - 1987
Kiyohisa Takahashi, Tsu‐Wei Chou
An incremental analysis predicting the nonlinear stress-strain relations of laminated composites has been developed. Stress increments corresponding to small increments in the uniaxial tensile or compressive strain are obtained by the laminate theory, in which the anisotropy of fibers and the elastic interaction among fibers have been taken into account. Nonlinear shear stress-strain rela...... hiện toàn bộ
Preparation of poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate)/silicon dioxide nanoparticles composite films with large thermoelectric power factor
SAGE Publications - Tập 52 Số 5 - Trang 621-627 - 2018
Endou Liu, Congcong Liu, Zhengyou Zhu, Jingkun Xu, Fengxing Jiang, Tongzhou Wang, Changcun Li
Herein, poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS)/silicon dioxide nanoparticles (SiO2-NPs) composite films were prepared via a simple method by direct vacuum filtration technique. The effect of SiO2-NPs contents on the thermoelectric performance of PEDOT:PSS was investigated systematically. PEDOT:PSS nanofilm without Si...... hiện toàn bộ
