Nonlinear buckling of axially compressed FG‐GRCL stiffened cylindrical panels with a piezoelectric layer by using Reddy's higher‐order shear deformation theory
Polymer Composites - Tập 43 Số 11 - Trang 7952-7966 - 2022
Vũ Hoài Nam, Dang Thuy Dong, Cao Van Doan, Nguyen Thi Phuong
AbstractThis paper proposed a new analytical approach for the nonlinear buckling behavior of axially compressed functionally graded graphene reinforcement composite laminated (FG‐GRCL) stiffened cylindrical panels with the piezoelectric layers resting on the Pasternak's elastic foundation in the uniformly distributed temperature change. A design for the reinforcement of stiffened cylindrical panel... hiện toàn bộ
Preparation and characterization of thermally conductive thermoplastic polyurethane/h‐BN nanocomposites
Polymer Composites - Tập 35 Số 3 - Trang 530-538 - 2014
Emrah Çakmakçı, Çiler Koçyiğit, Selma Çakır, Ali Durmuş, Memet Vezi̇r Kahraman
Polyurethane nanocomposites are versatile engineering polymers with unique properties. In this study, nano hexagonal boron nitride containing thermoplastic polyurethane elastomers were prepared via melt blending and hot‐pressing techniques. The nanocomposites were characterized using Fourier transform infrared, differential scanning calorimetry, thermal gravimetric analysis, tensile tests, and the... hiện toàn bộ
Flexural properties of S‐2 glass and TR30S carbon fiber‐reinforced epoxy hybrid composites
Polymer Composites - Tập 33 Số 5 - Trang 773-781 - 2012
Chensong Dong, John Duong, Ian J. Davies
AbstractA study on the flexural properties of hybrid composites reinforced by S‐2 glass and TR30S carbon fibers is presented in this article. Test specimens were made by the hand lay‐up process in an intraply configuration with varying numbers of glass/epoxy laminas substituted for carbon/epoxy laminas. These specimens were then tested in the three point bend configuration in accordance with ASTM ... hiện toàn bộ
Kinetic studies of thermoset cure reactions: A review
Polymer Composites - Tập 18 Số 2 - Trang 157-168 - 1997
Azizeh‐Mitra Yousefi, Pierre G. Lafleur, R. Gauvin
AbstractThis article presents a review of the kinetic studies on the cure reactions of thermosetting resins. The emphasis is placed on those conducted using the thermal analysis by differential scanning calorimetry. Two important categories of kinetic models are discussed and some existing parameter estimation techniques are presented. A variety of factors affecting the cure reactions, including t... hiện toàn bộ
Acrylonitrile butadiene styrene composites reinforced with nanozirconia and PTFE: Mechanical and thermal behavior
Polymer Composites - Tập 39 Số S3 - 2018
D. Amrishraj, T. Senthilvelan
Acrylonitrile butadiene styrene composites reinforced with varying contents of PTFE and nanozirconia have been prepared by employing twin screw extrusion technique followed by compression molding. Mechanical properties such as hardness, tensile strength, tensile modulus, elongation at break, impact strength, flexural strength, and flexural modulus have been determined by conducting various mechani... hiện toàn bộ
Aging characteristics of glass fiber‐reinforced polyamide in hot water and air
Polymer Composites - Tập 39 Số 4 - Trang 997-1005 - 2018
Klaus J. Geretschläger, Gernot M. Wallner
This article focuses on the accelerated aging behavior of a glass fiber‐reinforced and heat stabilized polyamide grade. Accelerated aging of injection molded specimens was achieved by hot air exposure (HAE) and pressure cooker testing (PCT) at elevated temperatures. For both aging routines, characteristic aging indicators were found. For hot air exposure, the carbonyl index obtained from infrared ... hiện toàn bộ
Processing of microcellular polyester composites
Polymer Composites - Tập 6 Số 3 - Trang 175-180 - 1985
Jae Ryoun Youn, Nam P. Suh
AbstractA new method of producing microcellular polyester composites is developed. The microcellular foam which is produced by supersaturating the polyester resin with nitrogen is cured by dielectric heating. The lightweight composite contains about 10 μm size bubbles. By substituting the microcells for the particulate fillers of the conventional composites, the weight of the composite is reduced ... hiện toàn bộ
Rheological behavior and mechanical properties of PVC/MAP‐POSS nanocomposites
Polymer Composites - Tập 31 Số 10 - Trang 1822-1827 - 2010
Jungang Gao, Yonggang Du, Cuifang Dong
AbstractThe polyhedral oligomeric silsesquioxanes which contains methylacryloylpropyl groups (MAP‐POSS) was synthesized. The MAP‐POSS/PVC nanocomposites were prepared. The influences of composition, shear rate' shear stress on melting rheological behavior of MAP‐POSS/PVC nanocomposites were discussed. The dynamic mechanical properties, mechanical properties, and morphology were determined by DMA, ... hiện toàn bộ
Multifunctional properties of polyester fabrics modified by corona discharge/air RF plasma and colloidal TiO2nanoparticles
Polymer Composites - Tập 32 Số 3 - Trang 390-397 - 2011
Darka Marković, Zoran Šaponjić, Ricardo Molina, Marija Radoičić, Jordi Esquena, Petar Jovančić, Jovan M. Nedeljković, Maja Radetić
AbstractIn this study the possibility of tailoring the textile nanocomposite materials based on the polyester fabric and TiO2nanoparticles that can simultaneously provide desirable level of antibacterial activity, UV protection, and self‐cleaning effects with long‐term durability was investigated. To enhance the binding efficiency of colloidal TiO2nanoparticles, the surface of polyester fabrics wa... hiện toàn bộ
Influence of polyhedral oligomeric silsesquioxanes on thermal and mechanical properties of polycarbonate/POSS hybrid composites
Polymer Composites - Tập 32 Số 9 - Trang 1343-1351 - 2011
Hualun Cai, Kai Xu, H. Liu, X. Liu, Zhiang Fu, M.C. Chen
AbstractTwo types of silsesquioxanes were synthesized by hydrolytic condensation reaction, and then were incorporated into polycarbonate (PC) matrix by melt blending to prepare PC/POSS hybrid composites. The study of morphology of the composites showed that octaphenylsilsesquioxane (PH‐POSS) exhibited partial compatibility with PC matrix, while 3‐glycidyloxypropylsilsesquioxane (EP‐POSS) could rea... hiện toàn bộ
