Preparation and characterization of PBT nanocomposites compounded with different montmorillonitesPolymer Engineering and Science - Tập 44 Số 6 - Trang 1012-1018 - 2004
Domenico Acierno, Paola Scarfato, Eugenio Amendola, Giuseppe Nocerino, Giovanna Costa
AbstractBecause of their superior mechanical and thermal properties, light weight, and favorable cost/performance ratio, nanocomposite materials appear to be suitable replacements for metals and alloys in many industrial applications in fields such as automotive, structural plastics, electronics, packaging, and so on (1). The technological relevance of this large‐s...... hiện toàn bộ
Measurement of thermal conductivity of polymer melts by the line‐source methodPolymer Engineering and Science - Tập 30 Số 2 - Trang 65-70 - 1990
Hubert Lobo, Claude Cohen
AbstractAn apparatus has been developed for the measurement of thermal conductivity of polymer melts. Based on the transient “line source method,” it is ideally suited to these materials because measurements can be made quickly, before the onset of thermal degradation. Also, little or no sample preparation is required. A number of commercial polymers have been test...... hiện toàn bộ
The role of the interface in adhesion phenomenaPolymer Engineering and Science - Tập 17 Số 7 - Trang 467-473 - 1977
K. L. Mittal
AbstractThe role of the interface in adherend‐adherate combinations and in the strength of adhesive joints has been examined. For the former systems, practical adhesion (as determined experimentally, for example, by peel, tensile, or shear strengths) is a function of basic adhesion (determined by intermolecular, interactions such as van der Waals, electrostatic, or...... hiện toàn bộ
Thermoset characterization for moldability analysisPolymer Engineering and Science - Tập 14 Số 3 - Trang 231-239 - 1974
Musa R. Kamal
AbstractThe injection molding of thermosetting compounds involves complex interactions between material parameters and molding conditions, on one hand, and moldability and the ultimate properties of molded parts, on the other hand. The main role of the molding variables may be related to their effects on the cure time and temperature and on the flow and thermal phe...... hiện toàn bộ
Comparative study of the cure kinetics of an unsaturated polyester resin using different proceduresPolymer Engineering and Science - Tập 36 Số 6 - Trang 835-851 - 1996
Josep María Salla, Xavier Ramis
AbstractThe cure kinetics of an unsaturated polyester resin were studied by differential scanning calorimetry (DSC), and different dynamic and isothermal procedures were compared. It was established that the isothermal kinetic analysis through the isoconversional adjustment lnt = A + E/RT is the method that offers the most accurate result...... hiện toàn bộ
On the characterization of nonlinear viscoelastic materialsPolymer Engineering and Science - Tập 9 Số 4 - Trang 295-310 - 1969
R. A. Schapery
AbstractStarting with specific constitutive equations, methods of evaluating material properties from experimental data are outlined and then illustrated for some polymeric materials; these equations have been derived from thermodynamic principles, and are very similar to the Boltzmann superposition integral form of linear theory. The experimental basis for two equ...... hiện toàn bộ
The design and performance of a new miniature mixer for specialty polymer blends and nanocompositesPolymer Engineering and Science - Tập 44 Số 5 - Trang 868-879 - 2004
O. Breuer, Uttandaraman Sundararaj, Roger Toogood
AbstractA novel miniature mixer called the “Alberta Polymer Asymmetric Minimixer” (APAM) was designed, built and tested. In this study, polymer blends and nanofiber composites were compounded using a total of approximately 2 grams per sample. This mixer has a unique, asymmetric design consisting of a varying clearance between the rotor blade tips and the cup wall, ...... hiện toàn bộ
