FINELY DISPERSED COMPOSITE BINDER FOR REINFORCING SOILS BY INJECTION METHOD

HTPB-Polyurethane: A Versatile Fuel Binder for Composite Solid Propellant

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

Phase field simulations of grain growth in two-dimensional systems containing finely dispersed second-phase particles

The pinning effect of small incoherent particles on grain growth in two-dimensional polycrystalline systems has been simulated using a phase field model. Simulations were performed for different sizes and area fractions of the second-phase particles and for two types of initial microstructure and different initial grain sizes. The grain size distribution and the number of particles located at g...

Glass transition temperature changes of melt-blended polymer nanocomposites containing finely dispersed ZnO quantum dots

We report the linear increase in the glass transition temperature, Tg, with nanofiller weight content. ZnO quantum dots dispersed by melt-blending in a poly(methyl methacrylate) host were characterized by differential scanning calorimetry and dynamic mechanical analysis showing that the Tg of the system is described by a power law of the interparticle distance, hp, where the percolation exponen...
