Diffusion and Mechanical Properties of Polyether-Polyurethanes Reinforced with Silica

Thermo-mechanical properties of polymer nanocomposites reinforced with randomly distributed silica nanoparticles- Micromechanical analysis

A three-dimensional micromechanics-based analytical model is developed to study thermo-mechanical properties of polymer composites reinforced with randomly distributed silica nanoparticles. Two important factors in nanocomposites modeling using micromechanical models are nanoparticle arrangement in matrix and interphase effects. In order to study these cases, representative volume element (RVE)...

Adsorption Properties of Thiol-Functionalized Silica Nanoparticles Prepared for Application in Poly(ether sulfone) Nanocomposite Membranes

Isopropyl Myristate-Modified Polyether-Urethane Coatings as Protective Barriers for Implantable Medical Devices

Polyurethane films have potential applications in medicine, especially for packaging implantable medical devices. Although polyether-urethanes have superior mechanical properties and are biocompatible, achieving water resistance is still a challenge. Polyether based polyurethanes with two different molecular weights (PTMO1000, PTMO2000) were prepared from 4,4’-diphenylmethane diisocyanate and p...

بررسی عوامل موثر بر خواص مکانیکی پلی‌یورتان‌ها(علمی-ترویجی)

The aim of this research is investigation of mechanical properties regarding the polyurethanes as the binder of plastic bonded explosives. Due to the great effect of mechanical properties on application of these materials, the influence of Isocyanate/Hydroxyl ratio, crosslink density, the type of curing agent, hard segment and temperature on mechanical properties of these materials were investi...

Flexural and Impact Properties of Stainless Steel based Glass Fibre Reinforced Fibre Metal Laminate under Hygrothermal Conditioning

Fibre metal laminates (FMLs) have appeared as the most suitable materials for shipbuilding, aeronautical and aerospace applications due to their superior mechanical properties over traditional materials. In this paper, degradation in flexural and impact properties of glass fibre/epoxy composite (GF/E composite) and stainless steel glass fibre/epoxy fibre metal laminate (SS FML) due to hygrother...
