Weathering Degradation of Polylactide / Montmorillonite Nanocomposites



GAURI, KL; TAMBE, SS; CANERSALTIK, EN (Springer Science and Business Media LLC, 1992-01-01)
To the exclusion of other major atmospheric pollutants, sulfur dioxide is mainly responsible for attack upon dolomite. This article characterizes Laurel Dolomite on the basis of composition, texture, and porosity; describes the mechanism of the SO2 reaction with dolomite; and develops two equations for the prediction of the rate of decay of dolomite. Over a period of 120 yr nearly 3.57 mm surface reduction at protected areas and 0.915 mm surface reduction at unprotected surfaces of a building in Louisville ...
Weathering degradation performance of PLA and its glass fiber reinforced composite
Varsavas, S. Deniz; Kaynak, Cevdet (2018-06-01)
The objective of this study was to explore the degree of improvement in the resistance of biodegradable polylactide (PLA) structure against atmospheric weathering (outdoor) conditions when reinforced with only 15 wt% E-glass fibers (GF). For this purpose, both neat PLA and PLA/GF composite specimens were exposed to accelerated weathering conditions of both UV-irradiation and moisture cycles in accordance with ISO 4892-3 standards for various periods until 400 h. Many characterization techniques used reveale...
Weathering and Excavation Effects on the Stability of Various Cut Slopes in Flysch-Like Deposits
Ersöz, Timur; Topal, Tamer (2018-12-01)
Cut slopes are very sensitive to weathering because of disturbed rock mass and topographical condition by excavation. During and right after an excavation process of a cut slope, weathering and erosion may act on this newly exposed rock material and mass. These acting on the rock may degrade and change its engineering properties and the stability of the cut slope in its engineering lifetime. In this study, weathering and excavation effects on stability of sixteen cut slopes in flysch-like deposits at North ...

Icing on wind turbine blade under various atmospheric conditions
Yırtıcı, Özcan; Özgen, Serkan; Tuncer, İsmail Hakkı (2017-09-30)
It is important to predict the ice shape with amount of accreted mass on the surface of turbine blade in order to design and develop de/anti-icing systems for wind turbines located in cold climate regions. Ice accretion on the blades change the initial shape and this cause alteration in the aerodynamic characteristic of the blades. To this end, icing module combined with the BEM method to predict the shape of the iced blade sections of the turbine blade under atmospheric icing conditions. The obtained resul...
