Anti-high speed impact properties of polyimide fiber/bismaleimide resin composites

open access: yesCailiao gongcheng, 2021
The polyimide fiber/ bismaleimide resin composites were prepared by the autoclave molding process. Effects of volume fraction of polyimide fiber and ambient temperature on the high speed impact properties were investigated using the air cannon impact ...

High speed impact properties of carbon fiber/epoxy resin composites

open access: yesCailiao gongcheng, 2019
The carbon fiber/epoxy resin composites were prepared by the resin transfer molding (RTM) process. Effect of resin toughness and carbon fiber type on the high speed impact properties was investigated using the air cannon impact test.

Application of hydrophobic fluorinated silicon oxide nanoparticle coating on electrodynamic screen (EDS) films for enhancing self-cleaning function of solar collectors [PDF]

open access: yes, 2020
Optical surfaces, which are exposed to outdoor environmental conditions, are susceptible to dust deposition. Sunlight incident on the surface of photovoltaic (PV) modules is attenuated by the dust layer accumulation on the front surface of the modules ...

Development of Mucoadhesive Gel Microbicide to Target Mucosal HIV Reservoirs [PDF]

open access: yes, 2014
The wide use of microbicide is mainly depends on its effectiveness, less frequent application, ready availability and most importantly cost. The aim of this work was to develop affordable microbicide mucoadhesive gel formulation of synthetic anti HIV ...

Band splitting and Modal Dispersion induced by Symmetry braking in Coupled-Resonator Slow-Light Waveguide Structures

open access: yes, 2009
We study the dispersion relations in slow-light waveguide structures consisting of coupled microdisk resonators. A group theoretical analysis of the symmetry properties of the propagating modes reveals an interesting phenomenon: The degeneracy of the CW ...

With No Deliberate Speed: The Segregation of Roma Children in Europe [PDF]

open access: yes, 2016
In this study, by taking the advantage of both inorganic ZnO nanoparticles and the organic material chitosan as a composite seed layer, we have fabricated well-aligned ZnO nanorods on a gold-coated glass substrate using the hydrothermal growth method ...

Response Functions to Critical Shocks in Social Sciences: An Empirical and Numerical Study

open access: yes, 2004
We show that, provided one focuses on properly selected episodes, one can apply to the social sciences the same observational strategy that has proved successful in natural sciences such as astrophysics or geodynamics. For instance, in order to probe the
