The challenge of determining nine elastic characteristics orthotropic woven composites is considered. Using a test example, the influence transverse on results stress-strain state analysis composite structures assessed. To determine constants an composite, we propose to use representative volume materials repeated structure. features creating finite element model layered are properties kinemati...

Composites composed of a chlorophyll-a derivative and Ti3C2T x MXene recently showed promising results as photocatalysts for the hydrogen evolution reaction. Herein, this type composites is prepared by using layered material via an HCl@LiF etching technique, instead previously adopted HF technique. The performance H2 evolution, therefore, fourfold increase in photocatalytic system, compared wit...

The purpose of this study was to investigate the radiation attenuation effect due reflection and refraction that occurs when passes through composite material simulation. gamma-ray shielding ability composites with different structures, such as layered composite, fibrous particle-added composites, compared. For regardless thickness, structure could not be seen. simulated coefficient found than ...

BACKGROUND AND OBJECTIVES: This study aims down to evaluate the ability of chloride magnesium- aluminium- layered double hydroxides (4:1) for nitrate adsorption from the soil solution in successive cropping periods. METHODS: The study was conductedunder long-term cropping periods, including first crop): bell pepper; second crop: mentheae; third crop: cher...

applications of thermoplastic composites have developed extensively. the thermoplastic composites in comparison with the thermoset composites have many advantages. thermoplastic composites can be melted and remolded many times. the duration of manufacturing process of these composites is short, producing very tough material, and the welding ability and multiple recyclings are their further adva...

The paper presents a comparative analysis of methods and results calculating the physical mechanical characteristics single-layered multi-layered polymer composite materials (PCM). object study is which consists epoxy binder carbon fiber reinforcements. principle multiscale modelling applied to determine composite. Within framework this study, representative volume element (RVE), structure corr...
