The properties of the filled polymer compositions largely depend on the nature and surface properties of the fillers- basalt fiber. The possibility of modifying the surface of the basalt fiber with commercial polyhexamethyleneguanidinehydrochloride and non-commercial polydiethyleneaminoguanidine - appretes, were demonstrated for the first time.
The main aim of this study is to predict the elastic and damping properties of composite laminated plates. Some approximate methods for the stress state predictions for laminated plates are presented. For simple uniform bending and transverse loading conditions, this problem has an exact elasticity solution. This paper presents a new stress analysis method for the accurate determination of the detailed stress distributions in laminated plates subjected to cylindrical bending.
This study aims to predict the sound transmission properties of composite layered plates structures in the lower frequency range. In present paper a novel procedure to derive the sound isolation parameters for layered plates is under discussion. This paper presents a new stress analysis method for the accurate determination of the detailed stress distributions in laminated plates subjected to cylindrical bending. Some approximate methods for the stress state predictions for laminated plates are presented here.
The paper is devoted to the investigation of efficiency of reinforced concrete column strengthening using pultruded carbon fiber plates.
The influence of model biological medium on the properties and structure of epoxy-polyurethane (EPU) ferrocene compositions has been investigated by physical-mechanical IR-spectroscopic and X-ray methods. It has been established that the EPU compositions biodegrade most intensively after 1 month of incubation, accompanied by a decline in strength at 80–92 % break.
