Abstract:Unmanned Aerial Vehicle (UAV) is a military product used extensively in the last decade. The successful outcome has expedited the migration of this technology to the civil market. Nowadays, UAVs can perform photogrammetry, inspection of civil buildings, delivering goods and assisting in rescue missions. The results depend on multiple factors, such as identification of flight mission, choice of UAV type and control algorithms. There are various types and sizes of UAV. The quadrotor is the one of most affordable… Show more
The task of developing durable and effective building materials for protection against aggressive environments is urgent. One of the ways to increase the durability of buildings and structures is the use of polymer composite materials during their construction. In addition, the urgent task of recycling waste from construction and chemical industries also has to be considered. Determination of rational compositions of composite materials manufactured by compression and vibrocompression methods is of considerable interest. The problems of obtaining compositions of polymer composites based on the use of a modifying additive - a plasticizer (organosilicon varnish KO-922) and asbestos-containing fillers based on waste from construction and chemical industries are addressed. An analytical and graphical method for calculating the compositions of epoxy composite materials based on production wastes has been developed. Rational formulations based on modified epoxy binder have been obtained. The nomograms make it possible to make a practical choice of one or another filler composition for given conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
