DIGITAL DESIGN OF THE REINFORCEMENT OF THE COMPOSITE MATERIAL NEW OF THE OIL FILM TRAWLING EQUIPMENT LOCATED IN OPEN AQUATIC HABITAT

Water pollution with oil residues is a particularly important and difficult problem to prevent and solve. The ecological consequences of black tides have proven to be particularly serious and even catastrophic for marine ecosystems. In this sense, the limitation and concentration represent the optimal response action to hydrocarbon pollution. The aim of the work was to digitally design a woven textile reinforcement used as a matrix of the composite material from which the freeboard and skirt of the floating surface boom modules are made, which are used dynamically in the open sea for towing the pollutant film. In order to establish the optimal values of the engineering characteristics of the composite material, respectively: strength and elongation at break in the longitudinal and transverse direction, mass, resistance to the thermal regime of water specific to the closed sea, without communication and to the upwelling phenomenon, a specialized software was used. The reinforcement density values were obtained after calculating the stretching force (Laplace's equation) from the composite structure used in dynamic field (impact multiplier 2) and the tensile strength of the material in shock conditions (Brown's formula).
