Abstract

This study aimed to evaluate the physical-mechanical performance and durability of homogeneous sugarcane bagasse particleboards and polyurethane resin based on castor oil; to evaluation of the mechanical behavior of both modular panels of particleboards and reforestation wood by numerical simulation, soft body impact test and application in cattle handling facilities; to study bovine behavior parameters managed in the facility built with modular panels, by measuring body surface temperature and the reactivity of animals. The physicochemical properties and microstructure of the particles of sugarcane bagasse were determined. For homogeneous particleboards both without and with surface coating, the physical and mechanical properties were evaluated before and after natural aging. The evaluation of the mechanical performance of modular panels was performed by means of a numerical simulation, under laboratory conditions by soft body impact test and, in situ, applied to a crowding pen of corral for cattle management. The handled animals had their body surface temperature measured by infrared thermography and their reactivity was measured by the parameters of flight time in crowding pen and behavior score in crowding pen. The homogeneous particleboards of sugarcane bagasse met the regulatory requirements for applications as a structural component. The modular panels showed lower experimental transverse displacement values when measured by the numerical model. The animals handled in the crowding pen of modular panels and conventional wooden boards showed no difference in reactivity parameters, but the average and maximum superficial body temperatures were lower in animals handled the crowding pen with modular panels.
