Resumen:
The present work aimed to determine the maximum tensile, flexural and compressive strengths of the glass fiber reinforced polyester resin for thicknesses ranging from approximately 1.5 to 6.5 mm, as well as to study the apparent specific mass variation, porosity intergranular, angle of repose, grain-grain friction coefficient and grain-wall friction coefficient of maize grains as a function of their moisture content of 9 to 20% dry basis, besides conducting experimental tests of
Determination of the horizontal and vertical pressures in a prototype silo in the loading and unloading operations of granular products (maize), comparing them with the pressures obtained with the equations proposed by Janssen and Reimbert. It was concluded that the maximum tensile, flexural and compressive strengths of the. fiberglass ranged from 544.7 to 1,119.7 kgf / m2; 1,394.2 to 2,618.5
from 405.05 to 1,017.34 kgf / m2, respectively, and that the intergranular porosity, the angle of repose, the grain-grain friction coefficients and the grain wall of the corn grow with increasing moisture content from 9 to 20% dry basis, with the mass
The apparent specificity of this product decreases with increasing
humidity for the same range as above. The experimentally obtained horizontal pressures are lower than those proposed by the Janssen and Reimbert and
that the overpressures in this experiment occurred mainly
at the corn discharge on the right side of the material discharge.
