ESTRADA-CINGUALBRES, Roberto Andrés et al. Resistance to wind of light covers of fiber cement and composite of polyester and fiberglass. Ingeniería Mecánica [online]. 2020, vol.23, n.2  Epub Aug 01, 2020. ISSN 1815-5944.

Asbestos cement is a material used in the production of lightweight roof tiles. It has been shown to be highly toxic and carcinogenic, which is why it is necessary to obtain new materials that do not present this problem, with equal or superior physical-mechanical characteristics, which can be used in the manufacture of roof tiles for different construction works. The objective of this research has been the mechanical characterization of the wavy type tile based on a polymeric matrix reinforced with fiberglass and the comparison of the resistive behavior through the Finite Element Method of light roofs built with this material and those made of asbestos cement, subjected to the wind loads. The critical crack values were obtained for the tiles made of both materials. The fiberglass reinforced tile presented more strength and a larger critical crack size.

Keywords : finite elements; fracture mechanic; light covers; winds; asbestos cement; composite materials.
