Estudio in vitro de la resistencia a la flexión de tres marcas comerciales de postes de fibra de vidrio.

The aim of this in vitro investigation was to know the flexion resistance of three trademarks of fiberglass pads on the market. To this purpose, a test of the flexion resistance of 3 groups of fiberglass pillars was carried out. The methodology used was observational, descriptive, experimental design and cross-cutting. In this study, a total of 45 samples were used, divided into 3 groups: 15 AAA Fiber Post, 15 Superpost and 15 Reforpost Angelus glass fibers were tested in the Laboratory of Strength and Vibration Analysis at the Faculty of Engineering of the National Polytechnic School to determine the 3-point flexion resistance for which the Universal Testing Machine was used. Through this test, it was possible to determine the maximum curve of flexion in Newton (N) exercised by the machine at each pole to calculate the flexion resistance measured in Megapascals (MPa), thus obtaining the following results: AAA Fiber Post (645,2 MPa), Superpost (433,0 MPa) and Reforposte Angelus (711,1 MPa). For this reason it was concluded that the Reforpost Angelus glass fiber poles are the most resistant to bending, followed by the AAA Fiber Post poles and the least resistant the Superpost Brand poles.
