Diseño y evaluación de mezclas de cemento polimérico como material alternativo para la fabricación de instrumentos musicales

Abstract

This undergraduate thesis presents a study on the viability of using polymer concrete as an alternative material to wood in the manufacture of musical instruments. Mixtures of Portland cement and epoxy resin were designed and evaluated in various proportions, with their mechanical properties analyzed: compressive strength, flexural

strength, density, and elasticity percentage. The results indicate that the 1:1 (cement- resin) mixture provides acceptable properties, with a compressive strength of 25.35

MPa, a flexural strength of 13.8 MPa, a density of 1.46 g/cm3, and an elasticity percentage of 1.76%. Using this mixture, a prototype musical instrument (electric bass guitar) was manufactured, demonstrating its structural viability as an alternative to traditional materials
