Obtenção e caracterização de compósito polímero-SiC

Abstract

This work aims to obtain a composite of PBT-SiC and to characterize its properties, the proportion of the composite mixture was defined according to the law of the mixtures, two compositions were produced with 5% and 10% SiC. Two molds were made, one for tensile test specimens and one for flexure, the specimens were tested according to ASTM D638-03 and ASTM D792 respectively. The characterization tests were the determination of the specific mass, tensile test and flexural test; from these tests, it was possible to obtain the tensile modulus and flexural modulus, modulus of elasticity and tenacity. The composites of 10% and 5% PBT-SiC showed lower flexural modulus values than pure PBT, higher modulus of elasticity, and lower modulus of tenacity, evidencing the embrittlement of the PBT matrix due to the addition of SiC.
