Análise de falhas em materiais poliméricos com aplicação de técnicas analíticas

Abstract

This study investigates the failure analysis of polymeric materials using analytical techniques and presenting case studies that demonstrate these applications. Initially, fundamental concepts about polymers and the main factors influencing the occurrence of failures in these materials are introduced. Subsequently, the analytical techniques FTIR, DSC, TGA, SEM XRD, and GC-MS are discussed, addressing their application in polymer characterization and the identification of mechanical, thermal, and chemical failures. The research follows a literature review approach, complemented by case studies developed at Afinko. The results show that the combination of these techniques enables the identification of contamination, degradation, structural variations, and the influence of factors such as the manufacturing history and operating conditions of the components. It is concluded that the integrated analysis of these methodologies is essential for effective failure investigation, enabling quality control and the prevention of new issues while contributing to the development of more reliable polymeric materials.
