Resumo:
Polymeric matrix composites are often exposed to environmental conditions that lead to their degradation over time. In order to understand the effects of aging on these composites, they can be subjected to conditions that accelerate their aging to study the changes undergone by the material. Understanding the effects of accelerated aging allows for further research aimed at predicting and mitigating failures, thus ensuring greater durability and safety. In this context, conducting accelerated aging studies on composites becomes essential to simulate and analyze the physical and chemical changes that occur in the material, and correlate them with the conditions to which they have been exposed. This work proposes to investigate accelerated aging in glass fiber - epoxy matrix composites, in order to understand degradation mechanisms and also identify strategies for protection and maintenance of the composites. Aged and unaged glass fiber - epoxy composite samples with impact damage were investigated by interlaminar shear strength (ILSS) tests and results were compared.
