Abstract:
Silica has played a key role in the development of composite materials due to its unique properties and versatility such as chemical inertness, high melting point, among others, which makes it have several application possibilities. This article presents an analysis of the behavior of silica when used as reinforcement, highlighting its mechanical properties to contribute to the enhancement of composite performance. Additionally, the method used for sample preparation, the incorporation of silica into the polymeric matrix, and its implications on mechanical behavior will be discussed. Eight specimens were fabricated for each formulation integrated with epoxy resin using a DGEBA/DETA system with a phr of 16, with silica incorporation levels of 5%, 10%, 15%, and 20%. The ASTM D790 standard was employed for the test, at a rate of 1,3 mm/min.
