Abstract
Composite materials have become increasingly relevant in different applications, especially in the aerospace field. They are increasingly present in the production of internal components and external ribs of wings in aircraft, leading edge, flaps, landing gear doors, radome of cargo aircraft, structural parts of fighters jet, among others. This article aims to present the analysis of the influence of the cure and post-cure processes of specimens made with glass fiber and polyester resin; to perform post-cure in certain types of specimens; to perform mechanical tests and to analyze the results of the specimens. Four types of specimens will be manufactured, differentiated by the cure and postcure processes. To manufacture the specimens and subject them to the curing process, a laminating bench with temperature control and vacuum use was developed. An autoclave developed at the University of Brasilia was used to perform post-cure treatment. The tests showed different mechanical performances of the specimens and showed that cure and post-cure provide increased mechanical properties of the material.
