For the development of engineering projects, the adequate selection of materials is crucial, especially concerning their mechanical properties. In practical applications, these properties can significantly be affected by the material in service undergoing some type of degradation. With the exposure to the external environment in service, a significant degradation is the one caused by the incidence of ultraviolet radiation (UV). This type of radiation has enough energy to break the chains of polymeric materials. Thus, it is important to study the effects caused by UV radiation on the behavior of this material class. To simulate this exposure, standardized degradation chambers are often used. However, this equipment is generally sold in high cost. Without equipment that simulates UV radiation, many research projects are unfeasible. In this work, it is aimed to present a UV chamber design using low-cost UV lamps for the degradation of composite materials. In addition to being more affordable, the chamber allows an accelerated degradation sufficient to carry out experimental academic research about UV degradation in polymeric materials.
