The fabricating process for composite by autoclave has a high cost and it is necessary a long cycle time until the part is ready and it is conceivable to open the autoclave. Instead, hot compression molding may be a quick prepare, that does not require a long handle time and the quality of the pieces is comparable to the parts made in autoclave. The hot compressing molding could be considered out-of-autoclave (OOA) cured process. OOA is broadly utilized due to be quicker and less expensive in relation to autoclave, past to be conceivable to fabricate complex formed parts and diminish auxiliary stages. For this purpose, it was utilized a prepreg made with epoxy-carbon fiber, that is utilized for autoclave prepare, but in this study it has been utilized for OOA process, to see in case it is conceivable to reach comparable or way better comes about compared with the tests from autoclave. The cover was fabricated through hot compression molding instep the normal process for this fabric, as autoclave. DSC tests were carried out to analyze the Tg (glass transition temperature) in arrange to confirm if there was a few polymerization reaction and confirm the combination of parameters that was proposed within the work arrange. The morphological tests were made to confirm if there was porosity within the composite, due to the fabricating process, and confirm in the event that the layers were well compacted. |
