This study aims to reuse the waste of uncured composite prepreg scraps from the ply cutting manufacturing process in the aerospace industry, avoiding the resin loss, waste disposal and expenses with its incineration.Carbon fiber/F155-epoxy resin laminates were produced by randomly positioned scraps, with different sizes and shapes, and characterized by tensile, compression, interlaminar shear (ILSS), and flexural tests. Tensile, compression, and flexural strengths of produced laminates decreased...

This study aims to contribute to sustainability by proposing the reuse of composite prepreg scrap as an added value from discards. The research evaluates the microstructure and mechanical properties of laminates processed by the reuse of uncured carbon fibre/F155-epoxy resin prepreg scraps, waste from the ply cutting area of an aeronautical industry. The composite scraps were used as collected and were randomly positioned to produce laminates to be cured at an autoclave. The mechanical character...

In this study, the thermal behavior of three families of carbon fiber/epoxy resin laminates, exposed to multiple thermal cycles, were evaluated. Thermogravimetric (TGA) and dynamic mechanical (DMA) analyses were used. This paper aims to consider the use of carbon fiber/epoxy prepreg scraps - a noble material in the aircraft industry, by comparing the thermal behavior of one laminate manufactured with prepreg scraps (laminate R), a laminate manufactured with commercial prepreg (Laminate A) and a ...

The composite prepreg waste is still an environmental challenge. In the last decade, several researchers have been studying the recycling and reuse processes of composite components, mainly to use in secondary (non-structural) components. In this paper, uncured aerospace grade prepreg scraps resulted from the production waste were used to manufacture laminates. The carbon reinforcement of the prepreg presented plain weave style fabric. To manufacture the laminates the hand-lay up process was use...
