Abstract: Carbon fiber (CF) reinforced composites are a high-performing and highly utilized material system historically used in aerospace. As the cost of CF decreases, other industries, such as automotive and energy generation, seek to adopt CF composites into their applications. A sudden increase in CF demand may create supply chain issues if the adoption happens without scaling up the CF production. A solution for reducing the reliance on CF is to substitute some portion of the CF content with another fiber type without significantly reducing the material properties. When multiple fillers are introduced into a composite system, the materials system is often referred to as a hybrid composite and in this case a CF-based hybrid composites as CF is the dominant filler type. To further relieve reliance on CF and with sustainable manufacturing becoming more prominent in industry, mechanically recycling can be employed to replace all or a percentage of the virgin material content which will further aid in reducing the reliance on virgin CF and decrease overall material costs. Here, the effect of mechanical recycling on, mechanical properties, conductive properties, and cost of the CF-based hybrid composite system is explored to understand the feasibility of re-manufacturing the recycled CF-based hybrid composite. The change in material properties with varying recycled content is assessed to determine allowable recycled content for a given application with respect to cost. By determining the properties, degradation mechanisms, and cost based on recycled content, a case is made for utilizing recycled CF-based hybrid composites to reduce cost and reliance on CF.
