Recyclability and Embodied Energy of Advanced Polymer Matrix Composites

2023

AI summary Read the abstract

This paper examines the recyclability and embodied energy of advanced polymer matrix composites used in aerospace and automotive applications. Improving recycling of carbon fiber composites prevents these materials from becoming persistent microplastic debris when components reach end of life.

Recycling of advanced composites made from carbon fibers in epoxy resins is essential for two primary reasons. First, the energy necessary to produce carbon fibers is very high and therefore reusing these fibers could greatly reduce the lifecycle energy of components which use them. Second, if the material is allowed to break down in the environment, it will contribute to the growing presence of microplastics and other synthetic pollutants.Recyclability and Embodied Energy of Advanced Polymer Matrix Composites discusses current recycling and disposal methods—which typically do not aim for full circularity, but rather successive downcycling—and addresses the major challenge of aligning fibers into unidirectional tows of real value in high-performance composites.Click here to access the full SAE EDGETM Research Report portfolio.

Influence of carbon nanomaterials on microplastic release from polymer composites

AI summary Read the abstract

Plastics are increasingly blended with carbon-based materials like graphene and carbon nanotubes to make them stronger, but this review of existing research finds that these additives can either reduce or worsen the shedding of microplastics, tiny plastic particles now found in our air, water, and even our bodies, depending on the specific materials and conditions involved. Because results vary so much between studies, scientists don't yet have a clear answer on whether these popular high-tech plastics are safer or riskier for microplastic exposure, highlighting the need for standardized testing before we can know their true impact on human health.
