CARBON FIBER ADVANCEMENTS

In the early 1970s, it was discovered that heating pitch (petroleum or coal based) would produce a high carbon organic precursor that could be used to produce carbon fibers. Pitch-based carbon fibers deliver superior modulus and thermal conductivity but come up short in tensile strength and compression strength as compared to PAN-based carbon fiber.

Continuing research and development on these novel carbon fiber materials in the years that followed led to the innovations that we see today. Carbon fibers from all three precursor types are commercially available today but PAN dominates with well over 90% of carbon fibers being produced from this precursor.

Today's KNOWLEDGE Share Researchers Identify Plastic-Degrading Microbes in Mangrove Soil An international team of researchers has developed a novel method to select bacteria from mangrove soils capable of transforming plastic. This breakthrough offers a potential new approach to tackling plastic waste pollution. By analyzing the effects of polyethylene terephthalate (PET) particles and seawater intrusion on the microbiome of mangrove soil, the team was able to cultivate a collection of PET-degrading microbes. With plastic pollution reaching alarming levels globally, even in remote ocean environments, ecosystems like mangroves—crucial biodiversity hotspots—are under threat from various stressors, including plastic contamination. “Mangrove ecosystems are exposed to significant plastic pollution, and their soils harbor diverse microbial communities, including those with potential plastic-degrading capabilities,” explained Diego Javier Jiménez Avella, a research scientist from the Micr...
