According to the Japan Chemical Daily, a research team from the National Institute of Advanced Industrial Science and Technology (AIST) led by Yoshiki Sugimoto has developed a high-performance ceramic-coated fiber, which has become a new method for carbon fiber recycling
.
Although carbon fiber reinforced plastic (CFRP) offers the advantages of combining strength with lightness, it has proven difficult to recycle and often ends up in landfills
.
As a method of recycling carbon fibers, carbon fibers can be recovered by thermally treating or chemically decomposing the matrix resin
.
What the AIST research team has done is develop a technique that mixes and fires carbon fibers about 200 micrometers in length with silicone to produce high-performance ceramic-coated fibers
.
The fibers brought about by this technology have higher heat resistance than ordinary carbon fibers and can withstand high temperatures of 100 to 200 degrees Celsius
