Phenolic resin infiltration and carbonization of cellulose-based bamboo fibers

Abstract

Cellulose-based bamboo fibers were infiltrated with phenolic resin with assistance of vacuum and carbonized at 700, 900, and 1200 degrees C. The effects of resin infiltration on the chemical composition, thermal shrinkage, weight loss, and the thermal stability of carbonized bamboo fibers were explored. It was noted that phenolic resin infiltration contributed not only to the decrease of thermal shrinkage and weight loss occurring in the furnace during carbonization but also to the increase of carbon contents and thermal stability of carbonized bamboo fibers, with increasing carbonization temperature. The fiber morphology revealed that the cellular structure of bamboo fiber with resin infiltration was retained after carbonization. (c) 2013 Elsevier B.V. All rights reserved.
