Polybenzoxazines (PBZs), relatively new class of polymeric phenolic resins with various outstanding characteristics such as minimal water absorption, high char yield, high glass transition temperature, high tensile strength, and excellent chemical and thermal stability can be utilized as a promising matrix material for Natural Fiber Composites (NFCs) .Cardanol is a major constituent of the cashew nut shell liquid (CNSL) which is an agricultural by-product abundantly available in many parts of the world, particularly in ASEAN countries. Compared to conventional phenolic resins, cardanol based polymer has improved flexibility due to the internal plasticization of the long chain, which provides a better processability. This proposed research aims to synthesize cardanol based benzoxazines and investigate the incorporation of active promoters with hope to expand the application of PBZs in NFCs.
