## Abstract The network‐forming behavior, gelation, and vitrification of lignin‐polyether‐copolymer‐epoxide/amine resins were determined using a recently described dynamic mechanical thermal analysis (DMTA)‐based method. Six resins were studied which differed in lignin content, polyether arm length
Carbon fiber composites based on tetrafunctional epoxy resin N,N,N,N-tetraglycidyl-2,2bis[4-(4-aminophenoxy)phenyl]propane modified with cardanol were investigated. The differential scanning calorimetric technique was used to study the curing reaction of the neat resins. The dielectric properties of
