Abstract

Two procedures of resin moulding powder preparation were evaluated. Their results are discussed on the basis of their tensile properties for moulded dumb-bells. The best procedure was then implemented for future work on phenolated pitch/ligin systems. Mouldings of different resin contents made with these phenolated resins were tested and the most promising catalytic systems were then selected for the development of a suitable phenolated pitch/lignin resin material. the solubility results of the phenolated material indicated that high temperature phenolation in the presence of catalyst proceeded without detrimental side effects (i.e. charring).
