Phenolic foams have high fire resistance, thermal stability at high temperature and maintaining performance over a broad temperature range, which have led to a broad range of applications as an insulating material. However, phenolic foam is needed to improve the mechanical properties for more extensive application. These problems can be improved by controlling the cell morphology because the properties of phenolic foam are determined by the cell morphologies such as cell shape, cell wall thickness and cell density. And the cell morphologies are affected by various factors that are viscosity of the phenolic resin, degree of cure before the foaming and the type of particle for reinforcement. In this work, the phenolic foam was fabricated by reinforcing the nano-particles, multiwall carbon nanotube (MWNT) and graphene, to improve the thermal and mechanical properties of the phenolic foam. The optimal weight percent of particle formed the proper cell morphology of the phenolic foam. And optimal aging time before microwave foaming of each particle reinforced phenolic resin were investigated by cure monitoring using a dielectric sensor to obtain the optimal cell morphology. From the experimental results, optimal weight percent of the each carbon nanoparticle was found based on the cell morphology, thermal and mechanical properties of the phenolic foams.
