The research involves using phenol – formaldehyde (Novolak) resin for making Novolak compact with hexamethyltetraamine (HMTA ) in different ratio (15%) and (20%) by weight , also this work involves preparing composite material by using Novolak as a matrix , while flint was used as resin forcing material and making composite compact with ratio of hardener (15%) and (20%) by weight. The research was studied some of thermal properties such as thermal conductivity and thermal Erosion resistance. The results show that the flint and increasing the (HMTA) leads to increase thermal Erosion resistance and thermal conductivity . The results show that the immersion in water leads to increase thermal conductivity .
