    Abstract: In the current research, composite content three materials polyester resin as a matrix and the
reinforcement material with the percent of 2: x for sawdust soda lime glass, respectively where (x = 0, 3, 6, 10,
14%). All the samples have prepared by hand layup process. In this study was investigated the thermal
conductivity and some of the mechanical properties as a tensile strength impact strength, compressive strength,
hardness and flexural strength. The factors of tensile strength, compressive strength and flexural strength
appeared clear improvement at percent 2:6. The rest studied factors appeared different behaviors.
