Abstract
This study aims to investigate: first, study the effect of changing the reinforcement percentage by fibers on mechanical properties (Impact, tensile, and compressive strength) for composite material consist of Araldite resin reinforced by chopped glass fibers with density (2.6g/cm3) .glass fibers was mixed with araldite resin in different weight reinforcement percentage (20%, 40%, 60%) . the best results was obtained with large reinforcement percentage (60%). Second, study the effect ofthe same above reinforcement percentage on thermal conducting of composite material, where the result show increased thermal conducting with increasing percentage of reinforcement. Fourier equation was used to calculate the changing in thermal conductivity coefficient (k) for composite material.
