Polyether ether ketone and which combined with carbon fiber by 20% and 30% as reinforcement which purchased from a company Tangyin Sanyou Engineering Plastic Co. Itd/China. the degree of crystallization An significant role in semi-crystalline thermoplastics is played by (e.g. toughness, stiffness and solvent resistance). Primary aim of this work is to use density, DSC and FTIR to Research into the various induced degrees of crystallinity in PEEK composites Strengthened with carbon fiber (CF). In this research, three sheets were used: virgin poly ether ether ketone (PEEK), (PEEK+20 percent carbon fiber), and (PEEK+30 percent carbon fiber). the samples’ mechanical and thermal properties produced ones were examined and compared in this study. The density test findings displayed a rise in crystallinity levels by (35.9, 54.4, 88.2) respectively, But a decrease in the degree of crystallinity when examining by DSC. The mechanical properties such as Tensile strength, Young’s module and impact strength It showed an improvement in properties with an increase in the percentage of reinforcement with CF. In addition, FTIR for pure PEEK, (PEEK+ 20 percent CF) and (PEEK+30 percent CF) is found to induce minor shafting in peaks by adding 30 percent of carbon fibers and does not cause new peaks to appear and this suggests that there is no chemical reaction between the fibers and the PEEK matrix.
