الملخص

The aim of this work is to study the effect of additives (fiber) on the crystallinity of Polyether ether ketone (PEEK), which is combined with carbon fiber as reinforcement, because the degree of crystallinity plays an important role in semi-crystalline thermoplastics (such as toughness, stiffness, and solvent resistance). Three sheets were used (pure PEEK, PEEK with 20% carbon fiber, and PEEK with 30% carbon fiber). One of the most important tests used in this work is the density test, X-ray test, DSC, and FTIR to investigate the different degrees of crystallization induced in PEEK composites reinforced with carbon fibers in different proportions. Density test results showed a rise in crystallization levels of (35.9%, 54.4%, 88.2%) respectively. X-Ray test results showed a rise in crystallization levels (61.9%, 76.8%, 90%) respectively. In FTIR test, it is found that the addition of 20% and 30% of carbon fibers causes a slight shift in peaks and does not result in the creation of new peaks. This indicates that the fibers and the PEEK matrix do not react chemically; only there is a physical reaction, and the presence of carbon fiber decreases the peak sharpness. In the mechanical properties, such as tensile strength, Young’s modulus, and impact strength, showed improvement in properties with an increase in reinforcement ratio with carbon fibers. But during the DSC examination, a decrease in crystallinity was observed when examined by DSC (41.42%, 21.83%, 19.47%) respectively. The degree of crystallinity decreased because the method of preparing the sample does not clearly show the effect of the fiber. The samples used in this test are small, fine particles, which means that the sample is closer to the pure sample than the reinforced sample. Also, the heat cycle is not ideal for the PEEK sample; it should be a complete heating and cooling cycle.
