Abstract

The study investigates the influence of incorporating carbon nanoparticles (CNP) and polypropylene fibers into epoxy composites on their mechanical properties, focusing on the elastic modulus and hardness. The results show that an increase in the weight percentage of polypropylene fibers leads to a corresponding rise in the elastic modulus of the epoxy composites. The presence of nanocarbon black (CNP) in various concentrations did not have a clear effect on the elastic modulus. On the other hand, the elastic modulus increased linearly with increasing the percentage of hybrid filler (CNP/PP). Regarding to hardness test that was achieved using the shore D tester, lubrication properties improved with increasing weight percentages of CNP, while the hardness decreased a lot with increasing the weight percentage of polypropylene fibers. the results of the recovery test revealed that the CNP plays a major role in a preference for healing along the width axis of the groove, while the addition of polypropylene fiber makes the epoxy matrix favor healing along the depth axis, When using hybrid filler (CNP/PP) the recovery behavior was almost equal in both the transverse and depth axes. The above results shed light on the recovery behavior of hybrid composites and the possibility of their self-healing while at the same time improving their mechanical properties and thus increasing the requirements they perform in various engineering applications.
