Abstract:
The ballistic performance of epoxy matrix composites reinforced with 10, 20 and 30% by volume of babassu fibers was investigated for the first time. The tests carried out included Izod impact tests and ballistic tests with 0.22 caliber ammunition. The Izod impact tests showed significant improvements with increasing babassu fiber content, indicating greater strength of the composites. Scanning electron microscopy analysis revealed the fracture modes of the composites, highlighting brittle fractures in the epoxy matrix, as well as other mechanisms such as fiber breakage and delamination in the fiber-reinforced composites. In the ballistic tests, a significant increase in the energy absorbed by the composites was observed. All composites outperformed pure epoxy by more than 3.5 times in ballistic energy absorption, highlighting the potential of babassu fibers for engineering and defense applications. These results indicate that babassu fibers can be an effective and sustainable alternative for improving the performance of composite materials.
