**7. Conclusions**

A comparative study of two arrangements tested at high velocity impact was carried out to highlight improvements conferred by a polypropylene matrix to aramid fibers. Two arrangements were made of plain woven aramid fibers/PP, with consolidated and independent configurations. As observed in this work, the presence of the PP matrix generated advantages, such as a reduction in trauma depth in both cases in comparison to the sample without the PP matrix, where the independent laminates presented more back deformation but higher energy absorption than the consolidated laminates. Another advantage that needs to be evaluated, is the protection the matrix confers to the aramid against humidity and substances that may degrade it, such as UV light, thereby extending its lifespan.
