Today, there is a growing trend toward lighter constructions with excellent mechanical properties. For this reason, it is also necessary to produce a windsurfing board, which would be reinforced with aramid fibers to increase its resistance during falls on hard surfaces. However, this raised the question of how the combination of the aramid and carbon fibers would affect the stiffness of the windsurfing board and to what extent the aramid fibers would contribute to the impact resistance. To solve this problem, two types of tests were performed, a bending test and an impact test, on which four different samples were examined. Most of the samples were prepared in combination with carbon fibers and aramid fibers in a polymer binder. The results showed that the use of aramid fibers reduces the stiffness of the board. Moreover, at selected composite thicknesses, the aramid fibers do contribute to impact toughness.
