The study of hybrid composites has been increasing for several types of applications aimed at combining the properties of these materials and obtaining new outcomes. In the present article, low-velocity impacts were conducted in an intraply/yarn hybrid composite (hybridization in the yarn of the fabric) in order to assess its residual mechanical properties and relate them to damage propagation, comparing the results with other materials in the literature and determining the extent to which this type of hybridization influences the final result. Thus, we developed a composite with 11 layers consisting of 3 layers of bidirectional intraply/yarn Kevlar/glass hybrid fabric for the middle and outer layers of the laminate and 8 layers of bidirectional glass fiber fabric. The tests were conducted using two impact energies (61 and 76 J) until total penetration. The impact resistance of the hybrid yarn fabric improved, exhibiting a decline in the damage area, with low delamination and the possibility of repair. [ABSTRACT FROM AUTHOR] |
