The simplest and most common form of textile reinforcement for composites are fabrics. The bidirectional structure, when submitted to a mechanical stress, deforms in the wicks, causing them to have a less effective length. One of the ways to achieve an increase in interlaminar fracture toughness is to make the surface of the fabric have an inherent surface roughness. The positioning of fibers in multiple directions allows an increase in fracture toughness due to the blockage of crack propagation and also due to other processes that consume energy during the fracture. In this article the mechanical behavior of the epoxy composite reinforced with 40 vol% of hybrid fabric composed of Mallow and Juta, in a multidirectional configuration of the layers [0/90/-45/+45], was evaluated. The results obtained were very expressive, demonstrating its great potential in ballistic application.
