    Given the problem of finding an alternative composite material for application in the manufacture and repair of aircraft flight surfaces of the CID-FAE, there is a need to venture into a new material with more optimal mechanical properties for aircraft. For this, 22 case studies were elaborated with several combinations of fibers like glass, aramid, carbon and copper with different number of layers (7, 8 or 9) and different orientation of the same (0, 45 or 135 degrees). In the test tube’s made in vacuum were carried out tensile, bending and impact tests under ASTM D3039, ASTM D7276 and ASTM D5628-10 standards respectively. Obtaining the data of mechanical´s properties of the study cases, we proceeded to carry out design of experiments using a DCA Design completely at random since it was the most optimal for the case study with an input factor of the number of layers and their orientation and levels (7, 8 and 9) and (0, 45 or 135 degrees) respectively. Determining that the essay of test tube with best performance and mechanical properties was the so-called S composed of 6 carbon fibers at 0 degrees, 1 at 135 degrees and 1 copper fiber at 0 degrees, being the essay suggested for use in aircrafts since it has a Force at the traction of 639.57 MPa, Bending stress of 453.94 MPa and Impact energy of 3.39 J.
