Tensile mechanical behavior of a polymeric composite reinforced with 4-axial carbon fiber woven

摘要

During the last thirty years, there has been a growth in the study and analysis of composite materials for automotive and aerospace industry which require lightweight materials with demanding mechanical properties. textile reinforce composite materials have advantages with respect to laminated composite materials such as better formability and out-of-plane properties. Therefore, the purpose of this research is to determine the mechanical behavior for uniaxial testing of a carbon fiber of a composite material reinforced with a quadriaxial carbon fiber woven in order to decrease the anisotropy of the woven composite material. Five specimens for each of the different orientations at 0, 30, 45, and 90 degrees; In addition, six specimens of a plain woven (the most common on the market) were tested, two specimens per orientation at 0, 45 and 90 degrees, in order to contrast the behavior of these with the proposed tissue. It was obtained that the properties in the composite materials change according to the direction in which the fibers are oriented; therefore, the results showed that the quadriaxial tissue and the stress value are less than the plain tissue, by 39%, only in the zero degrees orientation, then the plaint woven has a greater number of fibers in that orientation, the orientation of ninety degrees is higher by 17%, and in the case of forty-five degrees orientation, the value is 82% higher. In the same way, when we study the orientations in there is no fiber, in the plain woven of the direction in which there is no fiber, is forty-five degrees' orientation and in the proposed tissue it is the thirty-degree one 30 degrees and it can be seen that, in this case, in the behavior of the quadriaxial tissue is greater the stress value by 66%.
