Efficient Material Hybridization by Unconventional Layup and Forming of Metals and Composites for Fabrication of Multifunctional Structures (2017-2022)

Abstract

In the present work, ribbed beams have been manufactured by forging fiberglassreinforced polyamide using two different temperatures. The higher processing temperature studied (300 ºC) ensures the filling of the mold in the forging/GMT process, but also increases the fiber-matrix separation phenomenon, limiting the length of the rib with fiber (11%). This heterogeneity in the fiber content translates into a loss of stiffness and strength in the area of the rib with respect to the area of the base, of 70 and 60% respectively, for the most severe case (300 ºC). The second contribution of the work has been the demonstration of additive manufacturing, more specifically pellet extrusion, as a rapid prototyping technology in structural studies, since the stiffness of the 3D printing component was in intermediate values of the two forged prototypes, but its strength and elongation at break have been even higher.
