Forming Process and Simulation Analysis of Helical Carbon Fiber Reinforced Aluminum Matrix Composite

Abstract

In order to promote the industrialization of the large deformation technology of carbon fiber composites, this paper studies a new method of forming of helical carbon fiber reinforced aluminum matrix composite. The purpose is to solve the problem of large deformation of carbon fiber with low elongation and metal matrix with high elongation. By introducing carbon fiber with helical space structure into the aluminum matrix, the helical carbon fiber reinforced aluminum matrix composites were prepared and the subsequent drawing deformation was carried out. Here we systematically studied the large plastic deformation behavior of helical carbon fiber reinforced aluminum matrix composite via a combination of numerical simulations and experiments, and analyzed the deformation law and stress of helical carbon fiber in the deformation process. We found that the plastic deformation of the composite causes local stress concentration around the helical carbon fiber, and the helical carbon fiber will move synchronously with the aluminum matrix during the deformation, and receive the pressure from the aluminum matrix. Second, the best process parameters obtained from the simulation, that is, the drawing die angle α = 7°, when five-pass drawing experiments were carried out, the total deformation reached 58%, and the average elongation of a single pass was 18.9%. The experimental show carbon fiber reinforced aluminum matrix composite with helical space structure can achieve large deformation and high strength. The experimental and simulation are in general agreement, which verifies the correctness of the carbon fiber helical structure model.

Continuous Casting Preparation Process of Helical Fiber Reinforced Metal Matrix Composites

“…Whether winding the carbon fiber on a metal rod or fixing the carbon fiber in the helical shape with a high melting point metal wire, to prepare the helical carbon fiber reinforced metal composites. Liang [27] et al proved that the helical carbon fiber can deform with the deformation of the matrix through simulation and drawing experiments. However, the helical carbon fiber reinforced aluminum matrix composite is prepared by winding carbon fiber on the central aluminum rod and casting a layer of aluminum on the outer layer.…”

Study on Mechanical Properties and Microstructure of FeCoCrNi/Al Composites via Cryorolling

“…Aluminum matrix composites (AMCs) have many advantages, such as high specific strength and good wear resistance, that have attracted them more attention in recent years [1][2][3][4]. According to the reinforcement shape, AMCs mainly include continuous-fiber, whisker, and particle-reinforced composites [5][6][7]. Particle-reinforced aluminum matrix composites have become the most widely studied AMCs because of the advantages of the simple preparation process and low manufacturing cost [8][9][10].…”
