Deformation Behavior of Carbon Fiber/Al Composites with Corrugated Structure for Developing the Rolling Plate

Abstract

Herein, a rolling strategy for carbon fiber (CF)/Al composites is proposed, that is, by constructing a corrugated structure of Sn‐protected CFs ([CF@Sn]≈Al composites), to realize the cooperative extension of woven CFs with Al matrix deformation in the rolling process. The matching extension feasibility and structural optimization of (CF@Sn]≈Al composites are calculated based on the designed 3D numerical model of rolling system. The [CF@Sn]≈Al composites have successfully combined excellent mechanical properties while meeting the extension design of the CF reinforcement. Mechanical testing of the samples indicates that the tensile strength of the [CF@Sn]≈Al composites increases by 18.6% while the bending strength is more than 23.2% higher than that of the rolled Al matrix. The present work provides an effective method for developing the deformed CF/Al composites as rolling plate in lightweight applications.
