Abstract
In this paper, a novel 3D printed continuous ramie fiber reinforced variable stiffness biocomposite honeycomb cellular structure (CF-VSHS) was reported. Based on the printing path planning of CF-VSHSs, variable stiffness (VS) cellular structures filled with cells of various dimensions were prepared by employing a detachable and recyclable support-assisted printing method. In order to evaluate the mechanical performances of CF-VSHSs, compressive tests were conducted. The results showed that CF-VSHSs effectively filled the performance gap area of the cellular structures. The energy absorption (EA), initial peak force (IPF), stiffness (S), and other performance indicators of CF-VSHSs were all located between the performance of different cellular structures. In addition, 3D printed CF-VSHSs were analyzed regarding failure processes and damage features to reveal their structure-compressive performance relationship.
