Corrugated Core Made by 4D Printing of Composites for Flexible Aircraft Wing

Abstract

This paper presents a procedure to make composite corrugated core without the need for a mold with corrugated shape. The technique is called 4D printing of composites. The corrugated composite is intended to serve as the core for flexible aircraft wings. A demonstrator sample was manufactured and tested. It was shown that the flexible wing can morph up to 20o and can withstand loads for small unmanned arial vehicles.
