which would be a great benefit as compared to fixed-wing aircraft," Hoa explains. He believes the composite 4D technology has great potential for all manner of applications. Its products ...

Using a technique Hoa pioneered known as 4D printing of composites, the authors performed a feasibility study on the application of a new way to manufacture adaptive compliant trailing edge (ACTE) ...

This innovation, inspired by the hierarchical structure of butterfly wings, holds significant promise ... This streamlined 4D printing approach marks a significant advance in micro/nanoscale ...

After being lifted straight up a 120-foot hill, this 4D Wing Coaster challenges riders to "face their fears" as they flip head-over-heels at least six times along the weightless, tumbling journey.

“Our paper shows that a UAV using this kind of wing can support a good amount of load for small or medium-sized vehicles,” says Hoa, director of the Concordia Centre for Composites. 4D ...

In a new paper published in the journal Composite Structures ("Development of a new flexible wing concept for Unmanned Aerial Vehicle using corrugated core made by 4D printing of composites"), Suong ...
