Lightweight structural materials with high strength and toughness are highly desirable for many advanced applications.Wood, as a sustainable structural material, is widely used in engineering due to its abundance and excellent mechanical properties.In this paper, we report a self-densification Insect Viewer strategy to develop super-strong wood by reassembling highly aligned wood fibers as functional units and self-densified without the need for hot pressing.

The resulting self-densified wood exhibits ultra-high tensile strength (496.1 MPa), flexural strength (392.7 MPa) and impact toughness (75.

2 kJ/m2), surpassing those of compressed densified wood and traditional metal materials like aluminum alloys.Notably, the self-densified wood exhibits uniform shrinkage in the cross-section while maintaining its longitudinal dimension.This characteristic leads to an order-of-magnitude enhancement in the overall mechanical performance of the Dice Accessories wood, presenting a significant advantage over compressed densified wood.

Such super-strong yet lightweight wood has great potential for application as a sustainable engineering material, replacing traditional structural materials such as metals and alloys.
