The polymerization of resin monomers was initiated in the presence of nanofibers as structural templates to prepare a hydrogel with nanofibrous networks, followed by the drying and pyrolysis to get hard carbon aerogel. During polymerization, the monomers deposit on templates and weld the fiber-fiber joints, leaving a random network structure with massive robust joints. Moreover, physical properties (such as diameters of nanofiber, densities of aerogels, and mechanical properties) can be controlled by simply tuning templates and the amount of raw materials.

The lightweight nature of FRP rectangular tubes is a significant advantage, particularly in situations where weight constraints are critical, such as in aerospace or automotive industries. They can be easily handled and installed, reducing labor costs and improving efficiency on job sites. Moreover, their resistance to corrosion and chemicals makes them suitable for applications in harsh environments, like chemical plants or offshore structures.
