Finally, the supply chain disruptions caused by the COVID-19 pandemic have also contributed to the price increase of the Jack Hammer. Factories that produce power tools may have been forced to shut down or operate at reduced capacity due to lockdowns and other restrictions. This has led to a decrease in the supply of Jack Hammers, which in turn has driven up prices as consumers compete for a limited number of available units.

FRP, a composite material composed of glass fibers embedded in a polymer matrix, boasts an array of advantageous properties. Its lightweight nature makes it easier to transport and install, reducing overall construction time and labor costs. Despite its lightness, FRP possesses exceptional strength and durability, capable of withstanding harsh weather conditions, corrosion, and even seismic activities, making it ideal for regions prone to natural disasters.

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.
