- In the world of composite materials, FRP (Fiber-Reinforced Plastics) laundering is a specialized technique that involves cleaning and rejuvenating fiberglass-reinforced plastic surfaces. This process not only restores the aesthetic appeal of the material but also enhances its structural integrity and prolongs its lifespan.
- Next, the Ingersoll Rand 2115QXI is another top contender. This industrial-grade jack hammer is renowned for its robust design and consistent performance. With a powerful 1.5 HP motor, it can easily tackle the toughest concrete and masonry jobs. The inclusion of a QUIK-LOK™ chuck system allows for fast bit changes, saving precious time on the job site.


Due to the hard carbon nanofibers and abundant welded joints among the nanofibers, the hard carbon aerogels display robust and stable mechanical performances, including super-elasticity, high strength, extremely fast recovery speed (860 mm s-1) and low energy loss coefficient (<0.16). After tested under 50 % strain for 104 cycles, the carbon aerogel shows only 2 % plastic deformation, and retained 93 % original stress.
