DEVELOPMENT OF ADVANCED ENERGY ABSORPTION SYSTEM USING NANOPOROUS MATERIALS
| Title: | DEVELOPMENT OF ADVANCED ENERGY ABSORPTION SYSTEM USING NANOPOROUS MATERIALS |
| Author: | Surani, Falgun |
| Description: | In a recent study, we have performed first-order analysis and proof-of-concept experiments for a novel application of nanoporous materials in developing high-performance pressure controllable nanoporous energy absorption system. When nanoporous particles are immersed in a non-wetting liquid, the liquid cannot enter the nanopores spontaneously. With the increase in external pressure, however, as the capillary effect is overcome, the liquid can be forced to infiltrate into the nanoporous material. Because of the factors that are still under investigation, as the pressure is reduced, in a certain types of nanoporous materials the confined liquid would remain in the nominally energetically unfavorable nanopores, and thus the excess solid-liquid interfacial energy can be considered as being "absorbed". Due to the large specific surface area (100-1000 m2/gm), the energy absorption effectiveness of this system can be in the range of 10-100 J/g. We experimentally demonstrated full control on system parameters like infiltration pressure (pin), recoverability and accessible infiltration pore volume (Vp) using admixtures and promoters. And we have successfully developed a solid like composite nanoporous energy absorption system which can largely simplify the design of protection devices and mechanical dampers. |
