The application provides a space on-
orbit flexible
sealant nail integrated self-sensing pressure sealing patch, which adopts a form of a
sealant patch, and designs a stepped
sealant nail integrated
layered structure, which comprises a stepped flexible sealant nail integrated support layer, a flexible sealant body sealing and bonding layer, a
metal protective backing, an aluminized film packaging bag, a
silicon-based release paper, a ring-shaped film piezoresistive
pressure sensor, a
direct current ultra-fine heating wire, a micro 6-pin rectangular electric connector female head, a temperature measuring sensor PT100 and a portable sensing and
processing module. By using the scheme, the problems that the existing leak sealing and repairing technologies cannot accurately and completely seal unknown shape leak holes, have poor
space environment adaptability, cannot bear pressure and have poor anti-splitting performance and the like can be solved, and a better leak sealing effect is achieved.
