Boron nitride-strengthened polymer matrix composites based on 3-dimensional porous materials are a considerable problem to develop. GO-BN aerogel (GO-BN) has been generated using a unique method for manufacturing large-scale 3D BNs and graphene oxide (GO) aerogels. Propylene was then added to the aerogel and polymerized in situ to create GO-BN/PP nanocomposites. Afterwards, the outcomes show that BNs and GO-BN were successfully established and that the 3D outlines using GO-BN aerogel have outstanding mechanical properties. Around 1% of the nanocomposite was used in its construction. This aerogel's thermal conductivity was 0.135 W/mK, and its mechanical properties were greatly improved over those of pristine PP, with increases of 10.12 percent in tensile strength and 48.4 percent in flexural strength and 61.5 percent in compression strength. They may now be produced in big quantities using this simple preparation procedure.
