An ultra-flexible hexagonal boron nitride (h-BN)/ polymethyl methacrylate (PMMA) composite with extra-large elongation at rupture was prepared by introducing micron-sized surface-modified h-BN platelets into a PMMA matrix. At 32wt% loading of surface-modified h-BN, the composite can be folded freely and has an elongation at rupture of 68%, which is over 30 times larger than that of PMMA. Such results...
The mechanical properties at ambient and high temperature of Al 4 SiC 4 bulk ceramics prepared by solid state reaction were investigated. By increasing the sintering temperature slightly, the room temperature bending strength increased up to 318MPa, whereas, the fracture toughness decreased with the increase of the sintering temperatures. The high temperature bending strengths of the...
