Lightweight carbon-bonded carbon fiber composites prepared by pressure filtration technique

摘要: Abstract Carbon-bonded carbon fiber composites were produced by a simple pressure filtration technique. This method consists of dispersing fibers and phenolic resin to make slurry then pressing the water out through filter cloth, finally carbonizing at 1000 °C in nitrogen. A homogeneous microstructure without agglomeration layering was achieved. The compressive strength ranged from 0.2 1.1 MPa for different densities. thermal conductivity 0.23 g cm −3 0.2–0.43 0.11–0.35 W m −1  K directions perpendicular parallel pressure, respectively, 25–1300 °C.
