Preparation and Mechanical Properties of Continuous Carbon Nanotube Networks Modified Cf/SiC Composite

Preparation and Mechanical Properties of Continuous Carbon Nanotube Networks Modified Cf/SiC Composite

Continuous carbon nanotube (CNT) networks were formed in Cf/SiC composites via freeze-drying method. Composites were fabricated by precursor infiltration and pyrolysis (PIP) process afterwards. The different distribution morphologies of CNTs in the preforms originating from the different CNT content...
