Carbon foams: Engineered carbon foams are lightweight, high-temperature materials with tailorable strength and resistance to fire and chemicals

摘要

Carbon and graphite foams offer properties such as chemical inertness, ultra high service temperatures, low coefficient of thermal ex-pansion, and tailorable electrical/thermal conductivity. Carbon foams generally fall into two categories - graphitic and non-graphitic. The graphitic carbon foams offer high thermal and electrical conductivity, but considerably lower mechanical strength than the non-graphitic foams. Non-graphitic carbon foams are generally stronger, act as thermal insulators, and cost far less to manufacture.
