Abstract
This invention generally pertains to self propagating high temperature synthesis or combustion synthesis as a way of bonding materials. The present invention provides methods and an apparatus for bonding, preferably carbon-carbon composite materials, by combustion synthesis. Generally, the invention involves providing at least two carbon-carbon composite parts to be bonded and interspersing a combustion synthesis material in between the parts with each part in contact with the combustion synthesis material. The combustion synthesis material is then ignited, which initiates the combustion synthesis reaction. Typically, a ceramic material is formed which immediately freezes, bonding the parts together.
