Fiber reinforced ceramic matrix composite internal combustion engine exhaust manifold |
摘要 |
This invention discloses an exhaust manifold for an engine made of all fiber reinforced ceramic matrix composite material so as to be light weight and high temperature resistant. A method of making the exhaust manifold comprises the steps of forming a liner of a cast monolithic ceramic material containing pores, filling the pores of the cast monolithic ceramic material with a pre-ceramic polymer resin, coating reinforcing fibers with an interface material to prevent a pre-ceramic polymer resin from adhering strongly to the reinforcing fibers, forming a mixture of a pre-ceramic polymer resin and reinforcing fibers coated with the interface material, forming an exhaust manifold shaped structure from the mixture of the pre-ceramic polymer resin and the reinforcing fibers coated with the interface material by placing the mixture on at least a portion of the cast monolithic ceramic material, and firing the exhaust component shaped structure at a temperature and a time sufficient to convert the pre-ceramic polymer resin to a ceramic thereby forming a reinforced ceramic composite.
