ABSTRACT:
The structural assemblies are selectively reinforced with metal matrix composite in the regions susceptible to mechanical failure. More specifically, a channel is machined in a structural member in an area of relatively high stress. A reinforcing member is inserted into the channel. A metal powder is deposited on and around the reinforcing member. The metal powder is irradiated by a high energy source to thereby encase the reinforcing member in a metal matrix and to consolidate the metal matrix to the interior surface of the channel. The resultant assembly is lightweight and has improved strength and stiffness at room and elevated temperatures.
