A preform and method for forming a structural assembly are provided. The preform can be formed by friction welding structural members to a base member and subsequently providing a connection material to join the structural members. The resulting preform can be formed with dimensions and a configuration that approximate the dimensions and configuration of the structural assembly. Thus, the structural assembly can be formed by joining multiple members that are generally smaller than the finished assembly.

That which is claimed: 1. A preform for forming a structural assembly having a predetermined configuration, the preform comprising: a base member; a plurality of elongate structural members, each structural member defining first and second distal ends and at least one side extending therebetween, the first end of each structural member being joined by a friction weld joint to the base member, and the sides of the structural members defining spaces therebetween; and a connection material disposed in the spaces, the connection material being frictionally welded to the structural members adjacent each space such that the connection material in each space connects at least two of the structural members; at least one retainer member adjacent each respective space such that the at least one retainer member and the structural members adjacent the respective space substantially define a closed circumference extending around the space, wherein the structural members are configured to correspond to the predetermined configuration of the structural assembly. 2. A preform according to claim 1 wherein each of the friction weld joints connecting the structural members to the base member is at least one of the group consisting of rotary friction weld joints and linear friction weld joints. 3. A preform according to claim 1 wherein the connection material disposed in each respective space comprises a hydro pillar weld joint joining the structural members adjacent the respective space. 4. A preform according to claim 1 wherein the connection material is structured as a plurality of connection members, each connection member having a generally circular cross-sectional shape. 5. A preform according to claim 1 further comprising at least one friction stir weld joint extending at least partially through the connection material and joining the connection material to at least one of the base member and the structural members adjacent the connection material. 6. A preform according to claim 1 further comprising at least three structural members friction welded to the base member, the three structural members being configured to correspond to the predetermined configuration of the structural assembly and defining spaces therebetween. 7. A preform according to claim 1 wherein the structural members are connected to the base member such that longitudinal axes of the structural members are configured in a substantially parallel configuration. 8. A preform according to claim 1 wherein each of the base member, the structural members, and the connection material is formed of at least one of the group consisting of aluminum, aluminum alloys, titanium, titanium alloys, steel, nickel-based alloys, copper-based alloys, and beryllium-based alloys. 9. A preform for forming a structural assembly having a predetermined configuration, the preform comprising: a base member; a plurality of elongate structural members, each structural member defining first and second distal ends and at least one side extending therebetween, the first end of each structural member being joined by a friction weld joint to the base member, and the sides of the structural members defining spaces therebetween; and a connection material disposed in the spaces, the connection material being frictionally welded to the structural members adjacent each space such that the connection material in each space connects at least two of the structural members, wherein the friction weld joints connecting the structural members to the base members are a different type of weld joint than the connection material disposed in the spaces, and wherein the structural members are configured to correspond to the predetermined configuration of the structural assembly. 10. A preform according to claim 9 wherein each of the friction weld joints connecting the structural members to the base member is at least one of the group consisting of rotary friction weld joints and linear friction weld joints. 11. A preform according to claim 9 wherein the connection material disposed in each respective space comprises a hydro pillar weld joint joining the structural members adjacent the respective space. 12. A preform according to claim 9 wherein the connection material is structured as a plurality of connection members, each connection member having a generally circular cross-sectional shape. 13. A preform according to claim 9 further comprising at least one retainer member adjacent each respective space such that the at least one retainer member and the structural members adjacent the respective space substantially define a closed circumference extending around the space. 14. A preform according to claim 9 further comprising at least three structural members friction welded to the base member, the three structural members being configured to correspond to the predetermined configuration of the structural assembly and defining spaces therebetween. 15. A preform according to claim 9 wherein the structural members are connected to the base member such that longitudinal axes of the structural members are configured in a substantially parallel configuration. 16. A preform according to claim 9 wherein each of the base member, the structural members, and the connection material is formed of at least one of the group consisting of aluminum, aluminum alloys, titanium, titanium alloys, steel, nickel-based alloys, copper-based alloys, and beryllium-based alloys.
