Abstract
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.
Claims9
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 structural members are configured to correspond to the predetermined configuration of the structural assembly.
