<p>A tool (100) for use in bonding a composite multi-layer shell (300) having complex curvature by the delta-alpha high temperature bonding process. The tool (100) includes a plurality of segments (110,120,130,140) that combine to form a mandrel assembly (100) having a substantially continuous outer surface (115). The outer surface (115) has a substantially axisymmetric shape including a complex curvature. When the segments (110,120,130,140) are combined to form the mandrel assembly (100), at least one of the segments (110,120,130,140) is configured to be movable in a substantially inward direction without substantial obstruction by any other segment (110,120,130,140). The segments (110,120,130,140) are constructed of a first material have a first coefficient of thermal expansion that is greater than a second coefficient of thermal expansion of a second material of a composite multi-layer shell (300) to be bonded together using the tool (100).</p> |
