Adhesive Bonding of Composite Metal Parts Using Conformal Wall

The patent applies homogeneity by ensuring constant adhesive layer thickness throughout the bonding process. The wall is designed with an internal face that has the same shape as the part to be bonded, which maintains a uniform adhesive layer thickness regardless of the complex external geometry of the parts. This resolves the contradiction by achieving both manufacturability of complex shapes and satisfactory mechanical properties through homogeneous adhesive distribution.

The patent employs a wall with an internal face shaped to match the part geometry, which acts as a flexible conforming surface. This wall can adapt to complex three-dimensional shapes while maintaining constant pressure on the adhesive layer. The wall's ability to conform to the part shape allows uniform pressure distribution without requiring complex pressure application devices, thus improving bonding quality while managing device complexity.

The patent applies the copying principle by creating a wall whose internal face is shaped to match the external shape of the part to be bonded. This copy of the part geometry allows the wall to conform perfectly to the part surface, ensuring uniform pressure distribution on the adhesive layer. While this does increase wall design complexity, it provides a systematic and reusable solution that simplifies the overall bonding process for complex shapes.

The patent makes the wall multi-functional by having it serve both as a pressure application surface and as a thermal management interface. The wall's internal face, shaped to match the part geometry, provides uniform contact for both pressure and heat transfer. This universal interface simplifies temperature control by ensuring uniform thermal contact across the entire bonding surface, improving bonding quality without requiring separate complex temperature control systems.
