For over 40 years, Aeronca has produced several thousand pieces of brazed hardware. Aeronca developed high temperature brazing technologies for couple structures. These structures have proven ideal for many aerospace applications, particularly those in which a high temperature, high strength-to-weight ratio is a requirement. Brazed structures have high energy-absorption capability and are ideally suited for environments where difficult combinations of aerodynamic, acoustic, and thermal loads exist. Weld/brazing technology offers greater design flexibility than conventional resistance and fusion welding. Aeronca manufacturing processes allow the brazing of very thin materials, as well as brazing of thin-to-thick materials. This process is applicable to the joining of multiple sheets and dissimilar materials. Brazed structures offer excellent strength and fatigue resistance. Details are tack-welded or
spot-welded together and then brazed. This
self-fixturing technique eliminates the need for costly tooling normally required in more conventional joining methods.

Utilizing it's in-house metallic honeycomb manufacturing capability, Aeronca produces brazed honeycomb components from stainless steel and titanium alloys as well as nickel-based super alloys. Structures and parts can be made in various configurations, sizes, and shapes -- including conical, cylindrical, curved, flat, and wedged. Variation in face sheet thickness, core thickness, core density, fittings, edge members and configuration of internal structures can be tailored to the design requirements. This technology allows excellent design flexibility. The weight and strength requirements can be exactly tailored to the customer's needs.

Honeycomb sandwich construction offers the ultimate in lightweight, high-strength structures. The core prevents unstable buckling of sandwich facing and provides a direct shear transfer path to edge members and fittings. Sound attenuation treatment can be readily incorporated.

Aeronca maintains an ongoing research and development program to expand brazing technology and to improve brazed material systems and the technique of repairing brazed structures. Aluminum brazed titanium was developed under an Aeronca/Boeing R and D project.
