Morgan Advanced Materials announces brazed carbon fiber‒titanium honeycomb capability

News International-French

30 Oct 2014

The company announces the development of a new capability of brazing carbon fiber, ceramics, composites, or other engineered materials directly to a titanium honeycomb. This technique brings together qualities of both components, ensuring a final material that is strong, lightweight, and impact- and heat-resistant.

Carbon fiber and other similar non-metallic engineered materials have exceptional thermal conductivity capabilities, and are able to remain strong at temperatures exceeding 2000°F, far higher than those at which any metals retain their strength. Titanium honeycomb adds greater strength to the carbon fiber and eliminates fracturing issues by transferring forces from impact better than the carbon fiber alone. Both materials are exceedingly lightweight.

In addition, the strength of the braze bond is exceptional, equaling or exceeding the strength of each component material, unlike the reduced strength of adhesive, riveted, or other bonds. The addition of the titanium honeycomb to the carbon fiber allows easy joining of the titanium to other structures through traditional joining techniques.

This material is good for aerospace applications, especially on lifting surfaces such as wings or flaps, where strength, low weight and a thin cross-section are important, and the rear sections of engines, where combined high strength and thermal transfer is important. The material has the capability for use in hypersonic crafts, given that such high speeds require great strength and often lead to exceptionally high temperatures on leading edges.

Beyond aerospace applications, engineers from Morgan expect that this new material will be useful wherever light weight, extremely high strength and exceptional thermal capabilities are mission-critical, such as in certain automotive or defense applications.
