Syntactic metal foam

from Wikipedia, the free encyclopedia

Syntactic metal foams are composite materials consisting of a matrix with inserted hollow elements. These are mostly hollow glass microspheres or hollow metallic or ceramic spheres.

properties

Compared to conventional metal foams, syntactic foams have a significantly higher compressive strength due to the inherent strength of inserted hollow elements. It is also characterized by its low density and high energy absorption capacity.

application

In the class of lightweight materials syntactic foams are widely used in a variety of technical applications, such as in the aviation and aerospace , maritime technology for deep-sea applications and the automotive industry used. Syntactic foams offer an application as an energy absorber or the use of acoustic material properties for, for example, ultrasonic coupling elements.
