Abstract

See full text

Into a material based on a caoutchouc-type or caoutchouc-containing mixture for producing hard rubber, there is incorporated a pre-mix containing high-strength organic fibers and a liquid hardenable plastic material. The high-strength and temperature resistant material thus obtained is particularly suitable for the attenuation of noise in combustion engines when heavy-weight fillers are also added to such material. Engine components like, for example, valve covers, timing gear covers and oil pans can be manufactured from this material.
