Abstract
The invention refers to an elastic body by synthetic material or rubber which is equipped with tube like hollow spaces in which capsules, containing a foam creating liquid, are arranged. At an explosion or other outer pressure influence the capsules will break and the liquid (foam) will fill up the hollow spaces and will get stiff to an elastic foam. The invention can be used for example manufacturing of tires.
Claims2
An elastic body consisting of rubber or synthetic material with an arbitrary shape essentially keeping its elastic qualities after being damaged by a blow, hits, cracking or external pressure change, said elastic body containing a plurality of hollow spacings in the form of tubes extending in random directions throughout the body, said tubes being uniformly distributed inside the body and having an arbitrary crosssection essentially smaller than an overall dimension of the body, at least some of said tubes including organ means for enclosing a foamable a liquid medium wherein at a sudden pressure change said organ means breaks and said foamable liquid medium expands to a foam which rapidly congeals filling its associated surrounding tube and a possible empty space created by said damage of the elastic body.
