The invention relates to a material consisting of several layers for protecting parts of the body against penetrating objects, such as shells or splinters for instance. The inventive material comprises at least one energy- distributing layer (2) and at least one energy-receiving layer (3) as well as a protection insole (1) for shoes, a protection shoe (8) and protection outer wear using such a material consisting of several layers. The aim of the invention is to produce such a material by means of which good protective effects and high elasticity can be obtained. According to the invention, the energy-receiving protective layer (3) which is arranged behind an energy- distributing layer (2) when seen in the direction of impact of the object consists of a three-dimensional matrix on the basis of polynorbornenes.
L'invention concerne un matériau multicouche destiné à protéger des parties du corps contre des objets pénétrants tels que des projectiles ou des éclats, ledit matériau étant composé d'au moins une couche (2) de répartition de l'énergie, et d'au moins une couche d'absorption de l'énergie (3). L'invention concerne également une doublure de protection (1) pour chaussures, une chaussure de protection (8) et un vêtement de protection faisant intervenir un tel matériau multicouche. L'invention vise à mettre en oeuvre un tel matériau garantissant en même temps une protection et une élasticité élevées. A cet effet, la couche de protection (3) absorbant l'énergie, disposée derrière une couche (2) de répartition de l'énergie dans le sens d'impact de l'objet, est composée d'une matrice tridimensionnelle à base de polynorbones.
