Patent

CA 2258255

The invention relates to a structural member and a process for producing a structural member with at least one layer (13, 18, 19) of plastic and with a layer (14, 15) inside the structural member (11) of a material which has a substantially higher modulus of elasticity than plastic. Said member also has at least one system plane (12) which is part of the structural member (11) and along which the structural member (11) has substantially homogenous properties and a substantially homogenous structure. The invention is characterised in that along the system plane (12) at least one inner layer (13) and a respective outer layer (18) consisting of plastic are provided between which two layers each separated from each other and transversing the system plane (12) with the second higher modulus of elasticity are provided.

L'invention concerne un élément structural et un procédé pour produire un élément structural avec au moins une couche (13, 18, 19) de plastique et avec une couche (14, 15), située à l'intérieur de l'élément structural (11), en un matériau présentant un module d'élasticité sensiblement plus élevé que le plastique. Cet élément présente également au moins un plan système (12) qui fait partie de l'élément structural (11) et le long duquel cet élément structural (11) présente des caractéristiques sensiblement homogènes et une structure sensiblement homogène. L'invention est caractérisée en ce que le long de ce plan système (12) sont disposées au moins une couche intérieure (13) et une couche extérieure respective (18) en plastique, entre lesquelles sont disposées deux couches respectivement séparées l'une de l'autre, traversant le plan système (12) et présentant le deuxième module d'élasticité plus élevé.
