The invention relates to a multiple-layer composite board of discrete materials and plastic. The multiple-layer composite board of discrete materials and plastic is formed by providing independently stratified plastic layers and discrete material layers, which are pressed in melting state of the alternate plastic layers and discrete material layers and cooled. Due to this stratification, centralized plastic layers constitute high load capacity and discrete material layers pressed with pressure lower than normal extrusion process constitute low density for the multiple-layer composite board of discrete materials and plastic. L'invention concerne un panneau composite multicouche constitué de matériaux discrets et de plastique. Le panneau composite multicouche constitué de matériaux discrets et de plastique est formé en fournissant des couches de plastique stratifiées indépendamment et des couches de matériaux discrets, qui sont pressées dans l'état de fusion des couches de plastique alternées et des couches de matériaux discrets, puis refroidies. Grâce à la présente stratification, des couches de plastique centralisées constituent une capacité de charge élevée et des couches de matériaux discrets pressées avec une pression inférieure au procédé d'extrusion normal constituent une faible densité pour le panneau composite multicouche de matériaux discrets et de plastique.
