COMPOSITE PANEL MADE OF MULTIWALL POLYCARBONATE SHEET COVERED BY LAMINATE LAYER

A structural type panel (10) is described， particularly suitable for the production of furnishings and fittings for interiors and exteriors， for vehicles used in the terrestrial， maritime and aerospace sector， but also for the construction of artifacts， walls and structures. The panel (10) comprises a pair of laminated-sheet surfaces (12， 14)， which are substantially flat， opposing and parallel and furthermore form the outer longitudinal walls of the panel (10)， and at least one multiwall-polycarbonate reinforcement structure (16)， which is enclosed between the two surfaces (12， 14) and is provided with a plurality of internal walls (18) which define a plurality of respective channels or cells (20) with longitudinal extension. The internal walls (18) and the respective channels or cells (20) are respectively oriented longitudinally and along a parallel direction to the development planes of the two surfaces (12， 14)， such that at least a longitudinal portion of one or more walls internal (18) is arranged in contact with at least one of the two surfaces (12， 14). Each of the two surfaces (12， 14) is coupled to the multiwall reinforcing structure (1 6) by a bonding layer (22) which is deposited between the multiwall reinforcing structure (16) and the fixing side of each of the two surfaces (12， 14). The bonding layer (22) substantially extends throughout the whole area of each of the two surfaces (12， 14).

本发明公开了一种结构型面板（structural type panel）10，其尤其适用于制作室内外装饰家具与配件、陆地、海事及航空航天领域所用车辆的内外装构件，亦可用于建造人造构件、墙体及各类结构体。该面板10包含一对大体平坦、相对且平行的层压板材表面（laminated-sheet surfaces）12、14，二者同时构成面板10的外部纵向壁面；还包含至少一个封装于两表面12、14之间的多壁聚碳酸酯增强结构（multiwall-polycarbonate reinforcement structure）16，该结构设有多根内壁（internal walls）18，这些内壁界定出多个沿纵向延伸的对应槽道或胞腔（channels or cells）20。内壁18与对应的槽道或胞腔20分别沿纵向及与两表面12、14延展平面平行的方向定向，使得一根或多根内壁18的至少一段纵向部分与两表面12、14中的至少一者贴合接触。两表面12、14各自通过粘结层（bonding layer）22与多壁增强结构（multiwall reinforcing structure）16相连，该粘结层沉积于多壁增强结构16与两表面12、14各自的固定侧之间，且粘结层22基本覆盖两表面12、14各自的全部区域。
