Natural fibre-reinforced sandwich structural panels for building applications

该项目的目标是在工业规模上，使用一步成型程序，生产三层夹心板，由两层复合材料制成，由木材聚合物复合材料（WPC）和由结构聚合物泡沫（SPF）制成的低密度核心组成，有和没有木材添加。由于泡沫核心（增加弯曲刚度和冲击强度）以及由于蜂窝结构提供隔热和隔音，这些面板将重量轻且多功能。总体而言，将研究四个重要方面：1)生产和表征机械和热对称和非对称面板；2)开发对称和非对称面板的机械和热性能预测模型；3)优化与对称和非对称面板性能相关的加工条件；4)研究所有生产的面板的回收和长期性能的影响。该项目将为开发具有优异热学和结构性能的新型环保结构夹层材料提供知识和技术。该项目开发的新产品将应用于住宅和工业建筑的承重墙和屋顶板。

The objective of this project is to produce, on an industrial scale and using a single step molding procedure, three layers sandwich panels composed two composite skins made from wood polymer composites (WPC) and a low density core made of a structural polymer foam (SPF) with and without wood addition. These panels will be light weight and multi-functional due to the foamed core (increased flexural rigidity and impact strength) as well as providing thermal and acoustic insulation due to the cellular structure. Overall, four important aspects will be investigated: 1) to produce and characterize mechanically and thermally symmetric and asymmetric panels, 2) to develop predictive models for the mechanical and thermal properties of symmetric and asymmetric panels, 3)to optimize the processing conditions relating morphology to properties of symmetric and asymmetric panels, and 4) to study the effect of recycling and long term properties of all the panels produced. The project will deliver knowledge and technology for the development of new environmentally responsible structural sandwich materials with excellent thermal and structural properties. The new products developed in this project will have applications in residential and industrial buildings for load bearing walls and roof panels.
