Development and characterization of layered sandwich panel system with ceramic core

该项目将开发和表征一系列陶瓷复合材料，用于所研究的结构夹层板系统。 陶瓷复合材料是使用化学反应的镁/磷酸盐粘合剂系统与工业废灰和轻质膨胀粘土骨料组合形成的。 陶瓷复合材料的流变和机械性能将根据混凝土行业采用的标准化测试程序进行表征。将在混合比例、混合程序和获得的性能之间建立分析关系。 在项目的后期阶段，将开发由陶瓷复合材料和玻璃纤维增强织物交替层形成的结构板，并进行弯曲失效测试。 将研究面板组成和面板配置对结构性能的影响。 根据实测的各组成材料的力学性能，建立了能准确反映板的强度和刚度的分析模型。通过考虑在房屋建筑中作为目标应用的非结构定向刨花板或胶合板覆板的可能替代品，将开发大规模面板用于现场试验。

This project will develop and characterize a family of ceramic composites for use within the investigated structural sandwich panel system. The ceramic composites are to be formed using a chemically reacted magnesium/phosphate binder system in combination with industrial waste ash and lightweight expanded clay aggregates. The rheological and mechanical properties of the ceramic composites will be characterized based on standardized test procedures adopted from the concrete industry. Analytical relationships will be developed between the mix proportions, the mix procedures and the obtained properties. In later stages of the project, structural panels formed from alternating layers of the ceramic composites and glass fibre reinforcing fabrics will be developed and tested to failure under bending. The influence of panel composition and panel configuration on the structural behaviour will be examined. Analytical models which can accurately represent the strength and stiffness of the panels will be developed based on the measured mechanical properties of the constiuent materials. By considering possible replacement of non-structural Oriented Strand Board or Plywood sheathing in house construction as a target application, large-scale panels will be developed for implementation in field trials.
