Development and characterization of layered sandwich panel system with ceramic core

点击翻译按钮获取中文摘要

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.
