项目摘要

Glass is a ubiquitous material in building envelopes, where it is typically used in multiple flat plates to form insulated glazing units (IGUs) that are simply supported by rectilinear framing members. Despite recent technological improvements in this field, state-of-the-art glazing systems fail to make efficient use of materials, have a low robustness, a relatively high thermal conductivity, and are rarely recycled.Recent research developments in glass engineering, adhesive bonding and fibre-reinforced polymer (FRP) composites provide an opportunity to explore a novel combination of these materials in the form of FRP-glass composite structures. These consist of glass plates that are bonded to pultruded FRP profiles by means of high strength - high stiffness thermosetting adhesives, thereby forming an FRP-glass composite panel . This is a novel, yet relatively simple concept, but it involves a radical shift in the role of glass in buildings: from its current use as an inefficient infill panel in a layered system, to a structurally and thermally efficient component within a robust and recyclable composite structure.The aim of this 24 month project is two-fold: Firstly to characterise the thermo-mechanical properties and environmental impact of a first generation, yet novel, form of composite FRP-glass panel; and secondly to explore the feasibility of more adventurous second generation composite glass panels. The latter offer further improvements over the basic FRP-glass panels, in terms of structural performance, adaptability and recyclability. This aim will be achieved by means of coordinated thermo-mechanical investigations involving physical experiments, numerical modelling and theoretical analyses at three levels: (1) material level, (2) FRP-glass connection level; and (3) full-scale composite glass panel level, The evaluation of the potential benefits of composite glass panels and the fundamental properties characterised in this project will: (1) provide a basis for future research and product development in this new sub-field; (2) help produce novel glazed building envelopes that significantly out-perform existing state-of the-art glazing systems; (3) lead to step-change improvements in the sustainability and resilience of new and existing buildings.

玻璃是建筑物围护结构中普遍存在的材料，其中它通常用于多个平板中以形成由直线框架构件简单支撑的隔热玻璃单元（IGU）。尽管最近在该领域取得了技术进步，但最先进的玻璃窗系统未能有效利用材料，坚固性低，热导率相对较高，并且很少回收。玻璃工程、粘合剂粘合和纤维增强聚合物（FRP）的最新研究进展复合材料提供了一个机会，可以探索这些材料以玻璃纤维增强塑料-玻璃复合结构形式的新型组合。这些由玻璃板组成，玻璃板通过高强度-高刚度热固性粘合剂粘合到拉挤FRP型材上，从而形成FRP-玻璃复合板。这是一个新颖但相对简单的概念，但它涉及到玻璃在建筑中的角色的根本转变：从目前在分层系统中作为低效填充面板的使用，到坚固且可回收的复合结构中的结构和热效率组件。这个为期24个月的项目的目标是双重的：第一，验证第一代新型复合FRP-玻璃面板的热机械性能和环境影响;第二，探讨第二代复合玻璃板的可行性。后者在结构性能、适应性和可回收性方面比基本的玻璃纤维增强塑料板有了进一步的改进。这一目标将通过协调的热机械研究来实现，包括三个层面的物理实验、数值模拟和理论分析：（1）材料层面;（2）玻璃纤维增强塑料-玻璃连接层面;和（3）全尺寸复合玻璃面板层面。（1）为这一新领域的未来研究和产品开发提供基础;（2）帮助生产新型玻璃建筑围护结构，其性能显著优于现有最先进的玻璃系统;（3）导致新建筑和现有建筑的可持续性和弹性的逐步改善。
