FRP-Glass Composite Structures

玻璃是建筑围护结构中普遍存在的一种材料，它通常用于多个平板中，形成简单由直线框架构件支撑的绝缘玻璃单元(IGU)。尽管最近这一领域的技术进步，但最先进的玻璃系统不能有效地利用材料，具有较低的坚固性，相对较高的导热系数，并且很少被重复使用。最近在玻璃工程、粘接和纤维增强聚合物(FRP)复合材料方面的研究进展为探索以FRP-玻璃复合材料形式的这些材料的新组合提供了机会。这些玻璃板由玻璃板组成，通过高强度、高刚性的热固性粘合剂将玻璃钢型材粘合在一起，从而形成玻璃钢-玻璃复合板。这是一个新颖但相对简单的概念，但它涉及到建筑中玻璃角色的根本性转变：从目前在分层系统中作为低效填充面板的使用，转变为在坚固和可回收的复合结构中的结构和热高效组件。这个24个月的项目有两个目标：第一，表征第一代但新颖的复合玻璃钢面板的热机械性能和环境影响；第二，探索更具冒险精神的第二代复合玻璃面板的可行性。后者在结构性能、适应性和可回收性方面比基本的玻璃钢面板有进一步的改进。这一目标将通过三个层面的协调热机械研究来实现，包括物理实验、数值模拟和理论分析：(1)材料层面；(2)玻璃钢-玻璃连接层面；和(3)全尺寸复合玻璃面板层面，对复合玻璃面板的潜在效益和本项目所描述的基本性能的评估将：(1)为这一新领域的未来研究和产品开发提供基础；(2)帮助生产性能显著优于现有最先进玻璃系统的新型玻璃建筑围护结构；(3)逐步改善新建和现有建筑的可持续性和复原力。

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.
