The production of glass is a highly energy intensive process consuming approximately 7 TWh of energy in the UK annually. Glass is a relatively dense material and therefore also consumes significant energy during transport. One of the limitations in the use of glass is its strength. Being a brittle material, surface defects with dimensions in the order of microns can lead to catastrophic failure. If glass was stronger, less glass would be required to achieve the same strength in a given glass article, therefore reducing the energy required to make the article, reducing the energy to transport the article and reducing the weight of the structure required to support the article (e.g. building or vehicle support materials) further reducing the energy required for the overall structure. C-Bond is an American Corporation that has developed a glass surface treatment that, in combination with a laminated film, provides significant increase in ballistic protection. The formulation uses a combination of additives, including modified silane molecules, surfactants with specific size distributions and carbon nanotubes to facilitate both mechanical keying and chemical bonding to the glass substrate. This not only forms a protective layer to prevent defects but 'holds' surface cracks together to prevent them propagating into the bulk. Experimental work indicates potential strength increases of >200%, implying that the thickness of treated glass articles could be reduced by 50-60% and maintain strength. In reality there are more complex issues involved, for example the need to maintain rigidity, which this treatment would not affect, so the overall reduction is more likely to be 20-30%. However, if an average of 15% reduction could be achieved in all glass products in the UK then approximately 1 TWh would be saved annually. This project aims to explore a range of glass applications to examine the potential benefit of apply C-Bond material to increase strength and thereby reduce energy use. The primary focus will be on flat glass (architectural, automotive and aerospace) and containers (bottles and jars); these 2 sectors account for 90% of glass production in the UK. Other potential applications of this technology are domestic glass and pharmaceutical packaging; in both cases the interest will be to reduce breakage, rather than reduce weight.

玻璃的生产是一个高度能源密集型的过程，在英国每年消耗约7 TWh的能源。玻璃是一种相对致密的材料，因此在运输过程中也消耗大量的能量。玻璃使用的局限性之一是它的强度。作为一种脆性材料，尺寸在微米量级的表面缺陷可能导致灾难性的故障。如果玻璃更强，则在给定的玻璃制品中实现相同的强度将需要更少的玻璃，因此降低了制造制品所需的能量，降低了运输制品的能量，并且降低了支撑制品所需的结构（例如建筑或车辆支撑材料）的重量，进一步降低了整体结构所需的能量。C-Bond是一家美国公司，它开发了一种玻璃表面处理，与层压膜相结合，可显著提高防弹性能。该配方使用了多种添加剂的组合，包括改性硅烷分子、具有特定尺寸分布的表面活性剂和碳纳米管，以促进与玻璃基板的机械键合和化学键合。这不仅形成了一个保护层，以防止缺陷，但“持有”表面裂纹在一起，以防止他们蔓延到散装。实验工作表明潜在的强度增加> 200%，这意味着经处理的玻璃制品的厚度可以减少50-60%并保持强度。实际上，涉及到更复杂的问题，例如需要保持刚性，这种处理不会影响刚性，因此总体减少更可能是20- 30%。然而，如果英国所有玻璃产品的平均减排量能够达到15%，那么每年将节省约1 TWh。该项目旨在探索一系列玻璃应用，以研究应用C-Bond材料以提高强度从而减少能源使用的潜在好处。主要重点将放在平板玻璃（建筑，汽车和航空航天）和容器（瓶和罐）上;这两个行业占英国玻璃产量的90%。这项技术的其他潜在应用是家用玻璃和药品包装;在这两种情况下，利益将是减少破碎，而不是减轻重量。
