We have developed using our EPRSC grant (EP/F032005/1) an elegant, intrinsically scalable and cost-effective technology for binding fibres together in order to create an in-plane non-woven fibre mat, utilising bacterial nanocellulose - itself a structural reinforcement, with no extra chemical steps involved during the production. The invention was originally developed for binding natural fibres - such as sisal and hemp - to create "truly green", hierarchical composites. Bacterial cellulose (BC) is currently produced on commercial scale (10t/a) for cosmetic applications by fzmb GmbH. BC has very impressive properties, both in paper form (15 GPa tensile modulus) and as an individual nanofibre (114 GPa Young's modulus). Alternatively, nanofibrillated cellulose (NFC) is also available at the pilot scale. There is sufficient evidence in the literature that nanocellulose nanocomposites with much improved properties can be made. In addition to this, it has been shown that hierarchical, i.e. fibre reinforced, nanocomposites can be produced using BC. The previous work has resulted in two patents. The proposed project will demonstrate a slurry dipping or "paper-making" process to produce short (non-woven) fibre preforms. The advantage of our process is that short, long and even continuous fibres can be utilised to produce fibre preforms, which can be utilised in conventional composite making processes. The fibres, which can be used can be either be natural or synthetic. The ideal candidates for this project are fibres that can only with difficulties be formed in to mechanically strong fibre preforms with the required strength for downstream handling. We will focus on scaling up our development of producing fibre preforms and provide a range of value-added properties to this technology. Examples will be selected to satisfy the requirement of the industry and to stimulate new applications for fibre reinforced (nano)composites. We believe that our technology can be licensed to composites manufacturers who will benefit from a new generation of value added products and a major competitive advantage.

我们利用我们的EPRSC拨款（EP/F032005/1）开发了一种优雅的，本质上可扩展的和具有成本效益的技术，用于将纤维结合在一起，以创建平面内无纺布纤维垫，利用细菌纳米纤维素-本身是一种结构增强剂，在生产过程中不涉及额外的化学步骤。这项发明最初是为了粘合天然纤维，如剑麻和大麻，以创造“真正的绿色”，分层复合材料。细菌纤维素（BC）目前由fzmb GmbH以商业规模（10t/a）生产用于化妆品。BC具有非常令人印象深刻的性能，无论是纸质形式（15 GPa拉伸模量）还是作为单个纳米纤维（114 GPa杨氏模量）。另外，纳米纤维化纤维素（NFC）也可用于中试规模。文献中有充分的证据表明，纳米纤维素纳米复合材料的性能可以得到很大的改善。除此之外，它已经表明，分层，即纤维增强，纳米复合材料可以使用BC生产。之前的工作已经获得了两项专利。拟议的项目将展示一种浆液浸渍或“造纸”工艺，以生产短（无纺布）纤维预制体。我们的工艺的优点是，短纤维、长纤维甚至连续纤维都可以用来生产纤维预制品，这些预制品可以用于传统的复合材料制造工艺。可以使用的纤维可以是天然的，也可以是合成的。该项目的理想候选材料是那些难以形成具有下游处理所需强度的机械强度纤维预制体的纤维。我们将专注于扩大我们生产纤维预制体的开发，并为这项技术提供一系列增值特性。将选择实例来满足工业的要求，并刺激纤维增强（纳米）复合材料的新应用。我们相信，我们的技术可以授权给复合材料制造商，他们将受益于新一代的增值产品和主要的竞争优势。
