项目摘要

This proposal seeks funding for investigations into the structure and mechanical properties of carbon-nanostructures produced from natural biomass sources and by novel processing techniques. Carbon fibres produced by these routes are attractive since they are cheaper than those obtained by conventional routes (PAN or pitch-based), are derived from a renewable resource and since native cellulose is often already structured, it is an attractive precursor material. In addition to this, native sources of cellulose, such as bacterial, tunicate and derived sources from plant material in the form of whiskers, have fibre diameters in the nanometer range. This enables very slender fibres to be produced which can offer high stiffnesses and strengths. Other sources of nanofibres, such as from CNTs (carbon nanotubes) are expensive to produce, and as such there are significant advantages to the approaches we will investigate. The use of these materials for high performance composites will be investigated using non-contact methods and novel approaches to better understand the interface between materials. Low-cost approaches to the development of high-throughput methods of producing fibres will be addressed, with particular emphasis on enabling the enhancement of material properties from waste and cheaply generated biomass. Additional adventurous research will be conducted on the manipulation and deformation of the nanostructures using a FIB (Focussed Ion Beam) system. The project will fund a postdoctoral research associate for 4 years who will be based in the Materials Science Centre, School of Materials, University of Manchester. No systematic programme of research into the capability of these materials has been investigated in this manner and as such the impact will be both of mutual academic and industrial relevance. In terms of industrial involvement we have the support of five industrial companies (Borregaard - supplier; Technical Fibre Products / end user; Renishaw - technology and Lenzing - suppliers and technology).

该提案寻求资金，用于研究由天然生物质来源和新加工技术生产的碳纳米结构的结构和机械性能。通过这些途径生产的碳纤维是有吸引力的，因为它们比通过常规途径（PAN或沥青基）获得的那些更便宜，来源于可再生资源，并且由于天然纤维素通常已经结构化，因此它是有吸引力的前体材料。除此之外，纤维素的天然来源，例如细菌、被囊动物和晶须形式的来自植物材料的衍生来源，具有纳米范围内的纤维直径。这使得能够生产非常细长的纤维，其可以提供高刚度和强度。其他来源的纳米纤维，如从CNT（碳纳米管）是昂贵的生产，因此有显着的优势，我们将研究的方法。将使用非接触方法和新方法研究这些材料用于高性能复合材料，以更好地了解材料之间的界面。将讨论开发高产量纤维生产方法的低成本方法，特别强调能够从废物和廉价产生的生物质中提高材料性能。另外的冒险研究将使用FIB（聚焦离子束）系统对纳米结构进行操纵和变形。该项目将资助一名博士后研究助理4年，他将在曼彻斯特大学材料学院材料科学中心工作。没有系统的研究方案，这些材料的能力已经调查，以这种方式，因此，影响将是相互的学术和工业相关性。在工业参与方面，我们得到了五家工业公司的支持（Borregaard -供应商; Technical Fibre Products /最终用户; Renishaw -技术和伦辛-供应商和技术）。
