Commingled Biomaterials from Nature (COMBINE)

为了实现总体目标，项目被分解为一系列相互关联的技术任务，每个任务都开发生产可持续产品所需的生产过程（和使能技术）的一个步骤。为了确保材料和组件的技术发展，将研究许多路线，从低端技术开始，如通过混合和编织多年的薄膜堆叠，最后研究和开发案例研究组件的成型技术。该项目的主要产出将是完全由可再生自然资源制造的可持续结构部件。其他关键成果将是结构编织的天然织物，可堆肥的生物衍生热塑性聚合物纤维，以及由这些天然纤维和聚合物制成的紧密混合的纱线/织物。研究将具体完成：大麻和亚麻纤维将被梳理和精梳，以提供合适的纺纱材料。最初，将研究市售天然纤维与市售树脂系统的相容性。将对商业系统的特性进行测试，以检查与树脂系统的适用性。研究现有的树脂体系，包括传统的热塑性聚合物和生物衍生热塑性塑料。研究的两个系统都将进行测试，以提供有关熔体温度和流动的详细信息，从而可以深入了解系统确定已开发纤维的能力。所研究的商业系统将测试其与纤维的兼容性。将研究创新的纺纱方法，以提供具有正确性能的结构天然纤维纱线，以允许浸渍并提供所需的结构性能。将采用各种混合方法来提供充分混合的纤维和基体体系。这项任务还包括为复合材料应用创造具有最佳捻度的纺纱。与纺织应用中使用高捻度的复合材料不同，需要最小的捻度，因为高捻度会导致纤维的离轴载荷，从而降低层压性能以及纱线浸渍问题。在所有系统中，对所得到的优化纱线的织造进行调查。树脂和纤维的加工特性的调查和发展将通过加工方法，包括薄膜堆积，真空巩固和压缩成型进行。最终形成的斑块将进行整理技术和使能技术（如连接）的测试。还将研究可回收性和可堆肥性。案例研究组件将被指定并使用适当的加工方法制造，然后完成的组件将与传统材料进行测试，例如玻璃纤维增强聚酯，目前用于生产组件。

To achieve the overall objective the project is broken down into a series of inter-related technical tasks, each developing a step of the production process (and enabling technologies) needed to produce sustainable products. A number of routes will be investigated to ensure the technical development of the materials and components, starting with low end technologies such as film stacking through commingling and weaving of years, and finally investigating and developing moulding techniques for the case study components. The main output from this project will be sustainable structural parts manufactured entirely from renewable natural resources. Other key results will be structural woven natural fabrics, a compostable, bio-derived thermoplastic polymer fibre, and intimately mingled yarns/fabrics from these natural fibres and polymers. Research will be completed specifically on: Hemp and flax fibres will be carded and combed to provide suitable materials for spinning. Initially commercial available natural fibres will be investigated for compatibility with commercially available resin systems. Tests will be carried out on the characteristics of the commercial systems to check for suitability with the resin systems. Investigations into resin systems available, including traditional thermoplastic polymers and bio-derived thermoplastics. Both the systems investigated will be tested to provide detailed information on melt temperatures and flow, which in turn may provide insight into the capabilities of the systems to set out the developed fibres. The commercial systems studied will be tested for compatibility with the fibres. Innovative methods of spinning will be researched to provide structural natural fibre yarns with correct properties to allow impregnation and provide the structural properties required. Various methods of mingling will be employed to provide adequately mixed fibre and matrix systems.This task aslo involves the creation of a spun yarn with optimal twist for composite applications. Unlike textile applications where a high twist is used for composites a minimum twist is needed as high twist leads to off-axis loading of the fibres and hence a reduction in laminate properties as well as problems in yarn impregnation. Investigation into the weaving of the resultant optimised yarns will be completed in all systems. Investigation and development of the processing characteristics of the resin and fibres will be undertaken through processing methods including film stacking, vacuum consolidation and compression moulding. Resultant plaques formed will be tested for finishing techniques and enabling technologies such as joining. Recyclability and compostability will also be studied. Case study components will be specified and manufactured utilising appropriate processing methods, the completed components will then be tested against the traditional materials, such as glass fibre reinforced polyester, used to currently produce the components.
