This application proposes a comprehensive research program for producing renewable resource-based carbonaceous biocomposites that are significantly lighter (e.g. ~20%) than their petro-based glass fiber composite counterparts for automotive parts manufacturing. Every pound of weight saving is beneficial to automakers as they strive to achieve new corporate average fuel economy (CAFE) standards, a fleet average of 54.5 mpg by 2025. To exploit the benefits of biocomposite materials in terms of their lightweighting, renewability, low carbon footprint and reduced greenhouse gas (GHG) emission this program will apply rigorous, creative science to solve critical technical barriers.***The applicant proposes to re-invent biocomposites through a new diversified approach where thermo-chemical biomass conversion (pyrolysis) will be utilized to overcome the challenges associated with the use of biofibres for composite applications. The dominant constraints for natural fibres in current biocomposite uses are: unwanted odor and aesthetics in their finished products, low temperature resistance limiting their uses for engineering plastic reinforcements, hydrophilicity and supply chain issues. The implementation of novel ideas to exploit maximum value from non-food and waste biomasses for carbonaceous biobased reinforcements is the focus here to address both the supply and demand gap in addition to achieving performance attributes requirements for auto-part uses.***Unlike other research activities on pyrolysis across the world that mainly focus on energy recovery, this program focuses on cutting-edge sustainable materials. The experimental method is to fabricate novel biocomposites by combining biobased blend matrix systems with hierarchical (macro-micro-nano) reinforcement obtained from hybrid reinforcements of torrefied biomass (through low temperature pyrolysis) in conjunction with nano- and micro-biocarbon (obtained through high temperature pyrolysis). The research will create long term competitive advantage enabling novel biocomposite uses in high volume industrial applications.***The proposed research activities are timely, innovative and at the leading edge internationally. Research outcomes will contribute to fundamental knowledge discovery in the area of design and engineering of biocomposites that encompass biopolymer blends, compatibilization and additive use for durability, green surface modifications, processing technologies, molecular structure and functional performance. This cross-disciplinary program will develop HQP by stimulating team-based creative solutions to well-defined technical obstacles. Through working with industry to understand scale-up and other real world requirements, HQP will improve their fundamental knowledge in order to be future leaders on the leading edge of industrial use of advanced biocomposite science.**

该申请提出了一项综合研究计划，用于生产基于可再生资源的碳质生物复合材料，该复合材料比用于汽车零部件制造的石油基玻璃纤维复合材料轻得多（例如~20%）。每一磅的减重都对汽车制造商有利，因为他们努力实现新的企业平均燃油经济性 (CAFE) 标准，到 2025 年车队平均燃油经济性达到 54.5 英里/加仑。为了充分利用生物复合材料在轻量化、可再生性、低碳足迹和减少温室气体 (GHG) 排放方面的优势，该计划将应用严格的、创造性的科学来解决关键的技术障碍。***申请人建议 通过一种新的多样化方法重新发明生物复合材料，其中将利用热化学生物质转化（热解）来克服与将生物纤维用于复合材料应用相关的挑战。当前生物复合材料用途中天然纤维的主要限制是：成品中不良气味和美观、耐低温性限制其在工程塑料增强材料中的使用、亲水性和供应链问题。除了满足汽车零部件用途的性能属性要求之外，实施新想法以从非食品和废弃生物质中挖掘最大价值来生产碳质生物基增强材料是解决供需缺口的重点。***与世界各地主要关注能源回收的其他热解研究活动不同，该计划侧重于尖端可持续材料。该实验方法是通过将生物基共混基质系统与分层（宏观-微米-纳米）增强材料相结合来制造新型生物复合材料，该分层增强材料是通过烘焙生物质（通过低温热解）与纳米和微生物碳（通过高温热解获得）的混合增强材料获得的。该研究将创造长期的竞争优势，从而在大批量工业应用中实现新型生物复合材料的用途。***拟议的研究活动是及时的、创新的并且处于国际领先地位。研究成果将有助于生物复合材料设计和工程领域的基础知识发现，包括生物聚合物共混物、相容性和耐久性添加剂的使用、绿色表面改性、加工技术、分子结构和功能性能。这个跨学科项目将通过激发基于团队的创造性解决方案来解决明确的技术障碍来开发 HQP。通过与业界合作了解规模扩大和其他现实世界的需求，HQP 将提高他们的基础知识，以便成为先进生物复合科学工业应用前沿的未来领导者。 **
