项目摘要
Conventional engineering materials, like metals and plastics, typically trade toughness for strength. This represents a challenge in demanding engineering applications where both strength and toughness are required. Natural composite biomaterials like bone, antler, and nacre serve as inspiration in the pursuit of high performance and durable materials because they are stiff, strong and tough. They also compete with metals when compared in terms of “strength to weight ratios”. Theoretical modeling has provided insights into the composition and multi-scale structure required to achieve their desirable properties. Recent studies have resulted in potential “design guidelines” for synthetic hierarchical biomimetic composites. But can these design guidelines be applied? This is the fundamental engineering challenge addressed in this proposal. A nacre-like biomimetic composite with remarkable mechanical properties comparable to some metal alloys has been produced using freeze casting but the process lacks adaptability and versatility. Additive manufacturing can overcome these limitations.***The Objective of the proposed research program is to produce and test hierarchical, multi-scale biomimetic composites and to subsequently enable novel, disruptive technologies for their design, production and application in various fields of engineering.***Two specific objectives are:***A) Expedient testing and verification of hierarchical biomechanics-derived “design guidelines” using conventional and well-understood engineering polymer systems combined with commercially available inorganic particles and novel interface coupling agents.***B) Development of “by design” approaches for production of biomimetic composites that highly mimic but mechanically outperform cortical bone.******Novel “designed” biomimetic composites will be produced using direct write assembly. By the precise extrusion of novel inks, filaments on the order of 100 microns in diameter will be printed. Composites will be assembled in a layer by layer fashion. The structures of the composites will be characterized and tested using state-of-the-art methods. The structure and mechanical behaviour will be compared to the “design guideline” model predictions and model materials. This is a bottom-up, “by design” approach.***It is broadly agreed that synthetic biomimetic composite materials have the potential to revolutionize many fields of engineering due to their predicted superior mechanical properties if they can be produced efficiently and effectively. This research program will initiate a path to the practical and adaptable design and production of durable, high performance biomimetic composite materials. Such innovation will help drive Canada's economy as we shift from a natural resource base to a knowledge/innovation base in the future. Ten HQP will be trained during the 5 years of the program.***********
传统的工程材料,如金属和塑料,通常以韧性换取强度。这在需要强度和韧性的苛刻工程应用中是一个挑战。天然复合生物材料,如骨头,鹿角和珍珠层,是追求高性能和耐用材料的灵感,因为它们坚硬,坚固和坚韧。在“强度重量比”方面,它们也与金属竞争。理论建模提供了深入了解所需的成分和多尺度结构,以实现其理想的性能。最近的研究导致了潜在的“设计准则”的合成层次仿生复合材料。但是,这些设计准则是否适用?这是本提案中解决的基本工程挑战。利用冷冻铸造法制备了一种具有与某些金属合金相当的优异力学性能的仿珍珠质仿生复合材料,但该工艺缺乏适应性和通用性。增材制造可以克服这些限制。拟议研究计划的目标是生产和测试分层、多尺度仿生复合材料,并随后为其在各个工程领域的设计、生产和应用提供新颖的、颠覆性技术。*两个具体目标是:*A)使用常规的和熟知的工程聚合物系统与市售无机颗粒和新型界面偶联剂相结合,对分层生物力学衍生的“设计指南”进行方便的测试和验证。B)开发“通过设计”的方法来生产高度模仿但机械性能优于皮质骨的仿生复合材料。**新的“设计”仿生复合材料将使用直接写入组装。通过新型油墨的精确挤出,将印刷直径为100微米量级的细丝。复合材料将以逐层方式组装。复合材料的结构将使用最先进的方法进行表征和测试。将结构和机械性能与“设计指南”模型预测和模型材料进行比较。这是一种自下而上的“设计”方法。*人们普遍认为,合成仿生复合材料具有革命性的许多领域的工程,由于其预测的上级机械性能,如果他们可以有效地生产。该研究计划将开创一条实用和适应性强的耐用,高性能仿生复合材料的设计和生产之路。这种创新将有助于推动加拿大的经济,因为我们将从自然资源基础转向知识/创新基础。10名HQP将在该计划的5年期间接受培训。
