项目摘要

Shape memory polymers (SMP) can store a temporary shape and restore their original shape upon application of an external stimulus, such as heat. SMP offer important advantages over other shape memory materials, such as shape memory alloys. Some of these advantages are lightweight, relatively higher strain recover-ability, easier tailorable properties, and manufacturability. They have the great potential to be utilized in applications, such as unmanned air vehicles (UAV), morphing aircraft components, and biomedical stents, to name a few. The bottleneck in their broader utilization is their inherently low mechanical properties and shape recovery forces (SRF), and a fundamental understanding of their properties in actual “field applications” as a function of humidity, temperature, etc. These important aspects need to be addressed and documented in detail for critical applications, and this is the main motivation behind this proposal for our research program.Most SMP are affected by humidity; therefore, we conducted detailed studies to identify its effects on SMP. Additionally, we studied the effect of print parameters on the properties of the SMP printed using extrusion based additive manufacturing (EBAM) technique. SMP-composites (SMPC) are reinforced SMP and have higher mechanical properties and SRF compared to SMP. My group has been working towards production and characterization of multifunctional SMPC produced by EBAM technique for a number of years. Building on to the knowledge and expertise we have developed, this proposal is prepared to address the aforementioned shortcomings.The main objectives of the proposed research program are: (a) to produce and characterize fiber reinforced SMPC using EBAM; (b) to develop a model to predict the properties of SMPC; (c) to produce SMPC with integrated heating elements to facilitate field activations, and to investigate the resistance of the heating elements for structural health monitoring (SHM) capability.The novelty and significance of the proposed program originate from its promise to provide a strong analytical and experimental understanding of the SMPC. This will provide a large experimental database not only for this program but also for the researchers and engineers that work with SMPC for years to come. The analytical model will be a simple yet accurate model that is unfortunately currently missing in the literature and intended to be a pioneering work in the field. The proposed activation technique and SHM capabilities will make these novel materials true multifunctional SMPC. Consequently, the proposal will provide a way forward to take these materials out of the laboratories to actual field applications by promoting scientific knowledge based use of SMPC in the aforementioned strategically critical applications. The program will make significant contributions to the advancement of knowledge in Canada and around the world.
形状记忆聚合物(SMP)可以存储临时形状并在施加外部刺激(例如热量)时恢复其原始形状。与形状记忆合金等其他形状记忆材料相比,SMP 具有重要的优势。其中一些优点是重量轻、相对较高的应变恢复能力、更容易定制的特性和可制造性。它们在无人机(UAV)、变形飞机部件和生物医学支架等应用中具有巨大的潜力。其更广泛应用的瓶颈在于其固有的低机械性能和形状恢复力 (SRF),以及对其在实际“现场应用”中作为湿度、温度等函数的性能的基本了解。对于关键应用,需要详细解决和记录这些重要方面,这也是我们研究计划提案背后的主要动机。大多数 SMP 都会受到湿度的影响;因此,我们进行了详细的研究来确定其对 SMP 的影响。此外,我们还研究了打印参数对使用基于挤出的增材制造 (EBAM) 技术打印的 SMP 性能的影响。 SMP 复合材料 (SMPC) 是增强型 SMP,与 SMP 相比具有更高的机械性能和 SRF。我的团队多年来一直致力于通过 EBAM 技术生产多功能 SMPC 的生产和表征。基于我们所开发的知识和专业知识,该提案旨在解决上述缺点。拟议研究计划的主要目标是: (a) 使用 EBAM 生产纤维增强 SMPC 并对其进行表征; (b) 开发一个模型来预测 SMPC 的特性; (c) 生产带有集成加热元件的 SMPC,以促进现场激活,并研究加热元件的电阻以实现结构健康监测 (SHM) 能力。该计划的新颖性和意义源于其承诺提供对 SMPC 的强大分析和实验理解。这不仅为本项目提供了一个大型实验数据库,也为未来几年与 SMPC 合作的研究人员和工程师提供了一个大型实验数据库。该分析模型将是一个简单而准确的模型,不幸的是目前在文献中缺失,并且旨在成为该领域的开创性工作。所提出的激活技术和 SHM 功能将使这些新型材料成为真正的多功能 SMPC。因此,该提案将提供一条前进的道路,通过促进基于科学知识的 SMPC 在上述战略关键应用中的使用,将这些材料从实验室带到实际的现场应用。该计划将为加拿大和世界各地的知识进步做出重大贡献。
