Workshop on Performance and Design of Fiber Reinforced Polymer Composites at Very Cold Temperatures

纤维增强聚合物（FRP）复合材料，用于各种应用和环境，往往选择比传统材料的耐久性。特别是在寒冷的温度下，与传统材料相比，设计师期望FRP复合材料的使用寿命更长，维护成本更低。然而，玻璃钢复合材料的性能会受到环境的不利影响。例如，在民用基础设施的应用中，除了冻融引起的湿气膨胀和干燥外，道路盐的沉积还会加剧刚度和强度的退化。这种影响的长期性能和设计的含义必须很好地理解FRP复合材料在非常寒冷的温度下的成功实施。建议的目标是：1。定义FRP复合材料在极冷温度下的行为和性能预测的最新技术2。识别关于行为和预测的知识库中的空白3。基于FRP复合材料和其他低温材料的现有知识基础，激发研究和合作的想法。起草一份关于低温下FRP复合材料性能和设计的综合研究计划拟议的研讨会的智力价值在于将具有不同专业知识的研究人员聚集在一起，并整合不同主题领域的知识，以推进最新技术的发展。FRP复合材料在极低温下的性能和设计研究涵盖了材料工程、制造、预测建模和基于可靠性的措施，以纳入设计程序。私家侦探有一个很好的计划来确定合适的人。在影响更广泛的领域，讲习班将通过改进FRP复合材料在低温下的应用使社会受益，在低温下FRP优于传统材料的好处可以充分实现。

Fiber-Reinforced Polymer (FRP) composites, used in various applications and environments, are often chosen over conventional materials for their durability. In cold temperatures, especially, designers expect longer lifetimes and lower maintenance for FRP composites as compared to conventional materials. However, the performance of FRP composites can be adversely affected by environment. For applications in civil infrastructure, for example, stiffness and strength degradation can be aggravated by deposits from road-salts in addition to moisture induced swelling and drying from freeze-thaw. The implications of such effects for long-term performance and design must be well understood for successful implementation of FRP composites at very cold temperatures.The proposed objectives are:1. Define the state of the art with regards to behavior and prediction of performance of FRP composites at very cold temperatures2. Identify gaps in the knowledge base regarding behavior and prediction3. Stimulate ideas for research and collaboration based on the existing knowledge base of FRP composites and other materials at very cold temperatures4. Draft an integrated research plan for performance and design of FRP composites at very cold temperaturesThe intellectual merit of the proposed workshop lies in the bringing together of researchers with diverse expertise and the integration of knowledge in different topic areas to advance the state of the art. The study of the performance and design of FRP composites at very cold temperatures spans materials engineering, manufacturing, predictive modeling, and reliability-based measures for incorporation into design procedures. The PI has a good plan to identify the right people.In the area of broader impacts, the workshop will benefit society through improved application of FRP composites at cold temperatures, where the benefits of FRP over conventional materials can be fully realized.
