IACMI宣布合作项目，在制造业中创新智能复合材料压力容器
这项技术合作的目标是开发结构可预测，低成本的智能复合材料压力容器（SCPV），同时采用集成，可靠的健康监测，同时不影响安全性。该项目利用智能光纤传感器技术，由Dayakar Penumadu教授在田纳西州诺克斯维尔大学集成和开发，以优化碳纤维平移，然后整合该技术，实现疲劳相关性能的按需反馈。Steelhead Composites将利用ORNL的复合加工经验优化容器装配中的监控程序。这种经过验证的技术可用于降低在燃料电池汽车和运输市场中的其他应用中采用复合压力容器的成本。
在整个项目中，集成系统将允许持续监测船舶的健康状况，保持循环寿命特征的持续记录，并提供船舶结构的即时反馈，以应对由低能量或高能量冲击引起的任何意外损坏。
“目前，CPV安全性是以航空航天功能作为基准应用来衡量的。通过该项目开发的持续和可预测的健康监测旨在提高运营安全性并降低这些船舶在汽车领域的成本。“Steelhead Composites，LLC工程总监Kaushik Mallick博士说。
该项目的终目标是使船舶的安全设计因素具有更高的可信度，从而降低与这些临界承压复合结构相关的成本。
复合材料研究所席执行官约翰·霍普金斯说：“在运输市场广泛采用CPV，必须彻底验证特定应用的安全标准。” “作为该项目合作伙伴的IACMI成员拥有丰富的经验和技术研究能力，可以帮助推动这种应用，”霍普金斯详细介绍说。
该过程开发的方法将为结构健康监测系统与碳纤维压缩气体复合材料行业的整合开辟新的机会。项目成果可以使私营企业通过有效测试在大批量应用中开发复合材料压力容器所使用的材料和工艺来创新制造过程。
Steelhead主导的项目部分得到了IACMI合作伙伴的支持，包括科罗拉多州经济发展和国际贸易办公室（COEDIT）和田纳西州经济和社区发展部。这些合作伙伴通过支持IACMI及其成员来促进创新。

The Institute for Advanced Composites Manufacturing Innovation (IACMI), announces a project to develop Smart Composite Pressure Vessels (SCPV) with integrated health monitoring. The project is led by Steelhead Composites, with the project team including Teijin Carbon, Oak Ridge National Laboratory (ORNL), and the University of Tennessee, Knoxville (UT).
The goal of this technical collaboration is to develop structurally predictable, low-cost smart composite pressure vessels (SCPVs) without compromising safety by employing integrated, reliable health-monitoring. The project leverages smart fiber optic sensor technology, integrated and developed at the University of Tennessee, Knoxville by Professor Dayakar Penumadu to optimize carbon fiber translation and to then integrate this technology, enabling on-demand feedback on fatigue related performance. Steelhead Composites will utilize ORNL’s composite processing experience to optimize monitoring procedures in the vessel assembly. This validated technology can then be used to lower the cost of adopting composite pressure vessels in fuel cell cars and other applications in transportation markets.
Throughout this project, the integrated system will allow for continuous monitoring of the vessel’s health, maintain an ongoing record of cycle life characteristics, and provide immediate feedback on the vessel’s structure in response to any unplanned damage caused by either low or high energy impact.
“Currently, CPV safety is measured with aerospace functions as the baseline application. The continuous and predictable health-monitoring that will be developed through this project seeks to enhance operational safety and reduce the cost of these vessels in the automotive sector.” said Dr. Kaushik Mallick, Director of Engineering at Steelhead Composites, LLC.
The ultimate goal of this project is to allow for higher confidence in the safety design factor of the vessels, thereby reducing the cost associated with these critical pressure-bearing composite structures.
“Thorough validation of application-specific safety standards is necessary for broad adoption of CPVs in transportation markets,” said John A. Hopkins, CEO of the Composites Institute. “The IACMI members who are partners in this project have the experience and technical research capabilities to make help drive this adoption,” detailed Hopkins.
The method developed by this process will open new opportunities for the integration of structural health-monitoring systems into the carbon fiber compressed gas composites industry. Project outcomes can enable private industry to innovate the manufacturing process through effectively testing the materials and processes utilized in the development of composite pressure vessels in higher volume applications.
The Steelhead-led project is supported in part through IACMI state partners including the Colorado Office of Economic Development and International Trade (COEDIT) and Tennessee Department of Economic and Community Development. These state partners catalyze innovation by supporting IACMI and its members.
