The goal of this research is to evaluate the potential of Raman spectroscopy as a method of condition assessment for carbon fiber composite materials used in high performance situations such as composite overwrapped pressure vessels (COPVs). There are currently limited nondestructive evaluation (NDE) technologies to evaluate these composite materials in situ. Variations in elastic strain in the composite material can manifest from degradation or damage, and as such could provide a tool for condition assessment. The characterization of active Raman bands and the strain sensitivity of these bands for commercially available carbon fibers are reported.

Initially, the materials used in the process of bridge construction were mainly wood, stone, etc., and gradually the concrete, steel and other types of special materials currently in-use were developed. With the current vigorous development of science, technology and social economy in China, the development of bridge projects has also been accelerated to a large extent. In recent years, China has not only studied on how to strengthen the performance of concrete, steel and other materials in bridge projects, but also the performance of the recently developed smart, nano-, fibrous and other types of materials. This paper focuses on the application strategy of carbon fiber composite materials in bridge reconstruction projects to serve as a reference.

Composite is composed of two or more materials and its main performance is significantly different from that of each material constituting it. Each material has an appropriate quality proportion. This paper summarizes performance features of carbon fiber composite, introduces the use and development history of composite in F1 automobile race, analyzes the structural design and manufacturing process of composite in F1 racing automobile and puts forward the performance of carbon fiber composite to be improved in F1 racing automobile.

Accurately aiming and firing a pistol requires a steady hand. While many devices can steady a shooter’s arm or hand by restricting movement or degrees-of-freedom, few devices actively reduce involuntary tremors while allowing larger voluntary aiming movements. This paper details the design and fabrication of an arm exoskeleton that can actively damp arm tremors while allowing voluntary aiming movements. The device allows five degrees-of-freedom and is very lightweight due to its cable-driven architecture and use of carbon fiber composite materials. Tremorous movement is filtered out from voluntary motion, and an adaptive algorithm provides a tremor-cancelling signal to the cable control motors.
