Regulation of thermal relaxation behavior and aggregation structure of polyacrylonitrile fiber

open access: yesCailiao gongcheng, 2020
Polyacrylonitrile (PAN) fibers which formed high-elastic deformation during the spinning process,have thermal relaxation behavior in the heat conditions, such as thermal shrinkage with disorientation.

An Experimental Study on Mechanical Behaviors of Carbon Fiber and Microwave-Assisted Pyrolysis Recycled Carbon Fiber-Reinforced Concrete

open access: yesSustainability, 2021
In the last decade, waste carbon fiber-reinforced plastic (CFRP) products have not been properly recycled and reused, and they sometimes cause environmental problems. In this paper, the microwave-assisted pyrolysis (MAP) technology was utilized to remove

Epoxy insulated carbon fiber and carbon nanotube fiber microelectrodes

open access: yesSensors and Actuators B: Chemical, 2013
Carbon-fiber microelectrodes (CFMEs) are typically constructed from glass capillaries pulled to a fine taper or from a polyimide-coated capillary that is 90 μm in outer diameter. Here, a new fabrication method is developed to insulate carbon-fiber microelectrodes with a thin epoxy coating.

Carbon Fibers [PDF]

open access: yes, 2015
Remarkably, truly novel structures are still being found for materials made of a single element: carbon. Perhaps there is a ‘revolution’ in carbon-only materials. Indeed, recently, two Nobel prizes were awarded for new forms of carbon: for fullerenes in 1996, and for graphene in 2010.
