چکیده
The paper describes the modification conducted for PAN carbon fiber surfaces in solutions of nitric and sulphuric acids. authors studied impact parameters such as temperature, acid concentration, time ratio nitrosulphuric on occurrence reactive groups surface. revealed presence carboxylic ketone range 1663-1798 1568 cm -1 IR spectra fibers. use did not identify sulfur-containing functional spectra. Preliminary treatment surface led to formation uniform continuous coating a SiO 2 barrier being 127 ± 30 μm by sol-gel method.

Effect of Fiber Surface Treatment on Wear Characteristics of Carbon Fiber Reinforced Polyamide 6 Composites
Ozone modification method and air-oxidation were used for the surface treatment of polyacrylonitrile(PAN)-based carbon fiber. The surface characteristics of carbon fibers were characterized by X-ray photoelectron spectroscopy (XPS). The interfacial properties of carbon fiber reinforced polyamide 6 (CF/PA6) composites were investigated by means of the single fiber pull-out tests. As a result...

متن کاملEffect of surface treatments on damping behavior of carbon and glass fiber reinforced friction material
The ability to absorb vibrations in a vehicle during braking conditions depends primarily on the selection of ingredients for a friction material and interfacial adhesion between all these ingredients. In this work, a hybrid brake friction material is developed by combination of carbon fiber (CF), glass fiber (GF), resin and other ingredients. The surfaces of carbon and glass fibers are c...
متن کاملA Procedure for Preparation of Semi-activated Carbon Fiber without any Treatment under High Temperature
A procedure for preparation of semi-activated carbon fiber (SACF) without any treatment under high temperature was proposed. The first step of the procedure is coating of an inorganic fiber (E-glass fiber) by an adsorbent mixture including powder activated carbon, methyl cellulose and water. In this work a set of experiments was performed to attain appropriate adsorbent mixture for good quality...
متن کاملEdge effect of a carbon fiber meeting a surface
This paper investigates the free edge effect on the stress field of a carbon fiber, which is embedded into an epoxy matrix. The fiber is assumed to possess cylindrical symmetry and to be transversely isotropic. The matrix is assumed to be of an isotropic material. The stress field is induced by a uniform tension applied on the matrix at points far away from the fiber surface. The displacement a...
