“…Researchers have done much work on sizing CF for reinforcing thermoplastic resins 14–17 . Karsli et al revealed that polyurethan or polyamide as sizing agent of CF for reinforcing polyamide 66 (PA66) matrix possessed higher interfacial adhesion than other sizing materials, and tensile strength of the composites was enhanced by about 18% compared with that with unsized CF 18 .…”

The interfacial adhesion character highly depends on interactions of the interfacial molecules. Carbon fiber (CF) is sized by in situ polymerization of maleic acid and glycerol to form a hyperbranched polyester (HBPE) layer on the surface in an environmental and efficient technique. Vast hydroxyl groups are introduced to the CF surface with the presence of HBPE. Moreover, the HBPE sizing structure on 6 A/m2 moderately oxidized CF surface presents higher branch extent and more terminal hydroxyl groups than that on unoxidized or over‐oxidized CF surface. The interlaminar shear strength of polyamide 66 composite reinforced with HBPE sized oxidized‐CF under 6 A/m2 current density is optimal and remarkably enhanced to 77.9 MPa by 46% compared to that with the unsized one. The significant interfacial property improvement is attributed to the abundant terminal hydroxyl groups on HBPE sizing structure, which enhances the interaction at the interface of CF/sizing and sizing/matrix by constructing many covalent and hydrogen bonds.

A time-dependent oxidation of carbon fibers in boiling nitric acid was used to investigate the influence of a modification of the fiber surface properties on the adhesion strength with an acrylate resin cured by electron beam (EB). For each time of treatment, a characterization of the surface topography and the surface chemistry was done (topography at a micrometric and nanometric scale, specific surface area, temperature programmed desorption, X-ray photoelectron spectroscopy analysis). The oxidation of the fiber surface in boiling nitric acid created a rough surface, which significantly increased the specific surface area, and also generated a high density of hydroxyl groups, carboxylic acids and lactones in comparison to untreated fibers. The adhesion strength with the acrylate resin cured by EB was measured by a pull-out test. For comparison, an isothermal ultraviolet curing of the matrix was also investigated. The value of the interfacial shear strength, determined by the Greszczuk's model, was increased by the oxidation of the carbon fiber surface for both curing processes, but lower values were systemically obtained with EB curing.

ABSTRACT:In a reaction between 2-hydroxyethyl methacrylate and phenyl isocyanate (PI), we did not obtain the expected urethane ester monomer but products of its subsequent conversion, namely, ethylene dimethacrylate and ethylene bis(phenylcarbamate). The effects of the structures of various hydroxyalkyl esters on the transformation of the products of their reaction with PI into their respective diesters and alkanediyl bis(phenylcarbamates) were observed with standard spectral methods (IR, 1 H-NMR) and chromatographic and classical separation techniques.
