“…Figure 8 shows the effect of chain lengths on IFSS of CF/PAA composites. [26,27] As shown, chain lengths have significant influence on the interfacial adhesion in composites. The IFSS of untreated one is much lower than those treated ones, and it appears that longer the chain lengths on fiber surface are, higher the values of IFSS are.…”

The influence of chain lengths on interfacial performances of carbon fiber/polyarylacetylene composites was studied. For this purpose, four coupling agents, methyltrimethoxysilane, propyltrimethoxysilane, octyltrimethoxysilane and dodecyltrimethoxysilane, were grafted onto fiber surface to obtain different chain lengths. The resulting carbon fiber surface was characterized by XPS and dynamic contact angle test. Interfacial adhesion in the resulting fiber reinforced polyarylacetylene resin composites was also evaluated by fracture morphology analysis and interfacial shear strength test. It was found that the interfacial adhesion in composites greatly increased with chain lengths on fiber surface. The improvement of interfacial adhesion was attributed to the interaction between the chain of coupling agents on fiber surface and that of polyarylacetylene resin at the interface.

“…However, before using carbon fiber to reinforce a matrix, its surface must be treated, because it is inert and smooth (2,3). This treatment is the decisive factor in improving the interfacial adhesion properties between carbon fiber and a matrix (4).…”

Grafting hyperbranched polyglycerols onto a carbon fiber surface is done in an attempt to improve the interfacial and impact properties between carbon fiber and epoxy resin. Scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS) and dynamic contact angle analysis were performed to characterize the carbon fibers. The TGA result shows that the mass fraction of the hyperbranched polyglycerols grafted onto the carbon fibers surface was 9.03%. The SEM results indicate that the hyperbranched polyglycerols have been grafted onto the carbon surface and that the surface roughness of the carbon fiber significantly increased. The XPS result indicates that oxygen-containing functional groups obviously increased after modification. Dynamic contact angle analysis indicates that the surface energy of modified carbon fibers increased significantly compared with the untreated ones. Results of the mechanical property tests show that interfacial shear strength increased from 59.86 to 80.16 MPa, interlaminar shear strength increased from 57.57 to 73.49 MPa and impact strength simultaneously increased from 2.52 to 3.52 J.
