The γ-ray co-irradiation method was employed to study the effect of diethanolamine modification on the surface of carbon fiber (CF) and the interfacial properties of CF/epoxy composites. Compared with the original carbon fiber, the surface of modified fibers became rougher. The amount of oxygen-containing functional groups was increased and the nitrogen element was detected after irradiation grafting. The interlaminar shear strength (ILSS) of composites reinforced by carbon fibers irradiated in diethanolamine solution was increased and then decreased as the irradiation dose increased. The ILSS of CF/epoxy composites was enhanced by 16.1% at 200kGy dose, compared with that of untreated one. The γ-ray irradiation grafting is expected to be a promising method for the industrialized modification of carbon fibers.

In order to understand the effect of natural environmental factors on the carbon fiber/epoxy composites, the degradation of carbon fiber/epoxy composite was studied. The specimens were exposed in a Xe lamp chamber and suffered to ultraviolet light radiation, temperature and/or humidity conditions. The results show that the radiation, temperature and/or humidity could cause extensive corrosion to the surface and interior of the carbon/epoxy composite and attack the interface between matrix and carbon fiber, resulting in an obvious reduction of the transverse tensile strength and interlaminar shear strength. On the contrary, the longitudinal transverse shear strength was not affected much by the radiation, temperature and/or humidity. The results indicate that the radiation, temperature and/or humidity can result in the corrosion of the carbon/epoxy composite and consequently affect the mechanical properties of the carbon/epoxy composite partially.

Interlaminar Shear

Interlaminar shear strength (ILSS) is an important indicator to measure the interfacial adhesion between the fiber and the matrix. The ILSS values of the unidirectional carbon fiber-reinforced epoxy composites prepared under different process conditions were investigated. Three main factors in the sample preparation, namely pressure in the molding process, fiber content of the composite, and whether to add vacuum treatment in the sample preparation process, were probed in this work. We found that the samples prepared under high pressure presented low ILSS values, but the sample prepared without pressure was not suitable for testing and the optimum pressure was 0.5 MPa. The sample prepared at lower fiber content was also not suitable for testing. However, the ILSS value decreased when the fiber content was further increased and the optimum fiber content was 60 wt%. The ILSS value was significantly increased by adding the process of vacuum treatment in the preparation.
