“…They have also attracted a longstanding attention [1][2][3][4][5]. However, epoxy resins are inherently brittle and hence have reduced damage tolerance, and consequently the damage tolerance of the epoxy composites.…”

Abstract. Carbon fibers chemically grafted with hydroxyl-terminated diblock copolymer poly (n-butylacrylate)-b-poly (glycidyl methacrylate) (OH-PnBA-b-PGMA), were used as the reinforcement for epoxy composites. The multi-filament composite specimens were prepared and measured by dynamic mechanical analysis (DMA), to study the interfacial toughness of carbon fiber reinforced epoxy composites with the diblock copolymers. The loss modulus and loss factor peaks of !-relaxation indicated that composites with diblock copolymers could dissipate more energy at small strain and possess better interfacial toughness, whereas composites without the ductile block PnBA having the worse interfacial toughness. The glass transition temperature and the apparent activation energy calculated from the glass transition showed that the strong interfacial adhesion existed in the composites with diblock copolymers, corresponding with the value of interfacial shear strength. Therefore, a strengthening and toughening interfacial structure in carbon fiber/epoxy composites was achieved by introducing the diblock copolymer OH-PnBA-b-PGMA. The resulting impact toughness, characterized with an Izod impact tester, was better than that of composite without the ductile block PnBA.

“…Both types of these composites have high strength-to-weight ratio and excellent fatigue strength [3], high corrosion resistance so that the material is so widely used in the fields of aerospace and automotive industries [4,5,6]. Mechanical properties and GFRPs CFRPs with epoxy-reinforced not only depend on the intrinsic characteristics of CFRPs and GFRPs of the epoxy resin, but also by the interfacial interactions in the CFRPs and GFRPs / epoxy interphase [7,8]. Fiber-matrix adhesion is one of the key parameters for the mechanical properties of carbon fiber and glass reinforced polymer [9].…”

“…Carbon fiber (CF) reinforced polymer composites have been widely used in aerospace, automobiles, constructions and other industry fields because of their excellent mechanical properties, such as high specific strength, specific modulus and damping capacity [1][2][3]. As well known, the mechanical properties of fiber reinforced composites are largely dominated by the fiber-matrix interfacial adhesion.…”

Abstract. Maleic anhydride functionalized graphene oxide (MAH-GO) was synthesized and then introduced into carbon fiber (CF) reinforced bismaleimide (BMI) composites, with the aim of improving the interfacial adhesion strength between CF and BMI resin. Various characterization techniques including Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectra (XPS) and thermogravimetric analysis (TGA) demonstrated that the maleic anhydride has been successfully grafted onto the GO surfaces. The study showed that the interlaminar shear strength (ILSS) and flexural properties of CF/BMI composites were all improved by the incorporation of GO and MAH-GO, and the MAH-GO showed the substantially improved effect due to the strong interaction between the MAH-GO and the resin matrix. The maximum increment of the ILSS, flexural strength and flexural modulus of composites were 24.4, 28.7 and 49.7%, respectively. Scanning electron microscope (SEM) photographs of the fracture surfaces revealed that the interfacial bonding between CF and resin matrix was significantly strengthened by the addition of MAH-GO. The results suggest that this feasible method may be an ideal substitute for the traditional method in the interfacial modification of composites.
