“…Graphene has a 2-D nanostructure and leads an enhancement in toughness of fibers [8,9]. Several researchers reported that the graphene nano material addition in the fiber reinforced composites significantly affects the mechanical [10,11], dynamic [12], thermal [13] and electrical [14] properties materials. Madhukar et al [15] stated that GnPs inclusion in unidirectional composites significantly increased the interfacial adhesion and interlaminar shear strength as well as the flexural and tensile properties.…”

Fiber reinforced polymer composite materials show several superior properties over conventional engineering materials; on the other hand, most of composite materials also have some drawbacks such as brittle behavior of matrix. This study is aimed to improve the impact response of composite material by adding nano particle into epoxy matrix. For this purpose; an experimental study was conducted to investigate the effect of graphene nano particles inclusion in epoxy resin with glass fiber reinforced composite plate on the Charpy impact response. Glass fiber reinforced (GFR) epoxy composite plates were produced with various graphene nano platelets content such 0, 0.1, 0.25 and 0.5 wt%. Low velocity impact response was investigated by using Charpy impact test method. Impact energy and impact damage results presented in detail.

“…From the above analysis, it can be concluded that GOs/CF satisfies the requirements of CF handling characteristics during subsequent textile processing. The mechanism of the improvement of GO/CF-EP ILSS might be related to the increase of the wettability between CF and matrix [20,35,36]. The different phenomena can be explained through the interfacial microstructure, and chemical bonding between GO sheets and matrix resin.…”

The graphene oxide (GO) sheets with different size distributions were effectively separated by a centrifugation method. The exfoliated single-layer structure and the size of GO sheets were verified by scanning electron microscopy (SEM), atomic force microscope (AFM), and metallurgical microscope, respectively. Two different-sized GO sheets water suspensions were obtained, which were then directly dispersed in carbon fiber (CF) sizing agent, respectively. The influences of the different-sized GO sheets on CF and CF composites were explored. The workability in later process of CF and CF surface morphology were characterized by abrasion resistance, fluffs and breakage, stiffness, and SEM. SEM micrographs demonstrated that a nonuniform distribution of the large-sized GO was lapped on CF whereas the small-sized GO was uniformly leaned on CF. The interlaminar shear strength of the smallsized GO/CF reinforced composite could reaches the maximum value. It indicated that the interfacial region between CF and polymer matrix could be enhanced by adjusting the size of GO sheets. POLYM. COMPOS., 00:000-000, 2015. V C 2015 Society of Plastics Engineers INTRODUCTIONCarbon fiber (CF) composites have been used as structural materials and applied to replace many metals in various applications, such as the aircraft, rocket, sport, military industries, and other transport vehicles, because of their excellent mechanical and thermal stability, higher strengthto-weight ratio property [1][2][3][4][5]. It is well-known that the property of CF composites is, to a large extent, dependent on the bonding situation of fiber-matrix interface. Good interfacial property is necessary to guarantee efficient load transfer from matrix to fillers, which helps to improve mechanical properties. The problem of CF composites, however, is that it shows poor interfacial property between CF and polymer matrix [6]. Therefore, nowadays many professionals carry out extensive researches on improving the interfacial property of CF composites [7][8][9][10].Graphene, a single-atom-thick sheet of hexagonally arrayed sp 2 -bonded carbon atoms, exhibits numerous unique properties [11]. In recent years, graphene and graphenebased materials have attracted tremendous attention because of their exceptional chemical, optical, electronic, and mechanical properties, which demonstrate a huge potential for various applications, such as transparent electrodes, super capacitors, and composites [12][13][14]. Graphene oxide (GO) sheets, an oxidized shape and intermediate in synthesis of graphene, have good handling characteristics and chemical reactivity in solution due to the intrinsic functional groups [15][16][17]. GO sheets were synthesized by a modified Hummers method normally [18,19].Zhang et al. [20] have prepared a stable GO-modified CF sizing agent by directly dispersing GO sheets in CF sizing agent. It had demonstrated that the addition of GO in the sizing agent could improve the interfacial properties of composites and it was more effective than the method of dispersin...

“…have been successfully used to fabricate automobile parts, window materials, gardening irrigation equipment, and other electronic apparatuses. [1][2][3][4] However, in extreme conditions that require high mechanical properties and excellent conductivity, ASA composites still do not meet the demand. Consequently, it is necessary to improve ASA materials by physical or chemical methods.…”

The aim of this study was to improve the mechanical properties of an acrylonitrile-styrene-acrylate copolymer (ASA) with the help of carbon fibers (CFs). Additionally, the effects of the CFs on the morphology, rheological properties, dynamical mechanical properties, electrical resistivity, and heat resistance of the ASA composites were studied with scanning electron microscopy, rotational rheometry, and dynamic thermomechanical analysis (DMA). The mechanical properties of the ASA composites were enhanced largely by the CFs. The maximum tensile strength of the ASA/CF composites reached 107.2 MPa. The flexural strength and flexural modulus also reached 162.7 MPa and 12.4 GPa, respectively. These findings were better than those of neat ASA; this was attributed to the excellent interfacial adhesion between the CFs and ASA resin. Rheological experiments proved that the viscosity and storage modulus (G 0 ) values of the ASA/CF composites did not increase until the CF content reached 20%. The DMA outcomes confirmed that the glass-transition temperature of the ASA composites was elevated from 120.6 to 1258C. Importantly, the G 0 values of the composites with 20 and 30% CFs showed a large increase during heating. In addition, the ASA/CF composites exhibited excellent conductivity and heat resistance.
