“…The problem with this method is that poor adhesion of the PAn is obtained when smooth surfaces such as glass are covered. Nevertheless, this problem can be overcome by chemical grafting of the PAn to the glass surface, a procedure pioneered by Wu and coworkers9, 10 and later refined by Li and Ruckenstein 11. However, these PAn‐grafted glass fibers have not been used to prepare fiber‐reinforced composites by melt processing techniques.…”

This research was focused on the mechanical properties of electrically conducting composites based on polyaniline (PAn)-coated short glass fibers (SGFs) immersed in an isotactic polypropylene (iPP) matrix. In these composites, PAn was actually grafted onto the SGF surface, and so it was denoted PAn-g-SGF. The tensile, flexural, and interlaminar fracture toughness was investigated. To study the influence of PAn-g-SGF, three different concentrations (10, 20, and 30 wt %) were melt-mixed in the iPP resin with a batch mixer. X-ray patterns of the asmolded plaques of iPP and its composites showed an isotropic orientation. Uniaxial tensile deformation revealed that the Young's modulus and tensile stress increased as the concentration of PAn-g-SGF increased; on the other hand, the strain at failure was significantly reduced (by 2 orders of magnitude) with respect to the neat iPP. Scanning electron microscopy studies on the failure specimens indicated that the significant reduction of the strain at failure was due to the low interfacial bonding between the fibers and the surrounding matrix. Moreover, X-ray scattering analyses of the fractured regions showed that the uniaxial deformation enabled significant molecular orientation in the iPP, whereas the fractured composites remained isotropic. Detailed scanning electron microscopy analyses showed that the fracture mechanism arose from the fracture of the PAn-g-SGFs; the percolated PAn-g-SGFs formed a path for the stress transfer. Because the failure was dominated by both filler decohesion and polymeric chain rupture, the strength was not influenced significantly by the amount of PAn-g-SGFs.

“…19 Of these, interface bonding strength is the most important. Li et al 21 reported 450 C to be the optimal temperature for heat treatment, and that the residual compound oxide on the ber surface can be complete removed by heat treatment for 1 h. However, heat tends to damage and roughen the surface of the glass ber, and the resultant surface cavities on the ber surface cannot be completely lled by the resin because of its viscosity; therefore, a coupling agent is used for the anchor effect, i.e., to improve the interface properties of the composite materials. As ber and resin are two different materials with different chemical properties, the ber surface is oen coated with a layer of organic wetting agent to keep clustery for weaving in the production process.…”

We aimed to investigate the influence of different fiberglass surface pretreatments on the interfacial and mechanical properties of fiberglass-reinforced photocurable (FRP) resin pile and evaluate their cytotoxicity. The fiberglass was treated by different types, such as heat and acid treatment, and then modified by KH570, which were immersed in a laboratory-prepared photocurable resin substrate to prepare FRP resin piles. Scanning electron microscope (SEM), thermogravimetric analyses (TGA) and Fourier transform infrared spectrum (FT-IR) were used to characterize the morphologies and structures.Furthermore, the flexural modulus, bending strength, and bending load of the FRP resin piles were analyzed and the cytotoxicity on L929 cells were measured via methyl thiazol tetrazolium (MTT) assay.The results showed that high treatment could enhance the combination of the fiberglass with KH570 and then mechanical properties of the FRP resin piles, but acid treatment could reduce the performance of the FRP resin piles. MTT assay revealed the low cytotoxicity, which could be a potential application.

A method to construct glass fiber/graphene material via the electrostatic self-assembly was proposed. The graphene oxide (GO) nanosheets were firstly prepared from graphite according to Hummer's methods. Oppositely charged GO is successfully introduced to the surface of the GF cationized by 3-aminopropyltriethoxysilane (APTES) treatment in the solution with mild agitation. Sequently, glass fibers coated with graphene (GF/CRG) were obtained after chemical reduction. The graphene content was characterized by TGA and XPS tests and the value of about 0.7 wt % was obtained. Composites of poly(lactic acid) and GF/CRG were prepared through melt blending. Thermogravimetric analysis (TGA) results shows that more than 50% graphene remains on the surface of GF after processing, which indicates a strong binding between GF and graphene. GF/CRG has significant influences on crystallization and mechanical property of PLA: the crystallinity of PLA increases from 27.61 to 51.29%; the tensile strength of the PLA-GF/ CRG composite is about 63% larger than the pure PLA at the GF/CRG content of 10 wt %. This new method can apply to making composites with high performance.
