Structural Applications

New technologies in the automotive industry require lightweight, environment-friendly, and mechanically strong materials. Bast fibers such as kenaf, flax, and hemp reinforced polymers are frequently used composites in semi-structural applications in industry. However, the low mechanical properties of bast fibers limit the applications of these composites in structural applications. The work presented here aims to enhance the mechanical property profile of bast fiber reinforced acrylic-based polyester resin composites by hybridization with basalt fibers. The hybridization was studied in three resin forms, solution, dispersion, and a mixture of solution and dispersion resin forms. The composites were prepared by established processing methods such as carding, resin impregnation, and compression molding. The composites were characterized for their mechanical (tensile, flexural, and Charpy impact strength), thermal, and morphological properties. The mechanical performance of hybrid bast/basalt fiber composites was significantly improved compared to their respective bast fiber composites. For hybrid composites, the specific flexural modulus and strength were on an average about 21 and 19% higher, specific tensile modulus and strength about 31 and 16% higher, respectively, and the specific impact energy was 13% higher than bast fiber reinforced composites. The statistical significance of the results was analyzed using one-way analysis of variance.

In order to study the influences of the contents of short fiber on the mechanical properties of concrete matrix, the properties of compressive, flexure and splitting of concrete matrix reinforced by alkali resistant glass fiber and calcium carbonate whisker were tested. To study the reinforced effect of different scale fibers on the flexure behavior of fine concrete sheets, the flexural tests of concrete sheet of fine concrete reinforced with basalt fiber mesh and short fiber composites were carried out. The results show that the properties of the compressive, flexure and splitting of fine concrete reinforced with appropriate amount of alkali resistant glass fiber and carbonate whisker are improved compared with that of concrete reinforced by one type of fiber. The flexure properties of the concrete sheets are improved obviously when continuous fiber textile and short fiber composite are adopted to reinforce.

AbstractA new type of material was prepared by modifying epoxy/basalt fiber composites with nanoSiO2. Mechanical tests showed that the nanoSiO2-modified epoxy/basalt fiber composites displayed significant improvement over the unmodified epoxy/basalt fiber composites in interlaminar shear strength and notch impact strength. Scanning electron microscopy revealed that the nanoSiO2was homogeneously dispersed in the epoxy matrix and adsorbed large numbers of epoxy molecules onto the surface. Many of the nanoSiO2-epoxy complexes tightly surrounded basalt fibers to form transition layers. Therefore, nanoSiO2can act as a nano-mediator to promote epoxy molecules to infiltrate between and bind to basalt fibers, which enhances the synergistic cooperation between epoxy and basalt fibers in resisting external forces. This study indicates that modification with nanoSiO2is an effective pathway to improve the performance of epoxy/basalt fiber composites and broaden their application fields.

New Type

Open circular holes with a certain size in beam web at 1/6 span is a new method to improve the seismic behavior of steel moment frames. Based on the results of elasticity theory, analytical model of frame with opening web is proposed, and analysis and verification with nonlinear finite element method (FEM) are conducted. Results show that, beam with opening web at 1/6 span can significantly reduce the axial stress of beam flange near the beam-column connections. It is helpful to achieve the design criterion of strong connection and weak member, and also to simplify the connection construction. If the diameter of web opening is appropriate, beam plastic hinges can move inward to beam section at opening web, and has little effect on bearing capacity, stiffness, energy dissipation capacity and ductility of frames. The method of web openings and the size range are presented at the end of this paper.
