This study explored the possibility of recycling pre-fabricated carbon to use as filler in conjunction with talc to produce glass-fiber reinforced unsaturated polyester composites. Specimens with six different resin compositions were prepared using hand lay-up technique. The structure and property relationship was characterized through tensile test and microstructure analysis. Mechanical properties incorporated with the failure analysis suggest that the recycling of carbon is feasible. The application of the recycled carbon showed the improvement on the less variation on the mechanical properties. The percent elongation at break tended to reduce, and traded-off with the deterioration on tensile strength at break and elastic modulus. Mixing with 10-15 wt% recycled carbon and 5-10 wt% talc powder was suggested to yield the optimal tensile properties. Moreover, the recycled carbon previously coated with unsaturated polyester guides the uniform distribution when required to process with a high-polarity material by reducing the polarity effect.

In this paper, the mechanical properties of glass fiber reinforced unsaturated polyester resin composite panels were investigated. To understand the effect of chopped strand mats on the mechanical properties of the composites, specimens with certain volume fraction of chopped strand mats manufactured by Vacuum Infusion Molding Process (VIMP) and Hand Lay-up techniques were tested under tensile, bending and impact loadings respectively. It was observed that the chopped strand mats enhanced effectively the mechanical properties of the composite panels manufactured by Hand Lay-up method, while the mechanical properties of the composite panels manufactured by VIMP decreased.

Abstract An experiment was carried out using glass fiber (GF) as reinforcing materials with unsaturated polyester matrix to fabricate composite by hand layup technique. Four layers of GF were impregnated by polyester resin and pressed under a load of 5 kg for 20 hours. The prepared composite samples were treated by prolonged exposure to heat for 1 hour at 60-150°C and compared with untreated GF-polyester composite. Different mechanical test of the fabricated composite were investigated. The experiment depicted significant improvement in the mechanical properties of the fabricated composite resulted from the heat treatment. The maximum tensile strength of 200.6 MPa is found for 90°C heat-treated sample. The mechanical properties of the composite do seem to be very affected negatively above 100°C. Water uptake of the composite was carried out and thermal stability of the composite was investigated by thermogravimetric analysis, and it was found that the composite is stable up to 600°C. Fourier transform infrared spectroscopy shows the characteristic bond in the composite. Finally, the excellent elevated heat resistant capacity of glass-fiber-reinforced polymeric composite shows the suitability of its application to heat exposure areas such as kitchen furniture materials, marine, and electric board.

This work represents a study to investigate the mechanical properties of longitudinal basalt/woven-glass-fiber-reinforced unsaturated polyester-resin hybrid composites. The hybridization of basalt and glass fiber enhanced the mechanical properties of hybrid composites. The unsaturated polyester resin (UP), basalt (B) and glass fibers (GF) were fabricated using the hand lay-up method in six formulations (UP, GF, B7.5/G22.5, B15/G15, B22.5/G7.5 and B) to produce the composites, respectively. This study showed that the addition of basalt to glass-fiber-reinforced unsaturated polyester resin increased its density, tensile and flexural properties. The tensile strength of the B22.5/G7.5 hybrid composites increased by 213.92 MPa compared to neat UP, which was 8.14 MPa. Scanning electron microscopy analysis was used to observe the fracture mode and fiber pullout of the hybrid composites.

Selecting materials for harsh or extreme environmental conditions can be a challenge. The combination of a harsh environment, large forces over extended periods and the need for lowest possible cost restricts the choice of materials. One potential material is glass fiber reinforced polymers that are widely used in structural systems as load bearing elements, they are relatively low cost and can be tailored to achieve a range of mechanical properties. This investigation presents the preparation of transparent glass fiber reinforced unsaturated polyester composite and the evaluation of its optical and mechanical properties under extreme conditions of temperature. The polyester resin was reinforced with E-glass fibers to manufacture a composite using the hand layup method. Transparency was achieved by modifying the refractive index of the polyester resin to match that of the glass fibers. This investigation also presents the evaluation of glass fiber reinforced unsaturated polyester under quasi-static tension loading and puncture testing using a drop weight at extreme conditions. The results showed that the reinforced composite had a higher fracture stress and chord modulus at all temperatures ranging from +60 [degree]C to -80 [degree]C as compared to the unreinforced polyester matrix. The unreinforced polyester has a higher stiffness at lower temperatures due to reduced polymer chain mobility and higher clamping pressure of the matrix on the glass fiber reinforcement. The damage created by the impact reduces with decreasing temperatures, while the energy absorb remains constant with temperature.
