AbstractSeveral glass systems based on AIF3 have been synthesized and fabricated into preforms by controlled melting and rotational casting. High optical quality preforms have been drawn into fibers using a specially modified drawing facility. The drawing tower is enclosed with a vertical glove box in which the levels of both moisture and oxygen are kept below 1 ppm during the drawing. The AIF3 -based fibers have shown dramatically superior chemical durability relative to the ZrF4 -based glass fibers. Selected optical, mechanical and thermal properties of these fibers will be presented. AIF3 -based glass fibers offer interesting opportunities for short range applications in the 2–4 micron region of the infrared such as sensing, remote spectroscopy and laser power delivery.

The investigation and design of new polymeric materials with an astonishing combination of properties are nowadays of great importance to facilitate the manufacturing process of high-quality products intended to be utilized in different applications and technical fields. For this intent, novel high-performance blend composites composed of the cyanate ester/benzoxazine resin blend reinforced by different proportions of silane-surface modified Kevlar and glass fibers were successfully fabricated by a compression molding technique and characterized by different experimental tests. The mechanical test results revealed that the bending and impact strength properties were considerably improved when increasing the amount of the hybrid fibers. The studied materials also presented excellent thermal stabilities as compared to the unfilled blend’s properties. With respect to the properties of the reinforcing systems, these improvements seen in either the mechanical or thermal properties could be due to the good dispersion as well as excellent adhesion of the reinforcing fibers inside the resin matrix, which were further evidenced by the Fourier transform infrared spectroscopy and scanning electron microscopy results. Consequently, the improved mechanical and thermal properties promote the use of the fabricated hybrid composites in domestic and industrial applications requiring functional materials with advanced properties for aerospace and military applications.

Basalt Fibers

Natural fibers, such as kenaf, hemp, and flax, also known as bast fibers, offer several benefits such as low density, carbon dioxide neutrality, and less dependence on petroleum sources. Their function as reinforcement in polymer composites offers a great potential to replace a segment of the glass fiber-reinforced polymer composites, especially in automotive components. Despite their promising benefits, they cannot meet the structural and durability demands of automobile parts because of their poor mechanical properties compared to glass fibers. The focus of this research work was the improvement of the mechanical property profile of the bast fiber reinforced polypropylene composites by hybridization with natural high-performance basalt fibers and the influence of basalt fibers coating and polymer modification at the mechanical and thermal properties of the composites. The specific tensile strength of the composite with polymer tailored coating was 39% and the flexural strength was 44% higher than the composite with epoxy-based basalt fibers. The mechanical performance was even better when the bast/basalt hybridization was done in maleic anhydride modified polymer. This led to the conclusion that basalt fibers sizing and polymer modification are the deciding factors in defining the optimal mechanical performance of the composites by influencing the fiber-matrix interaction. The composites were analyzed for their mechanical, thermal, and morphological properties. The comparison of bast/basalt hybrid composite with bast/glass fibers hybrid composite showed a 32% higher specific flexural and tensile strength of the basalt hybrid composite, supporting the concept of basalt fibers as a natural alternative of the glass fibers.

The rising concern towards environmental issues and lower production costs has led to increasing interests on the use of natural fibers to replace glass fibers as reinforcements. In this paper, the mechanical and physical properties of natural fiber composites and their hybrids or sandwiches were investigated. Jute woven fabric composites and their sandwiches were produced by applying vacuum assisted resin transfer molding (VARTM). For the composite sandwiches, glass woven composites were placed at the outer surfaces of jute woven composites and could act as strong skins. Therefore, the bending properties of jute-glass woven composites are higher than those of jute woven composites. The thin glass woven composites at the outer layer of composite sandwich also reduce the rate of water absorbed by the composites. The water absorption in jute-glass woven composites is lower than those in jute woven composites. Nano fillers that were added into the composites were expected to improve the mechanical and thermal properties of the composites. So far, matrices with 1 wt% of nano fillers have been successfully infused into fibers through VARTM process. The thermal properties of glass woven composites with nano fillers are significantly increased. However, the addition of nano fillers in jute fiber composites does not increase their thermal properties as the decomposition of the natural fiber occurs at the temperature whereby the epoxy matrix starts to degrade.

Effects of curing temperature on glass fiber/urethane composite’s mechanical and thermal properties were investigated in this paper. L100 and curing agent C3 were mixed sufficiently with the mass ratio of 100:15 at the temperature of about 50°C, and 3 layers of glass fibers with the size of 10cm×30cm (the thickness of each layer is 0.2mm) were prepared. Then glass fabric/L100 polyurethane composites were fabricated by vacuum-assisted hand lay-up process at the temperature of 150°C, 160°C and 170°C, respectively. As the resin system is used in pultrusion process which demands the resin system can cure adequately within 5min to 15 min. The isothermal differential scanning calorimetry (DSC) method was used to investigate the curing time at the above three temperatures to testify whether the resin system can cure during a short span of time to meet the requirement. The results demonstrate that L100/C3 resin system cures within 8-10min at the temperature of 150°C and 160°C, while under 170°C, the resin system cures fully within 5min,which clearly show that the resin system meet the basic requirement of fast process. In order to better analyze the effect of curing temperature on sample’s mechanical properties, corresponding mechanical tests were conducted. The tension tests demonstrate that the tensile strength and elongation at break reduce with the rise of curing temperature. The interface strength test and field emission scanning electron microscope photography were conducted. The results show that higher curing temperature leads to lower interface strength. The decrease of the interface strength is due to the different reactivity of three reactive groups in L100. With the rising of temperature, reactivity groups tend to react with curing agent C3, but not to combine with coupling in the surface of glass fiber, hence weakens the link between resin and fiber. This assumption can be confirmed by the DSC tests, which show that curing temperatures have little effects on glass transition temperature of the samples. Additionally, the infrared spectra of the composites cured at the above three different temperatures indicate that curing temperatures exert no significant influence on the composition of the composites. Based on the above results, 150°C is chosen to be the optimal curing temperature for the glass fabric/L100 polyurethane composites.
