Plastic Products

The recycling of plastic products is gaining widespread attention because of its significance in the reduction of petroleum consumption and in the conservation of limited resources. It is also an effective method of handling plastic waste, as opposed to traditional landfill and incineration waste disposal methods. This study attempts to find a method by which to manage the increasing amount of PA66-GF waste generated by the gear industry through the recycling method. By adopting the L27 Taguchi orthogonal array, S/N ratio and ANOVA are conducted to evaluate the impact of recycled materials on various compositions. The different settings of injection parameters on the gears’ Young’s modulus and elongation at break are also identified and examined.

Two Factors

The object of this work is to study and predict the tensile properties (tensile strength, elastic modulus, and elongation at break) of ternary nanocomposites based on epoxy/glass fiber/nanosilica using the fuzzy logic (FL). Two factors in three levels including glass fiber at 0, 5, and 10 wt% and nanosilica at 0, 0.5, and 1 wt% were chosen for adding to an epoxy matrix. From FL surfaces, it was found that the glass fiber content had a main role in the tensile properties of nanocomposites. The high levels of glass fiber content led to a significant increase in the elastic modulus and generally, the presence of glass fiber decreased the tensile strength and elongation at break. Also, addition of the nanosilica content resulted in an increased elastic modulus but decreased the elongation at break of nanocomposites. Finally, an FL model was obtained for each tensile property.

Chrysanthemum flowers are usually used for cultural and religious ceremonies however, the chrysanthemum stems are left for open burning or landfilling on many farmlands. These stems are one of the sources of agricultural waste in Malaysia that cause environmental impacts. In order to reduce the impact of chrysanthemum stems, this research study has utilised these valuable chrysanthemum stems in producing a new polymer composite. Hence, the present research study focuses on the preparation of non-woven and woven chrysanthemum stem fibre (CSF) reinforced unsaturated polyester (UPs) composites via simple hand lay-up method. The results showed the tensile properties (tensile strength and modulus of elasticity) of woven fibre filled UPs was higher than non-woven fibre filled UPs composites. However, non-woven fibre filled UPs presented higher water absorption and elongation at break as compared to woven fibre filled UPs composites. Furthermore, bleaching treatment with hydrogen peroxide is carried out in order to improve the tensile properties and water resistance of UPs/CSF composites. The functional groups of unbleached and bleached fibres were analysed using Fourier Transform Infrared (FTIR) analysis. Some lignin, hemicellulose and impurities of CSF have been removed after the bleaching treatment on CSF, as proven by FTIR results.

Air quality control has become increasingly important in many industrial areas. Glass fiber filter paper is widely used for the collection of airborne particulate matter. Since glass fiber is fragile, fiber dispersion is believed to be important for controlling filter paper properties. In this paper, the impact of fiber dispersion on filtration performance and tensile properties was studied. Two types of glass fiber filter paper prepared from six different dispersing methods were used to analyze the impact of dispersion on filtration and tensile properties. Rotational viscosity was used to characterize the fiber dispersion process. Dispersing strength and time had no significant effect on filtration properties, namely the pressure drop, penetration and figure of merit. The fiber composition should be the determining factor of filtration properties. Dispersing strength and time had little effect on the virgin tensile strength of glass fiber paper, while the tensile strength retention after folding was highly affected by dispersion. It is suggested that fiber cutting should be reduced in the fiber dispersion process for higher tensile strength retention.

Loss Of Strength

Polytetrafluoroethylene (PTFE)-coated glass fiber fabrics are used for long-lasting membrane structures due to their outstanding mechanical properties, chemical stabilities, and satisfying service life. During their operation time, different environmental impacts might influence their performance, especially regarding the mechanical properties. In this contribution, the impact of water on the tensile strength deterioration was assessed experimentally, providing evidence of considerable but partially reversible loss of strength by up to 20% among the various types of investigated industrially established fabrics.

The Impact

This study analyzes the fundamental principles and characteristics of the microcellular foaming process (MCP) to minimize warpage in glass fiber reinforced polymer (GFRP), which is typically worse than that of a solid polymer. In order to confirm the tendency for warpage and the improvement of this phenomenon according to the glass fiber content (GFC), two factors associated with the reduction of the shrinkage difference and the non-directionalized fiber orientation were set as variables. The shrinkage was measured in the flow direction and transverse direction, and it was confirmed that the shrinkage difference between these two directions is the cause of warpage of GFRP specimens. In addition, by applying the MCP to injection molding, it was confirmed that warpage was improved by reducing the shrinkage difference. To further confirm these results, the effects of cell formation on shrinkage and fiber orientation were investigated using scanning electron microscopy, micro-CT observation, and cell morphology analysis. The micro-CT observations revealed that the fiber orientation was non-directional for the MCP. Moreover, it was determined that the mechanical and thermal properties were improved, based on measurements of the impact strength, tensile strength, flexural strength, and deflection temperature for the MCP.

In this article, the response of 12 plain concrete specimens to an impact of hard projectiles was examined in an experimental study. The tests were planned with an aim to observe the influence of using glass fiber reinforced polymer sheets to strengthen plain concrete panels on the performance of concrete under this type of loading. The main findings show that strengthening plain concrete panels with glass fiber reinforced polymer sheets showed satisfactory performance under the impact load; the glass fiber reinforced polymer sheets can be used for strengthening or upgrading concrete structures to improve their resistance against impact. Also, the location of the glass fiber reinforced polymer sheet affects the front and rear face craters.

The performance of a composite material system depends critically on the interfacial characteristics of the reinforcement and the matrix material. In this study, the interfacial adhesion was tailored by the creation of textures on the glass fiber surface using inorganic-organic silane blends. A single-fiber microdroplet test was conducted to assess the interfacial properties between the textured glass surface and an epoxy matrix. The load–displacement curves from microdroplet tests were analyzed. The stress-based and energy-based micromechanic models of interfacial debonding and corresponding adhesional parameters (apparent and ultimate interfacial shear strength, friction stress, critical energy release rate, work of adhesion, and adhesional pressure) were applied for theoretical calculations. The results showed a clear trend for the impact of different silane blends on the interfacial properties. The specimens containing 75:25 and 50:50 of inorganic–organic silane blends show the most effective improvement in the interfacial adhesion properties between glass fiber and epoxy resin. Scanning electron microscopy was used to visualize the failure surface of the specimen after the microdroplet test. The scanning electron microscopic images indicated that the failure in the blend sized treated glass fiber–epoxy matrix specimen runs predominantly along the interphase and combines both cohesive failure in resin (the presence of some resin fragments) and adhesive failure (some bare fiber surfaces can be seen).
