“…Unsaturated polyester (UP) resins are one of the most widely used types of composite resins, accounting for about 80% of all thermosetting resins. They have a good range of mechanical properties, corrosion resistance, low weight, and processibility [ 1 , 2 , 3 ], and are widely used as matrixes of composite materials for the transportation sector, building industry, and electrical industry, etc. [ 4 ].…”

Organic modified kaolinite-urea intercalation complex (KUIC) was prepared using dimethyl sulfoxide (DMSO) as the precursor of kaolinite intercalation. Its structure was characterized by Fourier transform infrared (FTIR) and X-ray diffraction (XRD). Subsequently, as a synergistic agent, KUIC was combined with flame retardant ammonium polyphosphate (APP) to improve the flame retardant and smoke suppression performance of unsaturated polyester (UP) resin. A cone calorimeter (CONE) was used to study its flame retardancy and smoke suppression, and a scanning electron microscope (SEM) and thermogravimetry (TG) were used to study the micro morphology of the char and flame retardant mechanism. The results show that 12 phr of APP and 3 phr of KUIC were doped into UP to obtain a 28.0% limiting oxygen index (LOI) value. Compared with UP, the heat release rate and smoke production of UP/APP/KUIC composites were greatly decreased. Meanwhile, KUIC indeed enhanced the mechanical properties of UP.

“…There are also reports regarding high thermally and mechanically stable hot-pressed bamboo/glass-reinforced polybenzoxazine hybrid composites which maintain good mechanical performance at elevated temperature [ 28 ]. The fact that application of carbon fiber as a reinforcing material for polybenzoxazine matrix using proper manufacturing process allows one to obtain modern, extremely durable composites that can be successfully implemented in highly demanding aerospace applications is also worth noticing [ 29 ].…”

A series of cresol-based benzoxazines were synthesized for potential application as a polymer matrix in abrasive composites. The chemical structures of the obtained benzoxazine resins were investigated in detail using Fourier transform infrared spectroscopy (FTIR) and hydrogen-1 as well as carbon-13 nuclear magnetic resonance spectroscopy (1H NMR, 13C NMR) with an additional analysis using two-dimensional NMR techniques (2D NMR 1H-1H COSY, 1H-13C gHSQC and gHMBC). Structural analysis confirmed the presence of vibrations of -O-C-N- at ~950 cm−1 wavenumber, characteristic for an oxazine ring. The thermal properties of benzoxazine monomers were examined using differential scanning calorimetry (DSC) analysis. The polymerization enthalpy varied from 143.2 J/g to 287.8 J/g. Thermal stability of cresol-based benzoxazines was determined using thermogravimetry (TGA) analysis with additional analysis of the amount of volatile organic compounds (VOC) emitted from the synthesized benzoxazines during their crosslinking by static headspace coupled with gas chromatography technique (HS-GC). The amount of residual mass significantly differed between all synthesized polybenzoxazines in the range from 8.4% to 21.2%. The total VOC emission for benzoxazines decreased by 46–77% in reference to a conventional phenolic binder. The efficiency of abrasive composites with the benzoxazine matrix was evaluated based on abrasion tests. Performed analyses confirmed successful synthesis and proper chemical structure of cresol-based benzoxazines. All the experiments indicated that benzoxazines based on different cresol isomers significantly differ from each other. Good thermal performance and stability of the abrasive composites with the polybenzoxazine matrix and significantly lower VOC emission allow us to state that benzoxazines can be a promising and valuable alternative to the phenolics and a new path for the development of modern, eco-friendly abrasives.

“…Mechanical testing of natural fiber-reinforced polymer composites is quite essential to determine its tensile strength, flexural strength, impact strength, hardness and water absorption property. Numerous studies have been carried out on mechanical testing on natural fiber-reinforced polymer composites [6][7][8][9][10][11][12]. Mechanical properties of natural fiber-reinforced polymer composites depend on various factors such as type of fiber, fiber-to-matrix ratio, stacking sequence of fiber, fiber orientation, manufacturing method and number of layers.…”

For a lot of years, extensive research was carried on the use of natural fibers in automotive sector to meet the environmental regulations as well as to increase the profit margins of company. Natural fibers being of low cost, recyclable and lightweight provide industry with the best alternative for traditional materials such as steel, aluminum and synthetic fiber. Applications such as car door panels, sun visors, seat covers and rearview mirrors have provided excellent scope for usage of natural fiber-reinforced polymer composites. Various car manufacturers have successfully implemented natural fiber-reinforced polymers in some of their car models in recent years and have yielded desirable results in terms of lightness, cost saving and reduction of environmental pollution. Various factors such as combinations of fibers, layer sequence, fiber-to-matrix ratio and manufacturing method influence the properties of the composite specimens. The natural fibers used are flax, hemp and kenaf. Epoxy is selected as a matrix material. Hand layup method was used to fabricate the specimens as well the car door panel. The mechanical testing was carried out to determine the tensile strength, flexural strength, hardness and impact strength according to ASTM standards. The composite with most desirable mechanical properties is chosen to fabricate the final car door panel. This paper also discusses about the optimization of influencing parameters for drilling the natural fiber-reinforced epoxy plate using Taguchi method. Spindle speed, feed rate and drill bit diameter are selected as input parameters. These parameters which influence the thrust force are measured by using drill tool dynamometer.
