Effect of potassium titanate whiskers on the mechanical and tribological properties of glass/epoxy composite systems has been investigated experimentally. Composite laminates were prepared by hand lay-up technique followed by vacuum bagging by varying the percentage of potassium titanate whiskers addition. Mechanical properties of the developed composites were evaluated as per ASTM standards. Tribological tests were conducted under dry sliding conditions on a pin on disc test rig. The tests results indicated that addition of the potassium titanate whiskers has significant effect on the properties of glass/epoxy composites. Density, hardness, stiffness properties, friction coefficient and wear resistance of the composites were found to improve with the potassium titanate whiskers loading. However, strength properties of the glass epoxy composites were found to reduce with whisker content. The mode of failure after the tensile tests and worn surface of some selected samples were studied using scanning electron microscope.

“…Epoxy resins are one of the extensively used thermosetting resins. It is mostly used in the form of coatings and structural adhesives for many engineering applications in addition to its usage as matrices for fibre reinforced composites due to its superior thermal and mechanical properties, excellent corrosion and chemical resistance [10]. Hameed et al [11] conducted a study on the utilisation of the modified epoxy resin as matrix in glass fibre composites.…”

Abstract. Glass fibres have the principal advantages such as high tensile strength, high chemical resistance, low cost, and excellent insulating properties which makes them an important constituent in fibre reinforced plastic and composite industry. In this study, E-glass fibre in the form of Chopped Strand Mat (CSM) with different weight fractions such as 15%, 30%, and 45% were used as reinforcement in CNSL-epoxy resin composites. Fabrication of the composites was done by hand layup technique. Micro-hardness, tensile and flexural properties were investigated for all the composite panels of different compositions. The results clearly indicated an improvement in micro hardness, tensile and flexural properties with the increase in fibre content.

In general, epoxy resin (EP) glue mixed with a high content of flame retardants is used to coat glass fabrics layer by layer to prepare fire‐retardant printed circuit boards (PCBs). However, the addition of the flame retardants not only increases the cost but also greatly deteriorates the processability and mechanical properties of the PCBs. In this study, a gradient distribution mode of composite flame retardants was designed and applied in EP‐based PCB composites. Unlike the traditional uniform distribution mode, in which flame retardants are evenly distributed in every resin layer, the gradient mode concentrates a higher content of the flame retardants on the surface layer, and the concentrations are gradually reduced along the thickness. In this way, the surface resin can quickly form a condensed charring barrier to hold back fire; this effectively protects the underlying resin, which has lower contents of flame retardant. The results of this study show that PCB prepared by the gradient mode obtained satisfactory flame retardance (a UL94 V‐0 rating) with only a 3.5 wt % total amount of flame retardant; this value was much lower than that (6.3 wt %) of composites featuring a uniform distribution. Additionally, the gradient mode also maintained the mechanical properties of PCB better. The tensile, impact, and flexural strengths of the gradient distribution system were obviously higher than those of the uniform distribution one with the same content of flame retardant. On the basis of the mode, a more economic and efficient technology was developed to manufacture flame‐retardant layered PCB. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44369.
