“…Hexagonal boron nitride has a lamellar crystalline structure in which the bond between molecules within each layer is strong covalent, while the binding between layers is almost entirely maintained by means of weak van der Waals forces. This structure is similar to that of graphite and molybdenum disulfide (MoS 2 ), which are highly successful solid lubricants, and the mechanism behind their effective lubrication performance is understood owing to easy shearing along the basal plane of the hexagonal crystalline structures [19][20][21][22][23]. Besides, heat resistant of h-BN would also have complicated effects on the tribological properties of PTFE/ PHBA composites.…”

“…Improvement in the tribological properties of the phenolic resin enhances the wear and aerodynamic shear resistance of the phenol based carbon composites [30]. Yi and Yan studied the mechanical and tribological properties of phenolic composite dispersed with several inorganic fillers like calcined petroleum coke (CPC), talcum powder (TP), and hexagonal boron nitride (h-BN) [31]. The phenol based composite with 10% h-BN shows excellent friction stability and wear resistance at various testing conditions beyond 125 ∘ C and results in formation of compact friction film on the rubbing surface of composite.…”

Composite materials have been steadily substituting metals and alloys due to their better thermomechanical properties. The successful application of composite materials for high temperature zones in aerospace applications has resulted in extensive exploration of cost effective ablative materials. High temperature heat shielding to body, be it external or internal, has become essential in the space vehicles. The heat shielding primarily protects the substrate material from external kinetic heating and the internal insulation protects the subsystems and helps to keep coefficient of thermal expansion low. The external temperature due to kinetic heating may increase to about maximum of 500 ∘ C for hypersonic reentry space vehicles while the combustion chamber temperatures in case of rocket and missile engines range between 2000 ∘ C and 3000 ∘ C. Composite materials of which carbon-carbon composites or the carbon allotropes are the most preferred material for heat shielding applications due to their exceptional chemical and thermal resistance.

“…The major drawbacks of the PF resins which prevents its widespread applications are high brittleness and shrinkage. This properties are surmounted by inclusion of micron sized particulate fillers and load bearing synthetic fibers or elastomeric materials [6][7][8][9][10][11]. PF resin generates chemical bonding with synthetic fibers/surface modified fillers, leading to strong forces between fiber/particulate and resin.…”

Abstract. Mechanical properties of phenol formaldehyde (PF) based hybrid composites reinforced with molybdenum disulphide (molykote; MC), copper (Cu), graphite (Gr) and antimony (Aty) particles in micron size, having different shape and aspect ratio, are studied. Incorporation of MC, Cu and Gr enhanced the hardness, compression and flexural properties of PF based hybrid composites. A slight decrease in density was observed in MC + Gr (A5) reinforced PF based hybrid composites, making these composites suitable in weight susceptible applications. The investigations showed that the control sample A1 without MC/Cu/Gr/antimony (control sample) exhibited poorer mechanical properties. Addition of Cu, MC and Gr to the control sample resulted in moderate improvement in the mechanical properties. However, hybridization of the control sample with Gr + Aty (A6) showed lower mechanical properties compared to that of composites filled with MC and Gr (A4 and A2) respectively. This decrease was ascribed to the tendency of non-uniform dispersion, deprived bonding of Aty particles as well as poor filler-matrix adhesion. When Aty was replaced with Gr + MC (Sample A5), filler-filler with matrix interaction appears to be increased, resulting in increased strength and modulus. The developed PF based hybrid composites have exhibited improved mechanical properties and these composites with detailed thermal and tribostudies may be recommended for railway braking applications.
