The KH-550 was modified by KH-560, and a new surfactant was got, which was used to modify nanosilicon carbide. Series of modified polyurethane elastomers (PUE) were prepared with 2,4-toluene diisosocyanate (TDI), poly (propylene glycol)(PPG-2000), modified nanosilicon carbide, carbon nanofibers and 3,3'-4,4'-dianino-diphenymethane (MOCA). The influence of different amount of filler on the mechanical properties, wear resistance of composite materials was investigated. The dispersion degree of nanofiller in matrix was analysised by SEM. The results showed that the comprehensive properties of composite had been greatly improved.

The Word composite consisting of two or more distinct materials, having two or more distinct phases with different physical properties are noticeable different from the constituent properties. Of all composite materials the fabric type has evoked the most interest among embedded in matrix materials to form laminated composites. These have been used for centuries and today industrial innovation improved energy planning. Uncertain availability and ever increasing cost have created a greater interest in composites. The engineering importance of a composite material is that two or more distinctly different materials with dissimilar characteristics combine together to form a composite that is either superior or important in some other manner to the properties of the individual materials. Most of the composites have been created to improve combinational of mechanical characteristics such stiffness, wear resistance and mechanical properties.

Mechanical And Tribological Properties

Mixtures of layered silicates (vermiculite and kaolinite) and carbon fibers were investigated as filler materials for polytetrafluoroethylene. The supramolecular structure and the tribological and mechanical properties of the resulting polymer composite materials were evaluated. The yield strength and compressive strength of the polymer increased by 55% and 60%, respectively, when a mixed filler was used, which was attributed to supramolecular reinforcement of the composites. In addition, the wear resistance increased by 850 times when using vermiculite/kaolinite fillers, which was due to protection of the surface by the formation of hard tribofilms.

Abstract Near net shape spray forming technologies have matured into viable manufacturing techniques. Spray forming can be accomplished with many different thermal spray technologies yielding a range of materials with different properties. Monolithic materials, composite materials, and multi-layer materials have all been made. Mechanical properties comparable to cast versions of the parent material are achievable for some materials and processes. Tailored properties can also be achieved for such characteristics as high hermeticity, thermal protection, electrical isolation, wear resistance, etc. A review of materials and properties is presented.

Aromatic Polyester

This study depicts the investigations of the effect of composition of aromatic polyester polyol produced from terephthalic acid (TPA) and different concentrations of monoethylene glycol (mEG) as a chain extender on the mechanical properties of polyurethane (PU) elastomer. Aromatic polyester polyols are prepared via the poly-esterification of adipic acid, terephthalic acid, catalyst, and mono ethylene glycol; while a polyurethane elastomer is formulated via the pre-polymerization of polyol with pure monomeric Methylene diphenyl diisocyanate (MDI.) Mechanical properties of polyurethane elastomers are examined, such as hardness via shore A hardness, apparent density via ASTM (American Society for Testing and Materials) D1622–08, and abrasion wear resistance via a Deutches Institut fur Normung (DIN) abrasion wear resistance tester. Structural properties are investigated through Fourier-transform infrared spectroscopy (FTIR) analysis. Results reveal that the shore A hardness of the PU elastomer increases with an increasing concentration of mEG from 4g to 12g. Nevertheless, the elastomer’s density depicts a reduction with an increasing extender content. The abrasion wear resistance of polyurethane, however, increases with an increasing concentration of glycol. A structural analysis through FTIR confirms the formation of polyurethane elastomer through the characteristic peaks demonstrated.
