Advanced Composite Materials

Advanced composite materials (ACMs) are also known as advanced polymer matrix composites. These are generally characterized or determined by unusually high strength fibers with unusually high stiffness, or modulus of elasticity characteristics, compared to other materials, while bound together by weaker matrices. These are termed advanced composite materials (ACMs) in comparison to the composite materials commonly in use such as reinforced concrete, or even concrete itself. The high strength fibers are also low density while occupying a large fraction of the volume. Advanced composites exhibit desirable physical and chemical properties that include light weight coupled with high stiffness (elasticity), and strength along the direction of the reinforcing fiber, dimensional stability, temperature and chemical resistance, flex performance and relatively easy processing. Advanced composites are replacing metal components in many uses, particularly in the aerospace industry.

Transfer Moulding

Quality products with low cost manufacturing routes are the major objectives for the product development in any application. The current statement is evident for polymer-matrix composites, particularly in high end applications such as aerospace and mass transit structures. These applications require advanced composite materials tailored to meet the property demands posted by dynamic load conditions, and hence, the use of wide spectrum of constituents and architectures are vital to cater the needs. Consequently, the development of novel composite materials with the permutations of ingredients leads to the innovative processing techniques. To address the gap in the manufacturing with economical processing routes of thick sectioned advanced composite parts showing superior properties at different wall sections, an innovative composite manufacturing technology coupling resin transfer moulding (RTM) processing and vacuum applications, namely vacuum enhanced resin transfer moulding technology (VERTMTy), is conceptualized, proposed, and developed.

Advanced Composite Materials

Advanced composite materials are playing an increasingly important role in the design and fabrication of high performance space structures. Composite materials may be tailored for a particular application to establish a unique combination of high specific stiffness and strength, dimensional stability and specific damping which makes these materials ideal candidates for many applications in the hostile space environment. Demonstrative examples of typical applications to primary structures and payloads, each with a different set of performance requirements, are presented in this paper. Unfortunately, the use of polymer matrix composites for very long exposure to space has not been without problems due to various environmental effects which are discussed. The use of metal matrix composites is proposed as a possible solution to the problem. However, an understanding of the fundamental properties of composites and their response to space environmental effects is essential before the full benefit of these materials can be realized.

And Chemical Properties

Rapid expansion of technologies poses higher requirements to structural materials and items made of them. Conventional materials are being replaced by composite materials (composites). Different additives enhancing the properties of initial materials are used as reinforcement fibers of composites. Utilization of micro-and nanosize particles for production of present-day materials is paid much attention to. Whiskers are among such materials. These crystals have high strength, high chemical and temperature resistance. But for rational utilization of whickers of different chemical composition in composite materials one should know their physical and chemical properties. Objectives of the paper: to study physical and chemical properties of whiskers in different compounds, their composition and structure; to prove experimentally the feasibility of utilizing whiskers as a reinforcement fiber of composite materials. Object of study: specimens of whiskers of silicon nitride (Si3N4), aluminum oxide (Al2O3), aluminum nitride (AlN), and mullite (Al6Si2O13). Methods of investigation: thermal study of specimens, study of mechanical properties and chemical strength, and IR-spectroscopy. Results of study: specimens of whiskers have been studied and their mechanical properties have been tabulated for comparison. Extensive thermal investigation was followed by deduction of regularities and identification of chemical properties of whiskers. IR-spectra of whiskers have been studied and conclusions on molecular composition and on presence of impurities in some whiskers have been made.
