Project summary

One of the most significant problems of modern civilization is the problem of solid household and industrial waste utilization, in particular, utilization of polyethileneterephthalate unfit to natural decomposition [1].

On the other hand, development of various fields of engineering including mechanical engineering, electrical and building industry, production of consumer goods etc. is in need of a wide scale of composite materials (composites). Composites are characterized by the type of their matrix. The most widespread modern composites have metallic matrix (MMC) or ceramic one (CMC). These composites belong to relatively expensive materials.

The subject of this project is development of the novel composite material on the base of utilization of certain fractions of solid industrial and household waste containing polyethyleneterephthalate (PET), wood sawdust and other woodworking waste, textile manufacture waste, food industry waste such as sunflower husk etc. The composite offered (PETMC) consist of PET with function of binding matrix and one or several filling materials from the list of mentioned above solid organic waste materials [2]. The latter ones determine significantly basic mechanical, electrical, physical-chemical and other functional properties of PETMC.

The most significant feature of this project is utilization of not the primary PET but the secondary one. It is used in the form of fine-milled used articles made of PET (bottles, glasses and so on) or PET-articles production waste. Extermination of such waste is now one of the most significant problems of environment protection since natural decomposition of PET is impossible and utilization of this material for any purpose does not have any principal solution. PETMC solves this problem.

The novel materials of PETMC group are produced by mixing and heating of mentioned above components followed by compaction of the mixture under elevated temperature and high enough pressure. The PETMCs obtained by this method have high strength and hardness (at the level of soft steel or copper), high wear resistance, very low water absorption, low thermal and electric conductivity. With respect to this combination of properties, such materials seem to be very prospective for consumers in mechanical engineering, electrotechnical and some other fields of industry.

The essential feature of PETMC materials is its extreme cheapness because the components making it are household and industrial waste. That is why, this project presented opens new outlooks in solving the problem of both utilization of solid waste and development of resource-saving technologies.

PETMC’s functional properties are forming in dependence on its breakup, temperature and pressure of their pressurizing. These dependencies are the subject of detailed studies being the main content of this project.

The scientists and the specialists representing organizations taking part in this project have been have many years experience on the problems of creation of novel composite materials of various composition and purpose. Their works are well known in Russia and abroad. It proves high scientific level of the research group and assures success in fulfilling the project.
