Thermoplastic carbon composites

 

 

UVICOM Co Ltd. produces various thermoplastic compositions on a basis carbon fiber reinforcing material. Carbon fibers are characterized by a unique combination is elastic- strength indexes, electro and heat conductivity, biological inertness and low density. Realization of these properties in polymers and the adaptability to manufacture inherent in thermoplast, allow to use these materials instead of nonferrous metals, and in some cases instead of steel designs when especially sharply there is a problem of corrosion firmness. The basic properties Thermoplastic carbon composites (TCC) that found application in various industries resulted in the table

  • The heterogeneous polymeric system consisting of a thermoplastic matrix (polyolefins, polyamides, polysulphons, etc.), reinforced by a carbon fibre (the maintenance reinforcing material from 5 to 40 % of weights)
  • Issued in the form of black granules with a length 3-6 mm and diameter no more than 3 mm.
  • Mass fraction of a moisture no more than 0,2 % 
  • Half-finished product for manufacturing of details of technical appointment by a molding method under pressure, injection molding and tubing.

The material has following indicators of quality (for examples are used carbon polyamide plastics)

Main efforts of ours engineers and technologists are focused not on creation of a universal material, but on the offer of necessary assortment to the industry. Due to such a concept and taking into account raw polymeric base existing in Russia, compositions on the basis of polyamides and polyolefins have been developed.

COMPOSITE MATERIALS OF BIOMEDICAL APPOINTMENT WITH CARBON FIBER FILLING MATERIAL

(The patent of the Russian Federation № 2197509)


UVICOM Ltd. together with A. N. Nesmeyanov Institute of Organoelement Compounds the Russian Academy of Sciences with the assistance of scientific staff (The responsible developer from UVICOM Ltd.: Rashkovan I.A. Candidate of Science (Engineering), the responsible developer from A. N. Nesmeyanov Institute of Organoelement Compounds the Russian Academy of Sciences: Krasnov A.P. Doctor of Chemistry) develops composite polymeric materials of biomedical appointment with carbon filling materials. The basic components of offered materials along with plastic binder are biocompatible filling materials: hydroxyapatite, carbon fibers, etc.
The developed materials combine the high physical and mechanical indicators necessary for operation of constructional materials, such as durability at a bend, hardness, firmness, impact strength, with low value of a contact angle that provides good biocompatibility of a material with living tissues. The structure of materials redounds to formation of precursor cells from marrowy isolate.
As a result of tests it has been shown that the most successful is use of these materials as implant-prosthetic device for endoprosthesis replacement in surgery (the certificate of tests of a material on osteointegration and biocompatibility № 11 from …. Moscow State University of Medicine and Dentistry). Also their application effective in the form of products of a complex configuration in the bone plastic arts and maxillofacial surgery (the certificate of tests of products on osseointegration and biocompatibility № 15 from … Moscow State University of Medicine and Dentistry).
Availability of initial components, adaptability to manufacture of processing by a moulding method under pressure promotes successful use of these materials in craniofacial surgery, at prosthetics of various skeletal parts, and also for use in fixing radiotransparent and the biocompatible details used in the operational techniques. Of materials of this type using modern methods of processing make biocompatible     half-finished plates of a various thickness and products of a complex configuration for replacement of defects of a bony tissue.
UVICOM Ltd. has prepared the necessary technical specification coordinated with A. N. Nesmeyanov Institute of Organoelement Compounds the Russian Academy of Sciences, for manufacturing of biocompatible carbon materials.
