COMPOSITE MATERIAL AND METHOD OF ITS PREPARATION

摘要

FIELD: composite materials for stomatology. ^ SUBSTANCE: proposed composite material has porous inorganic nonmetallic matrix and second material. Bending strength of matrix is no less than 40 Mpa as determined according to ISO 6 872; second material is just organic material which at least partially fills pores of matrix; elasticity modulus E of composite material is equal to or exceeds 25 Gpa determined according to ISO 10 477. Properties of proposed composite are between properties of ceramic and plastic materials, for example, friability is below that of ceramic materials but attrition resistance is higher as compared with that of polymers filled with inorganic materials. Specification describes method of production and application of material. ^ EFFECT: enhanced efficiency and reliability. ^ 13 cl, 4 ex
