FIELD: chemistry.
SUBSTANCE: invention relates to composite materials based on calcium phosphate ceramic with improved strength properties and can be used in filling bone defects in traumatology and orthopaedics, maxillofacial surgery and dental surgery. To obtain reinforced porous composite materials based on hydroxyapatite and tricalcium phosphate, a porous ceramic matrix of a calcium phosphate ceramic with the ratio Ca/P ranging from 1.5 to 1.67 is saturated with 1-5% solution of average molecular or high molecular chitosan in 8% acetic acid at residual pressure of 0.1 to 0.3 Pa and holding for 10 to 30 minutes, followed by drying at room temperature for 24 hours.
EFFECT: invention increases strength of the composite material 8-9-fold.
