FIELD: chemistry.
SUBSTANCE: invention relates to composite material which can be used to protect surfaces of excavator buckets, hoppers, dump truck bodies and other mechanisms from abrasive wear under impact loads. The material is obtained by mixing mechanically activated ultra-high molecular polyethylene and aluminium oxide powder Al2O3. The aluminium oxide used is aluminium oxide Al2O3 of the corundum modification of two fractions with particle size of 0.1 mm and 0.3 mm in ratio 1:2 and in total amount of 18% of the weight of the ultra-high molecular polyethylene.
EFFECT: material for lining plates has high impact strength and wear resistance.
