Composite reinforced degradable material as well as preparation method and application thereof

The invention discloses a composite reinforced degradable material as well as a preparation method and application thereof. The composite reinforced degradable material disclosed by the invention is prepared from the following components in parts by weight: 31.2 to 65.2 parts of racemic polylactic acid, 20 to 40 parts of nano-hydroxyapatite, 0.5 to 3 parts of MPEG-PLA, 0.2 to 0.8 part of epoxidized octadecenoic acid and 15 to 25 parts of L-polylactic acid fiber. The epoxidized octadecenoic acid contains an epoxy group and a carboxyl group, and the epoxy value is greater than or equal to 4.0. According to the composite reinforced degradable material, epoxidized octadecenoic acid is combined with the nano-hydroxyapatite and the MPEG-PLA copolymer, and after the epoxidized octadecenoic acid is matched with the L-polylactic acid fiber, the strength of the composite reinforced degradable material can be effectively improved, and the nano-hydroxyapatite can be promoted to be uniformly dispersed; the neutralizing ef
