The invention discloses a flexible connector assembly for a flexible spraying pipe of a solid rocket engine and a manufacture method thereof. The flexible connector assembly comprises a front flange body and a back flange body which are connected through an elastic piece group and a reinforcing piece group. The elastic piece group is formed by n+1 layers of homocentric sphere annular elastic slices which are matched. The reinforcing piece group is formed by n layers of homocentric sphere annular rigid slices, and n is a natural number. The n+1 layers of homocentric sphere annular elastic slices and the n layers of homocentric sphere annular rigid slices are of an interactive interval bonding structure and are subjected to heat vulcanization bonding with the back flange body to form a heat bonding composite body. The heat bonding composite body and the front flange body are bonded through a cold adhesive to form a sphere homocentric connection body. The flexible connector assembly is high in bonding force, goo
