PURPOSE: A sol particle-confining bee-hive type reinforcing material using polylactic acid as main ingredient is provided to control biodegradation property and obtain excellent rigidity, tensile strength, and thermal stability. CONSTITUTION: A sol particle-confining bee-hive type reinforcing material using polylactic acid as main ingredient(400) can have either a cell shaped net structure or a cell network structure. A manufacturing process of the cell shaped net structure comprises the following steps: processing filament yarn or processing a core to a sheet; welding one part of the laminated sheet with ultrasonic waves; and using a core yarn in which filament is diffused in a bundle shape and welded as woof reinforcing yarn(410) and/or warp reinforcing yarn(420). A manufacturing method of a cell network structure comprises the following steps: forming a meshed sheet(440) having air gaps(430) by crossing the woof reinforcing yarn and warp reinforcing yarn; fusing and interlinking the sheet in width direction; pulling the sheets in a specific direction.
