  "textContent": "A lightweight, multi-layered composite substrate for a vehicle interior material and a method for manufacturing the same are disclosed. A method for manufacturing a lightweight, multi-layered composite substrate including a core layer being a foam sheet and reinforcement layers stacked on both surfaces of the core layer includes preparing the foam sheet, forming each of the reinforcement layers by forming a low-density reinforcement sheet by mixing a natural fiber with a synthetic fiber by carding, subjecting the mixed natural fiber and synthetic fiber to cross wrapping and needle punching, coating polyolefin-based powder to a weight per unit area of 10g/m 2 to 100g/m 2 on the low-density reinforcement sheet, and pressing the low-density reinforcement sheet by a heat roller set to 150 to 230°C, and obtaining a multi-layered composite substrate by stacking the reinforcement layers on both surfaces of the foam sheet by heat.",
