Abstract
A method of manufacturing a wheel guard may include injection-molding an adhesive layer, bonding an outer layer including a non-woven fabric and a sound-absorbing layer including thermoplastic resin with the adhesive layer in between, and forming the layers into a predetermined shape of the wheel guard, with the outer layer and the sound-absorbing layer bonded by the adhesive layer. The thickness of the outer layer may be 2 to 10 mm, the thickness of the adhesive layer may be 0.1 to 2 mm, and the thickness of the sound-absorbing layer may be 2 to 10 mm, before the bonding. A specific heat treatment layer may be formed on a non-adhesive side of the outer layer and may have an LM FIBER, a film, or a sheet.
