the present disclosure is directed to a roof lining for a vehicle and a manufacturing method thereof , and in particular , to the roof lining for a vehicle using a composite material having basalt fibers mixed into a thermoplastic resin as a substrate . the resulting roof lining can be lightweight , have enhanced sound absorbency and increased heat insulating properties . due to the use of basalt fibers , which do not coat incinerator walls like glass fibers do , the roof lining is more easily recycled .
