The invention relates to a composite interior material for a motor car and a preparation method thereof. The composite interior material comprises 60-80% of high performance fibers, 10-20% of flame retardant fibers and 10-20% of hot-melt fibers; and the preparation method comprises the following specific steps of: 1) opening the high performance fibers, the flame retardant fibers and the hot-melt fibers by a bale opener; reopening the high performance fibers, the flame retardant fibers and the hot-melt fibers by using a rough opener; and then mixing the high performance fibers, the flame retardant fibers and the hot-melt fibers by using a cotton blending machine; finely opening the mixture by using a fine opener; and combing the mixture by using a carding machine; 2) by using a nonwoven needle-punched machining technology, lapping the combed fibers in a cross way by a lapping machine; and then carrying out needle punching on the fibers by using a needle machine; and processing the fibers by using a singeing machine and a glazing calendar; and 3) carrying out composite hot pressing on a fiber felt which is a needle-punched, singed and calendared semi-finished product; and finally, forming the composite interior material together with a thermoplastic resin.
