Abstract: The characteristics of jute and polypropylene fibers were analyzed respectively,and the reasonable blending ratio of the two fibers was determined for development of automobile interior ceiling lining boards.The processing route and chief technical parameters such as degumming,flame retardant treatment, opening and mixing,carding and web forming,take-in operation,curing and hot pressing were investigated during the development of the material.The properties of the jute and polypropylene composite lining board were compared with those of the glass fiber reinforced plastic composite and the results indicated that the performance indexes of the automobile interior lining board of jute and polypropylene non-woven composite material can meet the related requirements of the automobile industry with such properties as bursting strength,extensibility and permeability exceeding those of the glass fiber reinforced plastic composite.
