METHOD FOR MANUFACTURING ORIENTED-FIBER COMPOSITE MATERIAL, ORIENTED-FIBER COMPOSITE MATERIAL MANUFACTURED THEREBY, REFLECTIVE POLARIZING LIGHT FILM COMPRISING ORIENTED-FIBER COMPOSITE MATERIAL AND METHOD FOR MANUFACTURING REFLECTIVE POLARIZING LIGHT FILM
The present invention relates to a method for manufacturing in-situ oriented-fiber composite material, the method simultaneously extruding, using thermoplastic members, matrix ingredients and fiber ingredients, and passing same through a nozzle of a set cross-sectional shape, weight and fill ratio of the fiber ingredient, thereby aligning the fiber ingredients within the matrix in one direction one single continuous step, and thus, by means of the production method, the process is shortened, the thinning of the thickness of the oriented-fiber composite material is attained, and particularly, filling, distribution and reinforcement of the fiber within the matrix can be effectively controlled and a high density of the fiber can be attained. Furthermore, the present invention provides an element exhibiting superbly effective reflective polarization by controlling so that the lengthwise refractive index of the matrix is lower than the lengthwise refractive index of the fiber ingredients in the oriented-fiber composite material, thus the element can replace conventional reflective polarizing light film and can be effectively used as an optical element in other fields.
