The method is prepared by mixing silicate material and lime material with water and hydrothermally reacting with stirring under a high temperature and high pressure saturated water vapor pressure of 120 ~ 160 ℃ in a high pressure cooker equipped with agitator to produce calcium silicate quasi-crystal of CSH (Ⅰ). After preparing the main slurry, water glass was added to the slurry to prepare a secondary slurry containing amorphous calcium silicate or amorphous calcium silicate, and after adding and mixing the reinforcing fiber and the organic resin in the form of emulsion, agglomerates were added to aggregate the slurry solids. To prepare a tertiary slurry of a hybrid aggregate composed of calcium silicate and an emulsion resin under a reinforcing fiber, and the slurry was pressurized and dehydrated to obtain wet slurry. The molded article in the womb loading type autoclave characterized in that the random number sequence prepared by reacting at a high temperature and a saturated steam pressure of the high pressure of 170~250 ℃.
