Disclosed herein are relates to a method for compressing a laminate and a method for manufacturing a ceramic electronic component including a laminate. The method for compressing a laminate includes: preparing a laminate; pressurizing the laminate from a first pressure to a second pressure; heating the laminate from a first temperature to a second temperature; maintaining compression of the laminate at the second pressure and the second temperature for a predetermined time; cooling the laminate from the second temperature to a third temperature; and depressurizing the laminate from the second pressure to a third pressure, wherein the second temperature is 70 C. to 150 C.

The present invention provides a preparation method of natural bamboo fiber composites and an application thereof. The method involves treating bamboo with a specific composition of treatment solution to obtain natural bamboo fibers with a length and a diameter that meets certain conditions; then, the natural bamboo fibers are combined with polypropylene fibers to prepare composites, and by controlling process conditions of a preparation process, a high-strength and excellent comprehensive performance composites is finally prepared. The composites produced by the method can be used as a bottom baffle of the air conditioning box in automobiles. Through the method, a high-performance natural bamboo fiber composites are provided.
