Method for manufacturing a sandwiched sheet |
摘要 |
A method for manufacturing a sandwiched sheet includes grinding the natural plants into short segments and adding and mixing adhesive material into the short natural plants for forming a base material which is then heated and extruded for forming two or more boards. A woven layer of long fiber plants is engaged between the boards and includes a number of openings for allowing the base material of the boards to be filled into the openings of the woven layer and for forming a reinforced sandwiched sheet. Two layers of non-woven fabric material are engaged on the boards for forming smooth outer surfaces.
