Abstract:In this work, an investigation has been carried out on the sound absorption properties of the microperforated composites prepared by filling natural luffa fiber and synthetic luffa fiber. These composite structures are created by 3‐dimensional printing of polylactic acid, which exhibits excellent biodegradability. After preparing the structure, the micro‐perforation is done at the top of the composite with the help of a heated cylindrical drill. During the printing process, the infill density (printing paramet… Show more
