Abstract
The present invention relates to a multi-layered composite material manufactured by thermocompressing a multi-layered sheet, comprising: a first sheet layer formed from a solution containing nanofibrillated cellulose and a first thermoplastic matrix polymer; and a second sheet layer formed from a solution containing a second thermoplastic matrix polymer. The multi-layered composite material of the present invention has the high strength and high elastic modulus.
