NOVELTY - Polymeric sandwich structure (10) having enhanced thermal conductivity, comprises a first layer (12) formed from a first polymer matrix (14) and including a first fiber reinforcing sheet (16) embedded within the first polymer matrix; a second layer (18) formed from a second polymer matrix (20) and including a second fiber reinforcing sheet embedded within the second polymer matrix; and a third layer (24) set between the first and second layers. The third layer is formed from a third polymer matrix (26) having graphene nanoplatelets (28) interspersed, where each of the first and second fiber reinforcing sheets is made of reinforcing fibers and includes a respective set of staggered discontinuous perforations, where each respective set of staggered discontinuous perforations defines a respective first set of reinforcing fibers having a respective first length and a respective second set of reinforcing fibers having a respective second length longer than the respective first length. USE - Polymeric sandwich structure having enhanced thermal conductivity. ADVANTAGE - The polymeric sandwich structure has enhanced thermal conductivity, improved overall flowability and moldability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing a flowable polymeric sandwich structure having enhanced thermal conductivity, which involves: i. dispersing graphene nanoplatelets in a solvent to produce a graphene nanoplatelet/solvent mixture; ii. ultrasonically mixing the graphene nanoplatelet/solvent mixture to achieve a predetermined level of homogeneity; iii. combining the graphene nanoplatelet/solvent mixture with a polymer matrix to produce a graphene nanoplatelet/solvent/polymer matrix mixture; iv. evaporating at least a majority of the solvent from the graphene nanoplatelet/solvent/polymer matrix mixture to produce a graphene nanoplatelet/polymer matrix mixture; v. pressurizing the graphene nanoplatelet/polymer matrix mixture according to a pressure profile; vi. dispersing the graphene nanoplatelet/polymer matrix mixture onto a first carrier film; vii. sending the graphene nanoplatelet/polymer matrix mixture and first carrier film through a doctor blade arrangement to achieve a predetermined thickness of graphene nanoplatelet/polymer matrix mixture on the first carrier film; viii. heating the graphene nanoplatelet/polymer matrix mixture to achieve a predetermined degree of cure and/or a predetermined viscosity of the graphene nanoplatelet/polymer matrix mixture for producing a core layer; viii. providing a first layer formed from a first polymer matrix with a first fiber reinforcing sheet embedded within the first polymer matrix, and a second layer formed from a second polymer matrix with a second fiber reinforcing sheet embedded within the second polymer matrix; ix. producing a respective set of staggered discontinuous perforations in each of the first and second fiber reinforcing sheets using a perforation cutting head or a laser for producing respective first and second perforated layers; and x. stacking the core layer between the first and second perforated layers.
