Systems and methods for manufacturing laser-perforated nanoreinforced materials are disclosed. A honeycomb core (300) may utilize a perforated top sheet (100;320) and a microperforated overlay film (200;340) coupled to the perforated top sheet (100;320). The perforated top sheet (100;320) and/or the microperforated film (200;340) may include thermally conductive nanomaterials (130). The perforations (140;325) in the top sheet (100;320) and the microperforations (220;345) in the film (200;340) may be laser drilled. The nanomaterials (130) may dissipate heat generated by the laser drilling, allowing for increased perforation speeds.
