Abstract
Official abstract text for this publication.
Systems and methods for manufacturing laser-perforated nanoreinforced materials are disclosed. A honeycomb core may utilize a perforated top sheet and a microperforated overlay film coupled to the perforated top sheet. The perforated top sheet and/or the microperforated film may include thermally conductive nanomaterials. The perforations in the top sheet and the microperforations in the film may be laser drilled. The nanomaterials may dissipate heat generated by the laser drilling, allowing for increased perforation speeds.
First claim
Opening claim text (preview).
We claim: 1. A method of drilling holes in an acoustic panel composite substrate comprising: fabricating an acoustic panel composite substrate comprising a fiber reinforced composite ply and a surface film comprising nanoparticles disposed on the fiber reinforced composite ply; and drilling holes in the acoustic panel composite substrate, wherein the nanoparticles in the surface film are configured to conduct heat away from the fiber reinforced composite ply generated by the drilling of the holes. 2. The method of claim 1 , wherein the holes are drilled with at least one of a drill bit and a laser beam. 3. The method of claim 1 , wherein the nanoparticles comprise at least one of carbon nanotubes, carbon nanofibers, and graphene nanoplatelets. 4. The method of claim 1 , wherein the holes are drilled at a rate of at least 2 holes per second for every laser beam or drill bit. 5. The method of claim 1 , wherein the nanoparticles are configured to dissipate heat generated by the drilling the holes. 6. The method of claim 1 , wherein the drilling the holes comprises drilling the holes with a plurality of laser beams or drill bits. 7. The method of claim 1 , wherein the composite ply comprises nanoparticles.
