The utilization of nanoparticle filled composite materials in many different engineering fields has undergone a tremendous increase.
In some situations, these materials may experience serious damage during the drilling of the nanoparticle-reinforced polymer (NRP) composite materials, such as fiber pullout, matrix delamination, and cracking.
The use of nanoparticulate composite materials has experienced an enormous increase in many different engineering fields as mentioned earlier.
