Investigation of the effect of drilling induced delamination and tool wear on residual strength in polymer nanocomposites
Drilling-induced delamination, fractures, debonding, tool wear, and matrix fuzzing all reduce the residual strength of polymer composites. The novelty of the present studies lies in incorporating nano-fillers Graphene and Montmorillonite Clay at a 2% weight percentage for the toughening matrix to mi...

| description | Drilling-induced delamination, fractures, debonding, tool wear, and matrix fuzzing all reduce the residual strength of polymer composites. The novelty of the present studies lies in incorporating nano-fillers Graphene and Montmorillonite Clay at a 2% weight percentage for the toughening matrix to minimize drilling-induced residual stresses and tool wear. Combining the matrix's thermal and mechanical properties with fibers reduces fibrous composite macro and micro residual stresses. Interlaminar shear strength rose by 16%-23% and fracture toughness by 22% using nanofillers, minimizing drilling-induced crack delamination and composite tensile strength deterioration. Nanofillers increased hole laminate tensile strength retention and time to failure. Tool wear and delamination factors rose at the hole exit with increased drilled holes but improved at the entry by 16%. This study shows the intricate link between composite material composition, process variables, and structural integrity in drilling-exposed composites. |
