Thestudyworked out an efficient optimization ofheat fusion conditionsbetween thermoplastics using molecular dynamics (MD)and a response surface method. The heat fusion process between polypropylene (PP)and polyethylene ( PE)and the uniaxial elongation for evaluation of theinterfacialbonding strength weremodeled byusing coarse-grained MD simulation.To determine the optimal conditions of heat fusion, experimental points were selected on the basis of a central composite design,and a second-order

The obtained optimal solution under constrained conditions yielded the highest strength compared with other experimental points and random points.
