The factors including pressure and temperature which play important role in fusion bonding were analyzed in molecular level.
Introduction With many advantages in terms of low cost, mechanical properties, and ease of processing polymer has a wide range of applications in MEMS and is replacing conventional materials such as glass and silicon etc [1].
A number of studies have demonstrated the application of molecular simulation methods to compute mechanical properties of polymers [8,9] and results obtained from these simulations have been encouraging since they agree rather well with the laboratory measurements.
The deformation was affected by pressure seriously.
Without considering other factors relatively small pressure and high temperature relatively are necessary for precise fusion bonding.

Studies have shown that adding CNTs to photocurable polymers used in SLA can significantly alter their mechanical behavior, impacting both impact resistance and fatigue life—key factors in the longevity and performance of prosthetic limbs [1].
The extensive application of CNTs across diverse fields is largely due to their ability to undergo significant mechanical deformations, which affect their electronic, magnetic, optical, and chemical properties [5].

Efforts have also been paid to improve TWB formability which focuses on the factors such as welding technologies, the thickness of parent metals as well as stress differences [9, 10].
Our previous work has shown that the integrated strength, which is affected by material properties and thicknesses, can be used as a combined index to evaluate the formability of TWB [12].
Material properties used in the model are listed in Table 1.
The TWB used here is made up of base metals with different material properties.
From the simulation and experiment results, it was found that: 1) The uneven deformation between two sides' base metals in the forming process is possibly a main factor to degrade the formability of TWB; while one major cause of the uneven deformation can be the discrepancy of integrated strength which is consisted of materials properties and thickness. 2) The discrepancy of integrated strengths on base metals can affect both cracking trend and cracking type.
