• OS1704 Effect of bubbles on strength of dissimilar materials laser spot joint between metal and plastic

抄録

Dissimilar materials spot joining between polyethylene terephthalate (PET) and type 304 stainless steel (SUS304) was carried out by using fiber laser. Bubbles were formed in PET side near the interface by heating due to laser irradiation. Contact force was applied at bottom of joining part to control the formation behavior of bubbles. Bubble area ratio and density of bubbles increased with increase the contact force. Tensile shear strength of the joint decreased with increase the bubble area ratio. Bubbles formed at the interface were assumed as multiple cracks to evaluate stress intensity factor. It is speculated that higher density of bubbles formed by applying higher contact force induces connecting of cracks easily. Strength of the joint could be controlled by applied contact force as a result of change in formation behavior of the bubbles.
