As mentioned above, even friction stir is set at 5% little than the thickness of slab of aluminium alloy element 3 with the compression distance of throw G, still can engage resin component element 2 and aluminium alloy element 3, but in order to obtain enough hot strengths, comparatively it is desirable to, friction stir is set at more than 5% of thickness of slab of aluminium alloy element 3 with the compression distance of throw G.

On the other hand, if set greatlyyer with the compression distance of throw G friction stir, then, the formed plastification of friction stir zone causes metal and mixed with resin because of may contacting with resin component element 2.In addition, if set greatlyyer with the compression distance of throw G friction stir, then can be to the excessive load of friction stir device effect.Therefore,, then comparatively it is desirable to, friction stir is set at below 20% of thickness of slab of aluminium alloy element 3 with the compression distance of throw G if consider these factors.
