joining inconel support to a compostie materialplate

How to join a inconel yoke and a composite material plate .

I want to know what kind of resin that we can use to join them , and if we use some fastners, what kind of material can we use for the fastner that can with stand the highest temperature and stress too.

Inconel 718 fasteners are very good for stress and temp. Can't help with the bonding.

Could you give some more info about what kind of composite material, what temperatures and atmosphere will construction face?

Presumably the matrix resin in the composite part is good for the temperatures you're dealing with. Thus, the adhesive you select for the bond should be as good as the matrix material. If it's a high temperature cure epoxy then a film adhesive such as AF163 or FM300 would be typical.

Any fastener compatible with the materials will be good for the maximum temperature of the resin systems (even if it's polyimide). Usually fasteners used with Inco and carbon are stainless (e.g., 301 rivets or A-286 rivets or bolts), titanium (e.g., 45Cb rivets or 6-4 bolts) Monel rivets or Inco 718 bolts.

NB: watch out for the thermal stresses due to the cure cycle.
