Is there a glue / epoxy that's viscous enough to be absorbed by chipboard and can also bond metal?
I have a project where I want to figure out how to secure a metal part to chipboard without using nails etc. I've tried a two part epoxy called ergo 1309 that is good for bonding metals and wood, but because it doesn't flow and is more like a gel, it doesn't absorb into the wood, and so the metal can be torn off the board because the wood chips are easily torn off from each other.

Glue doesn't work by "being absorbed into the wood" as you say. It forms a bond to the wood surface.
The problem here is your choice of material, chipboard. This s simply a compressed mass of wood chips held together with some glue. As you have discovered, those particles are not held together all that strongly.
It's not clear why you can't use some other means of fastening to this board but perhaps you might consider changing to something that has more going for it than chipboard.
If you must use the chipboard, you should consider using some thru-bolts with washers to spread out the load on the chipboard side. Alternatively some screws which are designed to hold well in such materials.
