Why composite changes the choice
The blind side sets the footprint. The material pair and the head side set the rest.
The blind-side footprint is the point
Composite fasteners have larger tail footprints, which improve pull-through and bearing strength in laminate (MIL-HDBK-17-3F §6.3.1). For blind attachments to composite, the handbook calls for a large blind-side footprint in titanium or A286 (C-32).
Galvanic is material-driven
MIL-STD-889C rates aluminum and carbon/alloy steel incompatible with graphite, on whichever side of the joint the carbon sits. That points to titanium or A286 regardless of which side is blind.
Head-side composite still matters
Pull-through and head bearing matter on the head side too: MIL-HDBK-17-3F prefers 100° tension heads in composite and cautions on 130° heads (§6.3.3.3). The blind side drives the bulb; the material pair + environment drive everything else.
