Pulling (tensile), which is also the direction steel is unusually strong in (from a materials perspective).

Compression wise it’s close to a wet noodle the way it’s manufacturable (though that has more to do with cost/practical production/gathering methods - if we could get a solid chunk of it I imagine it would be pretty strong in compression).

Sliding, it’s a fiber, so very weak in that sense (barring the same scenario above). It actively flexes, so isn’t strong’
