I sectioned a cheap carbon seatpost at work a while back and the end of that was full of a white resin filler. We couldn’t really work out why it was there but our best guess was it was some kind of consolidator to make the moulding cheaper/easier/faster or they simply hadn’t been able to work out what sort of insert to use in the mould.
