Structural tape deployment apparatus

A tape drive comprises a roll of a tape that can be extended from a rolled state to an extended state. The tape includes a rigid material that supports the tape and a pliable material disposed at least partially on one side of the tape. A compression roller is disposed on a side of the tape and is biased toward the tape. A drive roller is disposed on the other side of the tape. The drive roller comprises an uneven surface that mechanically engages the pliable material of the tape, without protruding through the tape, as a result of the bias of the compression roller forcing the tape toward the drive roller. A motor turns the drive roller to extend the tape from the roll as the protrusions of the uneven surface of the drive roller mechanically engage the pliable material of the tape as the drive roller turns.
