1. A fibrous composition, comprising:
a first fiber population that comprises a plurality of first fibers having a first bonding group disposed at least on a surface of the first fibers,
the first fibers comprising a first matrix material; and
a second fiber population that comprises a plurality of second fibers having a second bonding group disposed at least on a surface of the second fibers, and
the second fibers comprising a second matrix material,
the first bonding group being configured to interact with the second bonding group so as to introduce crosslinks between at least one fiber of the first fiber population and at least one fiber of the second fiber population upon application of a mechanical manipulation that reduces a distance between the first and the second bonding groups, and
wherein the crosslinks persist following application of the mechanical manipulation, wherein the fibrous composition retains a shape achieved following application of the mechanical manipulation.
