A beneficiated fiber (12) and composite including a fiber having a lumen with voids (20). A suspension including a bonding agent, chemical blowing agent, and catalyst is drawn into the lumen by a capillary action to beneficiated the fiber. The beneficiated fiber may be imbedded with a polymeric material to form the composite. The natural voids of the lumen are preserved by the suspension causing the fiber to maintain natural density and strength characteristics.

La présente invention concerne une fibre enrichie et un composite comprenant une fibre présentant une lumière avec des vides. Une suspension comprenant un liant, un agent d'expansion chimique et un catalyseur est entraînée dans la lumière par une action capillaire afin d'enrichir la fibre. Un matériau polymère peut être incorporé à la fibre enrichie afin de former le composite. Les vides naturels de la lumière sont préservés par la suspension, ce qui amène la fibre à maintenir des caractéristiques de densité et de résistance naturelles.
