Background:
This era has seen outstanding achievements in materials science through
the advances in natural fiber-based composites. The new environmentally friendly and sustainability
concerns have imposed the chemists, biologists, researchers, engineers, and scientists to discover
the engineering and structural applications of natural fiber reinforced composites.
Objective:
To present a comprehensive evaluation of information from 2000 to 2018 in United
States patents in the field of natural fibers and their composite materials.
Methods:
The patent data have been taken from the external links of US patents such as IFI
CLAIMS Patent Services, USPTO, USPTO Assignment, Espacenet, Global Dossier, and Discuss.
Results:
The present world scenario demands the usage of natural fibers from agricultural and
forest byproducts as a reinforcement material for fiber reinforced composites. Natural fibers can be
easily extracted from plants and animals. Recently natural fiber in nanoscale is preferred over micro
and macro scale fibers due to its superior thermo-mechanical properties. However, the choice
of macro, micro, and nanofibers depends on their applications.
Conclusion:
This document presents a comprehensive evaluation of information from 2000 to
2018 in United States patents in the field of natural fibers and their composite materials.
