  Natural fibers composites are considered as sustainable alternative to
synthetic composites due to their environmental and economic benefits. However,
they suffer from poor mechanical and interfacial properties due to a random
fiber orientation and weak fiber-matrix interface. Here we report
nano-engineered graphene-based natural jute fiber preforms with a new fiber
architecture (NFA) which significantly improves their properties and
performances. Our graphene-based NFA of jute fiber perform enhances Young
modulus of jute-epoxy composites by ~324% and tensile strength by ~110% more
than untreated jute fiber composites, by arranging fibers in parallel direction
through individualisation and nano surface engineering with graphene
derivatives. This could potentially lead to manufacturing of high performance
natural alternatives to synthetic composites in various stiffness driven high
performance applications.
