| Summary: | As a result of the depletion of petroleum resources coupled with increasing awareness in
environmental friendly issues, engineering are being integrated to provide the impetus for
new materials and products that are compatible with the environment and independent of
fossil fuels. Bio-composites derived from plant-derived fiber and crop/bio-derived plastics
(biopolymer/biopiastics) are more Eco-friendly and fit well into this new paradigm shift.
These materials also can form the basis for sustainable and Eco-efficient products that
often results in biodegradable and lightweight structures having high stiffness and tailored
properties for specific applications. Thereby, main objective of this work is to develop
biocomposites board by using the thermosetting protein-based materials which derived
from renewable feedstock such as egg white proteins (albumen). The investigation is
about the effect of fibre content on the physical and mechanical properties of the
cottonlalbumen composites (CAC). The composites structures, functional chemical groups
and thermal stability were characterized by XRD, FTlR and TGA analysis, respectively.
The fiber content in the CAC was varied from 0 to 16% w/w. As expected, the
incorporation of cotton fiber produces a substantial increase in term of density, strength
and toughness of the CAC. The maximum tensile strength of 8 MPa and impact strength
of 18.0 kj/m², respectively, was found in the CAC with 10% w/w of fiber content. The
morphology structures examined by using SEM justify the experimental results obtained
from the mechanical analysis. The mechanical strength of the composite was optimized
with the addition of 10% w/w cotton fiber because of sufficient wettability of the matrix
albumen with the cotton fiber. This is also attributed due to close packing and
entanglement of the fibers. |
