“…[18] A detailed investigation on the enhancement of the mechanical and thermal properties of the biofibers, biofilms, biopolymer, and biocomposites from the renewable and bio-based materials was documented. [19][20][21] Among the bio-based materials, different types of biopolymers, like Chitosan, polysaccharide, polylactic acid, PVA, epoxidized plant oil is mentionable. A few drawbacks, for example, prone to fungi and bacteria, low shelf life, gas permeability, poor mechanical properties and moisture sensitivity were also noticed.…”

Fishbones are hydroxyapatite-based waste materials. They can be used in the form of particles as filler or additive in polymer composites. The surface of the particles can be modified using heat or thermal treatment. In this work, the fishbone particles (FBPs) were used in epoxy composites for the semi-structural applications. The composites were prepared using a solution-cast method. The effect of thermal treatment of the FBPs on the performance of the composites was investigated. The mechanical testing, thermo-gravimetric analysis, and differential scanning calorimetry measured the performance of the composites. The chemical structure and morphological properties of the composites were observed through Fourier transform infrared spectroscopy and scanning electron microscopy, respectively. Results showed that the tensile and flexural strength of the composites were improved by 30% and 200%, respectively, compared to the neat epoxy (NE) as an effect of the thermal treatment. It was also noticed that theT g , T m and T c of the modified composite were found significantly higher compared to other composites. The FBPs formed a hybrid domain within the composites when they interact with the epoxy. Such strong bonding can protect the composites from the external forces. Based on the performance, it can be suggested that the composites can be used where a semi-flexible scaffold is required.

“…Thanks to their recyclability and renewability, biocomposites allow to comply with more and more stringent environmental protection regulations [ 4 , 5 ] improving also the cost effectiveness [ 6 ]. Increasing the mechanical performance of these materials is a mandatory task to spread their use not only in non-structural applications, but also in semi- and proper structural applications actually limited by their failure mechanisms [ 7 ]. The experimental evidence has shown that biocomposites reinforced by natural fibers present damage mechanisms [ 8 , 9 , 10 , 11 , 12 , 13 ] somewhat quite similar to those observed in traditional composites reinforced by synthetic fibers [ 14 ], as debonding, delamination, inter-fiber fractures and fiber fractures.…”

New Concept in Bioderived Composites: Biochar as Toughening Agent for Improving Performances and Durability of Agave-Based Epoxy Biocomposites

et al. 2021

Biocomposites are increasingly used in the industry for the replacement of synthetic materials, thanks to their good mechanical properties, being lightweight, and having low cost. Unfortunately, in several potential fields of structural application their static strength and fatigue life are not high enough. For this reason, several chemical treatments on the fibers have been proposed in literature, although still without fully satisfactory results. To overcome this drawback, in this study we present a procedure based on the addition of a carbonaceous filler to a green epoxy matrix reinforced by Agave sisalana fibers. Among all carbon-based materials, biochar was selected for its environmental friendliness, along with its ability to improve the mechanical properties of polymers. Different percentages of biochar, 1, 2, and 4 wt %, were finely dispersed into the resin using a mixer and a sonicator, then a compression molding process coupled with an optimized thermomechanical cure process was used to produce a short fiber biocomposite with Vf = 35%. Systematic experimental tests have shown that the presence of biochar, in the amount 2 wt %, has significant effects on the matrix and fiber interphase, and leads to an increase of up to three orders of magnitude in the fatigue life, together with an appreciable improvement in static tensile strength.

A novel cellulosic fibre was extracted from the peduncle portion of the fish tail palm tree and the extracted fish tail palm fibre was treated with different concentrations (1%, 5%, and 9%) of silane solution. The characteristic analysis on chemical, functional, mechanical and surface property of the extracted fish tail palm fibres were investigated through chemical composition analysis, Fourier Transform InfraRed spectroscopy (FT-IR), single fibre tensile test, and Scanning Electron Microscopy (SEM). Chemical analysis results indicate that silane treatment improved the cellulose content of the fish tail palm fibre. The highest cellulose content of 72.51% was observed in the 9% silane treated fish tail palm fibre. Also, it improved crystallinity index value of 62.5% for 5% silane treated fibre, which is confirmed through the X-ray diffraction analysis. FT-IR result indicates the removal of hemicellulose at characteristic wavelength of 1745 cm −1 for 5% silane treated fish tail palm fibre. Tensile property of the silane treated fish tail palm fibre (1, 5, and 9%) shows an increased tensile strength of 7.3%, 12%, and 6.6% as compared to raw fish tail palm fibre. Moreover, this type of novel natural fibres can reduce the cost while offering competent performance during the polymer-based product development.
