“…It was taken from literature to be 400 MPa–980 MPa. 16,20 Using a matrix yield stress of 7 MPa that was found from the plastic tensile tests, the critical fiber length was estimated to be 1.45 cm (σ f = 400 MPa) to 3.54 cm (σ f = 980 MPa). A sample calculation is shown below …”

“…Banana fibers are a lignocellulic bast fiber that comes from the pseudo-stem of the banana plant. 16 The fibers were harvested and processed in Sri Lanka by the Yaal foundation – a group associated with banana farmers. They are made using waste from this industry using a semi-manual multifiber bundle decorticating machine that was donated by a German NGO.…”

“…The fiber tensile strength was taken from literature to be 400 MPa-980 MPa. 16,20 The interfacial shear bond strength s was approximated to be the shear yield strength of the plastic matrix. It assumes that the bond between fiber and matrix is perfect which is not the case here.…”

In the framework of the waste for life Sri Lanka project, low value industrial low-density polyethylene waste plastics and banana fibers made from agricultural waste are upcycled into affordable eco-friendly building products. This creates income for the local communities while mitigating waste disposal and reducing ecological problems. Within this context, a robust manufacturing method using compression molding was developed. Panels with varying fiber content were manufactured using unchopped and chopped fibers. Low-density polyethylene characterization using Fourier transform infrared spectroscopy and differential scanning calorimetry to compare plastic sources was conducted. To reduce cost, no fiber treatments or compatibilizers were used. An estimate of critical fiber length was found to be around 1.45 cm to 2.5 cm. A trend of increasing strength with fiber content (up to 40 wt.%) was achieved by using longer fibers than in the previous research. Handling and dispersion of the fibers were increased by chopping the fibers to 20 cm lengths, which led to an increase in tensile strength due to easier manufacturing. Cross-ply panels made with fibers chopped to a length of 20 cm were found to be strongest peaking at around 40 wt.% with a tensile strength of 32.8 MPa, a fourfold increase compared to a raw low-density polyethylene (0 wt.%) panel.

“…From the analysis, it concluded that thermal performances of natural fibers improve by surface treatment. Increase of treated fibers decomposition temperature is due to the removal of smaller molecules (and thus an increase in molecular weight) and amorphous from surface fiber . Furthermore, it is highly recommended that the mode of decomposition and thermal degradation during fabrication of natural fibers reinforced polymer matrix composites under influence of heat for optimization process parameters …”

In this research, biodegradable composites were prepared with zein as a polymer matrix and oil palm empty fruit bunch (OPEFB) as fiber reinforcement. The fibers were treated with sodium hydroxide (NaOH). The effects of sodium hydroxide treatment on sound absorption, thermal stability, and fiber-polymer matrix interaction in composites were examined. The acoustical sound absorption coefficients of the composites were evaluated using two-microphone transfer function impedance tube method. The spectral, thermal, and morphological studies of the composites were analyzed and characterized using scanning electron microscope (SEM), thermogravimetric analysis (TGA), and Fourier transform infrared (FTIR) spectroscopy. It was found that in all the biodegradable composites, the sound absorption coefficients increased as the frequency increased. Increases in fiber loading caused sound absorption coefficients of the composites to increase. The sodium hydroxide treatment showed a better interface adhesion on fiber and zein matrix. It was also found that this treatment increased the sound absorption coefficients. This was supported by qualitative analysis on the SEM micrographs and FTIR spectrum.

In the present investigation, the cellulose fibers were extracted from Arundo donax through a three‐step treatment. The effects of the alkaline pre‐treatment, acid hydrolysis, and soxhlet‐based extraction on the qualitative and quantitative attributes of the resultant cellulose fibers were investigated. The results of the present study signify a positive correlation between chemical treatment and cellulose content. The overall yield conversion of cellulose was recorded as 156.67%, after Soxhlet‐based purification. It was also observed that the moisture content, percentage of water absorption, rate of water absorption, and ash mass fraction gradually declined after each treatment step. The correlation between the chemical treatment with quantitative and qualitative attributes revealed a gradual increment in cellulose content, crystallinity index, and purity of cellulose fiber extracted from A. donax. The FTIR spectra emphasized that the obtained cellulose was free from impurities after Soxhlet‐based extraction. Simultaneously the DTG curve of A. donax fiber revealed a low rate of derivatization in the fibers extracted after Soxhlet treatment. The SEM and EDX analysis illustrate that the cellulose fibers were devoid of impurities as well as contamination of heavy metal ions.
