“…As pointed out in the pure MSSF as shown in Figure 1(a), the presence of lignin and hemicelluloses can be traced at C=O and C-O bonds in the fresh MSSF at peaks of 1736.37 cm -1 and 1281.86 cm -1 , respectively. There are little observable traces of the lignin and hemicellulose bonds in the Figure 1 concluded that these weak components that held the bonds of MSSF has been drastically minimized and the cellulosic content in the composition of MSSF has improved after modification with NaOH as justified by works in elsewhere (41)(42)(43)(44) . Figure 2 captures the effect of alkali treatment on cellulose content of MSSF.…”

Background/Objectives: The minimization of unnecessary components from agro-waste is essential for performance and conversion into useful products in domestic and industrial utilization. The need for removal of these unwanted components is important to boost the strength of the agro-waste for its effectiveness as additive in agro-based polymer composite production as new engineering material for structural purpose. This investigation entailed the influence of NaOH concentration and soaking time on the key compositional content of novel mango seed shell fiber (MSSF). Methods/findings: The MSSF was treated with NaOH solution at 2.5, 5, 7.5 wt % concentration and soaking time of 2-6 hr. The compositions of MSSF were obtained for the treated and untreated sample by gravimetric method. The pure and NaOH treated MSSF were analyzed instrumentally employing Fourier transform infrared (FTIR) spectrometer to show the functionality of some substances present. From this result, the optimum composition of MSSF was observed at 5 % NaOH concentration and 4 hr soaking time. The maximum composition at this condition improved than the crude MSSF by 71.33% cellulose content, while the hemicelluloses and lignin content removal was lower than the raw fiber by 91.75 and 98.84%, respectively. Application: The results at this optimum treatment of MSSF composition can be recommended for agro-based polymer composite in indoor application.

“…Improved interaction between matrix and reinforcement can be enhanced via chemical treatment to selectively depreciate the amount of the hemicellulose and lignin while improving the rough surface of the fibres. This treatment modifies the hydrophilic nature of the fibre to ensure good adhesion with the matrix which is highly hydrophilic [ 33 ]. Yam peel as shown in Table 2 contains compounds such as SiO 2 and also Fe 2 O 3 usually regarded as good reinforcers with potential of improving mechanical properties of the matrix material.…”

Polypropylene composites reinforced with coir fibre and yam peel particulate were produced using compression moulding machine. Treated and untreated coir fibres were used; 1.5 M NaOH was used for the treated coir fibres. Yam peel was grouped into two, treated and untreated; the treated was modified using 1 M solution of NaOH and HCl in the proportion of 30% and 70%, respectively. The yam peel which was sun-dried for 14 days was pulverized and sieved to −45 µm. Samples were developed using treated and untreated reinforcements (TCF/YPP and UCF/YPP) at constant coir fibre proportion (15%) and varied amount of yam peel particulate (2, 4, 6, and 8 wt.%). The hybrid composite samples developed were probed for mechanical properties and thermal and wear behaviour. The level of particles agglomeration at the fibre-matrix interface was examined using scanning electron microscope. The results show that sample reinforced with treated 4 wt.% coir fibre and yam peel particulate had optimum mechanical properties. However, the thermal conductivity of composite samples increased with fibre addition. All composite samples developed had better resistance to abrasion when compared to the control sample.

“…As revealed in Table 3 , untreated jute fiber is made up of 57.45 % cellulose, 25.32 % hemicellulose, 15.41 % lignin and other constituent in proportion of 1.872 %. Alkali treatment afforded the fiber led to a decrease in lignin, hemicellulose, and other constituent [ 43 ] as shown in Table 3 and Figure 3 (a) and (b) respectively. It is noteworthy to mention the increase in the cellulose present in jute fiber, this leads to increase in cellulose present on fiber surface ready for contact with the matrix and hence, interfacial adhesion is improved [ 44 , 45 ].…”

This study evaluates the effect of treated and untreated jute fiber/eggshell particulate reinforced cement-paper matrix composites for ceiling board application. Treated jute fiber (TJF) was obtained by immersing untreated jute fiber (UJF) into 1.25 M sodium hydroxide (NaOH) solution in a shaker water bath maintained at 40 °C for 4 h. Eggshells (ESP) were pulverized and sieved to -75μm. Samples were prepared by varying the fiber volume fraction from 0.5 to 2.5 wt.% in the composites. While other constituents such as the binder (cement) and eggshell were kept constant. An hydraulic press cold compaction molder was utilized in the production of the hybrid composites in a predetermined mix ratio designed based on previous research. The samples produced were cured for 7 and 14 days, then sundried for 36 h. The physical, thermal, mechanical and wear behaviour of the produced composites were evaluated while the surface morphology of the fractured splitting tensile samples were analyzed. The result reveals that TJF/ESP hybrid composites had better performance than UJF/ESP hybrid composites in most of the tests carried out. Increase in the number of curing days was found to also enhance the properties of the composite produced in majority of the test evaluated. The 0.5 wt.% UJF/ESP gave the least performance of all the composites developed. While 2.5 wt. % TJF/ESP showed an optimum properties among the composites tested. When compared with standard, it is concluded that the hybrid composites developed can be suitable for ceiling boards and also find possible application in wall partitioning.
