“…It is worth noting that better mechanical properties were reported in hybrid composites than unhybridized cattail/polyester composites. is reveals a positive hybridisation effect on cattail fibres [13] and can be attributed to better dispersion of fibres in the hybrid composites compared to those fabricated from 100% cattail fibres [29].…”

“…Several researchers have investigated the effect of hybridising natural fibres such as sisal, jute, hemp, coir, and cattail on polymer matrices and how they improve the mechanical properties of the resultant polymer composites. In one of the pioneer studies, Bajwa et al [13] evaluated a hypothesized use of cattail as a potential cellulosic raw material for the manufacture of commercial composite panels (particleboards). In their study, low-density particleboards with varying proportions of cattail and wheat straw mixed with 3% methylene diphenyl diisocyanate resin (pMDI) had better mechanical properties than the individual fibres used singly.…”

Due to environmental and energy conservation concerns, a thrust towards low-cost lightweight materials has resulted in renewed interest in the development of sustainable materials that can replace nonbiodegradable and environmentally unfriendly materials in reinforced composites. In this study, mechanical properties of a hybrid composite consisting of polyester resin reinforced with a blend of sisal and cattail fibres were evaluated. The composite was fabricated using a hand lay-up technique at varying hybrid fibre weight fractions (5 to 25 wt%) while maintaining a constant fibre blend ratio of 50/50. Composites were also prepared at a constant fibre weight fraction of 20% while varying the fibre blend ratio between 0 and 100%. Fabricated composites were then characterised in terms of flexural, tensile, compressive, and impact strengths following ASTM and ISO standards. Results showed that, at a constant fibre blend ratio of 50/50, there was increase in the mechanical properties as the fibre weight fraction increased from 5 to 20%. At a constant fibre weight fraction (20%), a positive improvement in flexural, tensile, and compressive properties was registered as the fibre blend ratio varied between 0 and 75% with optimal values at a sisal/cattail ratio of 75/25. The current study suggests that blending sisal and cattail fibres for production of polyester composites yields hybrid composites with enhanced mechanical properties.

“…However, the two mercerization treatments and the hot water treatment at 125 °C were the more effective at increasing the AC. The hot water treatment process generally removes volatile compounds and the waxy coating on plant fibers, making the cellulosic fibers more accessible to the medium (Bajwa et al 2015). Perhaps the hot water treatment at 80 °C was not hot enough to effectively remove the waxy coating from the fiber and limited its exposure to the media.…”

Most plant fibers are good sorbents of oil; however, synthetic sorbents have a much higher sorption capacity (SC) than plant fibers. This study evaluated the effect of fiber treatments, specifically hot-water treatment and mercerization, on the absorption characteristics of selected plant fibers. Five common plant fibers-corn residues, soybean residues, cotton burr and stem (CBS), cattail, and oak-were evaluated for their absorption characteristics in crude oil, motor oil, deionized (DO) water, and a 80:20 mix of DO water. The fiber treatments included ground fiber (control), hotwater treatment at 80 °C for 4 h and 125 °C for 4 h, mercerization at room temp for 48 h, and mercerization at 300 °C for 1 h. The absorption capacity (AC) varied with fiber type, absorption medium, and fiber treatment. Mercerization at 300 °C increased the water absorption of soybean residue up to 8 g/g. Mercerization at room temperature and the hot-water treatment at 125 °C increased the crude oil absorption capacity. After certain treatments, the crude oil absorption capacity of CBS and corn fibers increased over 5 g/g, and the motor oil absorption capacity of cattail, corn, and soybean also increased to 4 to 5 g/g.

“…Although Typha is available abundantly in nature, its potential is still underutilized compared to other natural fibers [8]. From the previous reports it is well known that the Typha fiber reinforced composites have many advantages, such as good bending properties [9], being lightweight [10], having good mechanical strength, are low density and can be renewed [11]. However, so far there is no report about Typha fiber reinforcing epoxy composite.…”

Interfacial Compatibility Evaluation on the Fiber Treatment in the Typha Fiber Reinforced Epoxy Composites and Their Effect on the Chemical and Mechanical Properties

Natural fiber composites have been widely used for various applications such as automotive components, aircraft components and sports equipment. Among the natural fibers Typha spp have gained considerable attention to replace synthetic fibers due to their unique nature. The untreated and alkali-treated fibers treated in different durations were dried under the sun for 4 h prior to the fabrication of Typha fiber reinforced epoxy composites. The chemical structure and crystallinity index of composites were examined via FT-IR and XRD respectively. The tensile, flexural and impact tests were conducted to investigate the effect of the alkali treated Typha fibers on the epoxy composite. From the microscopy analysis, it was observed that the fracture mechanism of the composite was due to the fiber and matrix debonding, fiber pull out from the matrix, and fiber damage. The tensile, flexural and impact strength of the Typha fiber reinforced epoxy composite were increased after 5% alkaline immersion compared to untreated Typha fiber composite. From these results, it can be concluded that the alkali treatment on Typha fiber could improve the interfacial compatibility between epoxy resin and Typha fiber, which resulted in the better mechanical properties and made the composite more hydrophobic. So far there is no comprehensive report about Typha fiber reinforcing epoxy composite, investigating the effect of the alkali treatment duration on the interfacial compatibility, and their effect on chemical and mechanical of Typha fiber reinforced composite, which plays a vital role to provide the overall mechanical performance to the composite.
