“…The strength and stiffness of polymer-matrix composites would increase with an increase in the fibre content (%) available as reinforcements. The diameter of the Topas fibres lies in between 23.82 and 282.34 μm, which is comparatively lower than other bast fibres like hemp (25-500 μm) and flax (40-600 μm) [25]. Further, the density of canola is lower than other bast fibres like flax and hemp.…”

“…In the quest for developing low density and green material-based composites, researchers often use hollow fibres to reduce the overall weight of the composite structures [22,23]. Kumar et al [4] recently designed a natural fibre-based light-weight high-strength composite for aerospace and automotive application using hollow glass microspheres.…”

This study aims to reinforce wood particle composite structures with novel lightweight hollow Topas canola fibres (Brassica napus L.). The feasibility of methyl ethyl ketone peroxide (MEKP)-cured hybrid composite structures of canola and wood biomass is demonstrated in the current study. By employing a facile fabrication technique under ambient conditions, different hybrid canola composite structures are fabricated with randomly distributed fibre polymer reinforcements and synthetic resin matrix. Hybridization process involves the incorporation of hollow canola fibres and wood biomass to yield better mechanical performance including breaking strength, flexural rigidity, and strength to weight ratio. The produced hybrid composites can outperform pristine heavyweight wood composites, exhibiting superior flexural strength up to 6.4 (± 2.5) Pa-m 4 of flexural rigidity and 728.35 (± 242) N of breaking load with the extra feature of lower wood content. The hybrid composite structure exhibited a modulus of elasticity up to 8.76 GPa exhibiting ~ 6% higher stiffness than the pristine wood composites. Also, the diameter (84.30 ± 38.04 μm) of the canola fibres is coarse enough for composite fabrication. This confirms the effective contribution of canola fibres to the flexural properties of hybrid composite structures. Further, the two-parameter Weibull mathematical model is applied for failure (R 2 ≥ 0.92) and reliability (R 2 ≥ 0.93) analysis. The constructed probability distribution curves predict probabilistic composite failures against ranges of bending deflection. The intrinsic hollow interior of the novel canola fibre opens new doors for self-healing natural fibre-based composite fabrication. Such lightweight composite structures can find promising applications in technical textiles, including the interior panels of automotive, aerospace, furniture, and the construction industry.

“…The high strength PET fibers are repeatedly processed with combing and scattering to form staple fibers, and then made into nonwoven fabrics. Based on the test results, the tensile and tearing strength of the PET fibers are comparable to those of the embossing fibers, which indicates that the recycling has effective value [24,25,26].…”

Mechanical and Static Stab Resistant Properties of Hybrid-Fabric Fibrous Planks: Manufacturing Process of Nonwoven Fabrics Made of Recycled Fibers

With the development of technology, fibers and textiles are no longer exclusive for the use of clothing and decoration. Protective products made of high-strength and high-modulus fibers have been commonly used in different fields. When exceeding the service life, the protective products also need to be replaced. This study proposes a highly efficient recycling and manufacturing design to create more added values for the waste materials. With a premise of minimized damage to fibers, the recycled selvage made of high strength PET fibers are reclaimed to yield high performance staple fibers at a low production cost. A large amount of recycled fibers are made into matrices with an attempt to decrease the consumption of new materials, while the combination of diverse plain woven fabrics reinforces hybrid-fabric fibrous planks. First, with the aid of machines, recycled high strength PET fibers are processed into staple fibers. Using a nonwoven process, low melting point polyester (LMPET) fibers and PET staple fibers are made into PET matrices. Next, the matrices and different woven fabrics are combined in order to form hybrid-fabric fibrous planks. The test results indicate that both of the PET matrices and fibrous planks have good mechanical properties. In particular, the fibrous planks yield diverse stab resistances from nonwoven and woven fabrics, and thus have greater stab performance.

“…The choice of natural fibres for making composites are based on its availability in the particular country [7].In Asian countries hemp, kenaf, jute and sisal are available in plenty whereas flax is available in Europe and Harakeke fibre is available in New Zealand [7]. It was reported that jute and hollow conjugated polyester reinforced non woven composite of 50:50 ratio is suitable for structural materials of building [6] furniture making [8] outdoor & indoor insulation applications [9].Longer fibres can take up higher loads but too longer fibres may entangle during mixing and result in lower reinforcement [14][15][16].The length to diameter ratio of the fibre affects the mechanical properties. The fibre length must be higher than the critical length for the fibre to be broken during tensile load application in a composite [12].For efficient reinforcement fibre length must be much higher.…”

Renewable natural fibres like kenaf can be used to produce composites as replacement to plastic boards in household and industrial applications. The objective of this study is to optimise the process parameters for compression moulding of kenaf polypropylene composite to get maximum tensile, flexural and impact strength values for three different blend ratios. Three levels of temperature (160oC, 180oC and 200 oC), compression pressure (7, 9 and 11 Mpa) and time of application (10,20 and 30 min ) for producing kenaf/ polypropylene blend ratios of 50:50, 65:35 and 80:20 have been used. The samples were produced through carding for web formation, needle punching for non woven making and finally in compression moulding machine for boards making. All the composite boards were analysed for tensile, flexural and impact strength. The tensile and flexural strengths have positive correlations with time and temperature and contact pressure in all the blend ratios kenaf / polypropylene. The impact strength has positive correlation with time, temperature whereas it has negative correlation with contact pressure in all the blend ratios. The highest tensile strength and flexural strength is achieved with 65:35 kenaf / polypropylene blend at 200 o C temperature, 11Mpa pressure and 10 minutes duration in compression moulding machine. The highest Impact strength is achieved with 80:20 blends at 180 o C, 7 Mpa pressure and 30 minutes duration. The tensile and flexural strength is the highest at the blend ratio of 65:35 whereas the Impact strength increases with the increase kenaf content up to 80%..
