“…It can also be seen that the hybrid composites exhibited higher stiffness propensity with the UPE matrix system (CS #4) compared to the VER resin (CS # 5). Surprisingly, this reported MOEs of the canola-wood composites were superior to the reported MOE performances of wood-flax (2.72 GPa), wood-hemp (2.06 GPa), or shive-flax (4.02 GPa) structures [45]. The behavior of the improved flexural stiffness with a lower wood fraction of the hybrid composites is similar to that of the flexural rigidity.…”

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.

“…However, it was characterized by high vapor permeability and resistance to biological corrosion due to high pH value. Metakaolin was a highly reactive pozzolanic material, which was formed in the kaoline clay calcination process under controlled temperature conditions of around 600-850 • C. Its main ingredient was hydrated aluminum silicate Al 2 Si 2 O 5 (OH) 4 . This additive has been used in other studies of the hemp-lime composite [35].…”

“…Scientific research is currently being conducted on the different natural materials that could be utilized as building materials. The examples include cut sunflower stalk mixed with gypsum binder [2] as insulation board, sisal fibers [3] as scattered reinforcement, flax [4] as an element of chipboards, hemp fibers and shives [5] in mortars, flax or hemp fibers as thermal insulation [6], but also ligneous parts of stalks cut into shives of hemp used as aggregate for the composites based on lime binder [7,8].…”

The use of waste plants in the production of building materials is consistent with the principles of sustainable development. One of the ideas involves using hemp shives as an aggregate for the production of a composite used as a filling of the timber frame construction of the walls. The most important disadvantage of using the building materials based on organic components is their susceptibility to the water influence. The wall material is exposed to rising groundwater. The research part of the paper presented the preparation method and the investigation of the hemp-perlite-lime composites. Flexural and compressive strength, apparent density, total porosity, thermal conductivity, and mass absorptivity were examined. The main research part pertained to the analysis of capillary uptake occurrence in the composites, being the important phenomenon present in the external walls. The study on this phenomenon was carried out using the technique of indirect moisture evaluation—Time Domain Reflectometry (TDR). The indirect readouts were additionally verified with the traditional evaluation using the gravimetric method based on the PN-EN 1925 standard. The study proved that the tested composites were characterized by low apparent density, thermal conductivity, strength parameters, high total porosity, and mass absorptivity. The partial replacement of hemp shives by expanded perlite had a beneficial effect on the tested properties of composites.

The increase in awareness of the damage caused by synthetic materials on the environment has led to the development of eco-friendly materials. The researchers have shown a lot of interest in developing such materials which can replace the synthetic materials. As a result, there is an increase in demand for commercial use of the natural fiber-based composites in recent years for various industrial sectors. Natural fibers are sustainable materials which are easily available in nature and have advantages like low-cost, lightweight, renewability, biodegradability, and high specific properties. The sustainability of the natural fiber-based composite materials has led to upsurge its applications in various manufacturing sectors. In this paper, we have reviewed the different sources of natural fibers, their properties, modification of natural fibers, the effect of treatments on natural fibers, etc. We also summarize the major applications of natural fibers and their effective use as reinforcement for polymer composite materials.
