“…The samples consist mainly of alcohol, phenol, ester, ketone, and alkene, consistent with the composition of the main components of biomass: cellulose, hemicellulose, lignin, and pectin. [37,48] Interestingly, both pine and coconut flour exhibit strong absorption near 1050 cm À1 , consistent with C O stretching in a primary alcohol contained in cellulose. [37,49] However, after pyrolysis of pine and coconut flour, absorption near 1050 and 3400 cm À1 is reduced, suggesting that primary alcohol or ethanol was consumed or converted during pyrolysis.…”

In recent years, automotive manufacturers have increased their use of natural fiber composites to reduce vehicle weight and improve carbon footprint. However, natural fibers have lower thermal stability than many synthetic fiber alternatives, limiting their application to low‐processing temperature polymers and low‐temperature automotive environments. Pyrolysis of biomass yields a porous substance called biocarbon, which has superior thermal performance and hydrophobicity than biomass. This study evaluated the effects of biocarbon pyrolysis conditions and biomass source on the properties of biocarbon powders and the performance of biocarbon as a reinforcing agent in thermoplastic composites. Hybrid biocarbon‐glass fiber polyamide‐6 composites were generated with varying loading level and biocarbon type. Composites were evaluated in terms of mechanical (tensile and impact), morphological (scanning electron microscope), and thermal performance (thermal gravimetric analysis [TGA] and differential scanning calorimetry [DSC]); the chemical characteristics (X‐ray photoelectron spectroscopy and Fourier transform infrared) and thermal performance (TGA and DSC) of biocarbon powders were also determined. A 10% increase in the loading level of biocarbon resulted in a 7%–10% improvement in composite strength. Biomass source affected the thermal stability of a biocarbon powder. Coconut‐based biocarbon composites exhibited thermal performance comparable to materials currently used in automotive fan‐and‐shroud applications, suggesting that biocarbon composites have the potential for use as low‐density, high‐temperature automotive materials.

“…The other lengths of fiber used for the study were 3, 5 and 7 mm. Sugiman et al (2019) investigated the effect of fiber length on the mechanical and water absorption properties of composite made of bamboo fiber/polystyrene-modified unsaturated polyester resin matrix. The range of fiber length used in the study was varied from 2.5 mm to 15 mm and fiber volume fraction at 0.2, 0.25 and 0.3.…”

Purpose The study aims to review the literatures on the effect of fiber length on the mechanical response of natural fiber composite will help the researchers to know about the perspective of the various natural fibers in making of composite concerning fiber length. The review summarized the work of the other researchers, thereby unambiguously précised suitability of a specific natural fiber for a matrix in use. Thus, one can identify the use of the same fibers–matrix combination to obtain composites with different properties with the control of fiber/matrix interface. Design/methodology/approach The review work proposes a new kind of diagrammatic representation that expresses the influence of fiber length. This work has not been explored before in this specific format. The chronology of work may help to select natural fibers for use in composites for a specific matrix. Findings The length of the fiber perception in terms of “critical” length decides the need for pre-treatment process of natural fiber to improve shear stress at the interface for various matrices. Originality/value The current review paper attempts to shed light on the association between the fiber length of natural fiber and the mechanical response of natural fiber composite. Moreover, it probes the concepts of critical fiber length as a persuadable factor.

“…Several factors affect the performance of the physical properties of CB, for example, various lengths of the fibre (Akasah et al, 2019). Research conducted by Sugiman et al (2019) found that the fibre length influenced the workability and increasing impact strength of cement board. Heterogeneous fibre length can improve various mechanical properties of CB as compared to only one larger fibre size.…”

In a cement board (CB) composite, fibres reinforce the board. It is because the length of the fibres significantly impacts the strength of the CB composite. Nonetheless, the physical properties of the CB are also an important aspect when dealing with the quality control of the final product. This study investigates the effects of various fibre lengths in CB fabrication on its physical properties, including the cement-hydration rate, tensile strength, density stability and thickness swelling (TS). Oil palm empty fruit bunch (OPEFB) fibres at different lengths are used based on the mesh retained size of R7M, R14M, and R30M. The OPEFB-CB mixture used in this research is 3:1 (cement: fibre ratio), with a target density of 1,300 kg/m3. The sample is compressed using a 1000 psi cold-compression load to achieve the desired composite thickness of 12 mm. This research revealed that the longest fibres retained on the R7M mesh with an average length of 5 mm resulted in lower density and the highest TS value. Meanwhile, lower dimensional stability was achieved by OPEFB-CB composites using fibre that retained on the R14M and R30M, having an average length of 3 mm and 1 mm, respectively. Based on the results, the optimum fibre length recommended in the fabrication of OPEFB-CB composites is processed fibres retained on the R14M sieve with an average length of 3 mm. This recommendation is made based on the most stable density and lowest TS results achieved by the R14M retained fibres which is in the range of 1,231–1,309.4 kg/m3 and TS of 0.65 %.
