“…PFRPs are go-to-solutions for automotive interior components, providing opportunities in (a) weight reduction due to good specific properties ( Fig. 1), (b) cost saving, and (c) end-of-life disposal by incineration (Koronis et al 2013;Mougin et al 2009) 2. Plant fibres are abundant and low cost, and consequently PFRPs products (e.g.…”

The drive towards sustainability, even in materials technologies, has fuelled an increasing interest in bio-based composites. Cellulosic fibres, such as flax and jute, are being considered as alternatives to technical synthetic fibres, such as glass, as reinforcements in fibre reinforced polymer composites for a wide range of applications. A critical bottleneck in the advancement of plant fibre composites (PFRPs) is our current inability to predict PFRP properties from data on fibre properties. This is highly desirable in the cost-and time-effective development and design of optimised PFRP materials with reliable behaviour. This study, alongside limited other studies in literature, have found that the experimentally determined (through single fibre tests) fibre properties are significantly different from the predicted ('backcalculated' using the popular rule-of-mixtures) fibre properties for plant fibres. In this note, we explore potential sources of the observed discrepancy and identify the more likely origins relating to both measurement and errors in predictions based on the rule-of-mixtures. The explored content in this discussion facilitates the design of a future investigation to (1) identify the sensitivity of the discrepancy between measured and predicted fibre properties to the various potential origins, (2) form a unified hypothesis on the observed phenomenon, and (3) determine whether the rule-of-mixtures model (in specific cases) can be improved and may be able to predict properties precisely.

Treated and untreated woven century fiber (CF) composites are investigated for evaluating their flexural, tensile, and impact strengths, Barcol hardness, glass transition temperature, thermal resistance, and water absorption properties. Scanning electron microscopy study revealed a brittle fracture for treated fiber composite, while significant fiber pull-out is observed for the untreated fiber composite. Higher tensile and hardness properties, higher glass transition and thermal decomposition temperatures, and low water absorption properties are obtained for alkaline-treated composites. Enhanced interface bonding due to improved adhesion has helped in the formation of covalent bonds at the fiber–matrix interface, resulting in superior tensile, thermal, and water absorption properties of the treated fiber composite. Flexural and impact properties are higher for untreated fiber composite. This is due to the weak fiber–matrix interface and a differential strain in fiber and matrix. The weak interface has provided an energy absorbing mechanism and enhanced the impact energy absorption capacity. The tensile strength of CF composite is very much comparable with that of sisal fiber composite. The tensile and flexural properties are higher for the woven CF composites than those of short CF composites. But the impact properties are superior for short fiber composites compared to the woven fiber composites. Increased number of interfaces for the short fiber composites has contributed for the cushioning effect and an enhanced energy absorbing mechanism. Water absorption properties have improved for the treated fiber composites due to formation of a strong interface.
