“…Single and twin extruder have a different processing temperature range, process parameters, and screw designs. Process parameters influence mechanical and thermal properties [ 269 ]. Process parameters such as high pressure and high temperature damage natural fibers, albeit resulting in a better aspect ratio but at the cost of mechanical properties such as high porosity [ 270 ].…”

Increased environmental concerns and global warming have diverted focus from eco-friendly bio-composites. Naturals fibers are abundant and have low harvesting costs with adequate mechanical properties. Hazards of synthetic fibers, recycling issues, and toxic byproducts are the main driving factors in the research and development of bio-composites. Bio-composites are degradable, renewable, non-abrasive, and non-toxic, with comparable properties to those of synthetic fiber composites and used in many applications in various fields. A detailed analysis is carried out in this review paper to discuss developments in bio-composites. The review covers structure, morphology, and modifications of fiber, mechanical properties, degradable matrix materials, applications, and limitations of bio-composites. Some of the key sectors employing bio-composites are the construction, automobile, and packaging industries. Furthermore, bio-composites are used in the field of medicine and cosmetics.

Date palm fibres are one of the most available natural fibres in North Africa and the Middle East. A significant amount of date palm fibres biomass is wasted annually and only limited amounts are used in low value products. In this study, tensile and low-velocity impact response of biodegradable lignocellulosic biomass reinforced polycaprolactone (PCL) biocomposites are reported. Two different types of laminates reinforced with date palm fibre obtained from agriculture waste were manufactured by an extrusion process. The influence of processing parameters, such as screw rotation speed on the tensile and low velocity impact damage characteristics have been investigated. The tensile strength increased for neat PCL from 19 MPa to 25 MPa with 28 wt.% reinforcement of date palm fibres. Similarly, the tensile modulus for neat PCL was increased from 140 MPa to 282 MPa upon reinforcement. The screw rotation speed showed a moderate effect on palm fibre morphologies, and slight effect on tensile properties of the biocomposites. Specimens with lower incident energy of 25 J achieved better impact resistance compared to that of 50 J. The impact damage of biocomposites analysed through electron microscopy on the fractured surface showed various modes of damage. The biocomposites developed in this work can be used as an economically and environmentally attractive alternative materials for lightweight applications in automotive and marine sectors.

“…In this regard, flax fibers show a favorable combination of properties that make them a material of choice to reinforce polymers, such as their wide availability throughout the world, their morphology characterized by significant length (around 2-5 cm) with thick secondary walls (5-15 µm), good mechanical properties caused by a small microfibrillar angle, and high cellulose content and low density [2]. Therefore, flax fibers have Molecules 2020, 25, 438; doi:10.3390/molecules25030438 www.mdpi.com/journal/molecules been extensively investigated over the last twenty years [3][4][5], and two issues have been highlighted that still prevent their full exploitation as reinforcement in composite materials, i.e., the variability in properties and the poor interfacial adhesion with most polymer matrices. As regards the first issue, recent studies have demonstrated that tensile properties of flax fibers are not significantly affected over time irrespective of the fiber yield and variety and that the scattering in the specific mechanical properties lies in the same range of glass fibers [6].…”

Environmentally Friendly Surface Modification Treatment of Flax Fibers by Supercritical Carbon Dioxide

et al. 2020

The present work investigates the effects of an environmentally friendly treatment based on supercritical carbon dioxide (scCO2) on the interfacial adhesion of flax fibers with thermoset matrices. In particular, the influence of this green treatment on the mechanical (by single yarn tensile test), thermal (by TGA), and chemical (by FT-IR) properties of commercially available flax yarns was preliminary addressed. Results showed that scCO2 can significantly modify the biochemical composition of flax fibers, by selectively removing lignin and hemicellulose, without altering their thermal stability and, most importantly, their mechanical properties. Single yarn fragmentation test results highlighted an increased interfacial adhesion after scCO2 treatment, especially for the vinylester matrix, in terms of reduced debonding and critical fragment length values compared to the untreated yarns by 18.9% and 15.1%, respectively. The treatment was less effective for epoxy matrix, for which debonding and critical fragment length values were reduced to a lesser extent, by 3.4% and 3.7%, respectively.
