“…An increase in composite NI strength with increasing fiber length was reported by most length related studies (Garkhail et al, 2000;Jayaraman, 2003;Mohanty et al, 2004a;Beg and Pickering, 2008;Pailoor et al, 2018). It has been pointed out that an increase in the fiber length could lead to an improved stress transfer and reduction of high stress concentration points at fiber ends (Beg and Pickering, 2008).…”

“…None of the composite samples exhibited higher impact performance than the unreinforced reference PP sample. Pailoor et al (2018) studied the effect of changing the fiber length of the input jute fibers being compounded in a twin screw extruder. Fiber input was either "continuous" jute yarn or the same yarn which had been pre-chopped to 2 mm length.…”

Many academic studies continue to conclude that natural fiber reinforced thermoplastic composites (NFTCs) have some potential to compete with mineral/inorganic fiber and filler reinforced composites in certain applications due to their distinctive characteristics. NFTCs are often presented as a more environmentally friendly product which may, in some cases, offer useful levels of specific strength and stiffness with an overall reduced carbon footprint. However, from an end-use composite performance viewpoint, issues with impact resistance (notched and un-notched) continue to hold back the large-scale implementation of these composites. This paper presents a review of the recent work on impact properties of NFTCs, analysing the effects of fundamental composite parameters and potential routes to improvement.

“…The jute fibers and PLA were blended using an IM machine before the specimen was prepared using SHJ-20 twin-screw extruder. Pailoor et al examined the effect of chopped/continuous fiber, coupling agent and fiber ratio on the jute fiber/PP composites (Pailoor et al, 2019). Chopped jute fiber of length 1-2 mm and PP pellets along with MAPP was fed into a STEER Omega-40 twin-screw co-rotating extruder to prepare the compounded pellets.…”

For the last couple of decades, researchers have been trying to explore eco-friendly materials which would significantly reduce the dependency on synthetic fibers and their composites. Natural fiber-based composites possess several excellent properties. They are biodegradable, non-abrasive, low cost, and lower density, which led to the growing interest in using these materials in industrial applications. However, the properties of composite materials depend on the chemical treatment of the fiber, matrix combination, and fabrication process. This study gives a bibliographic review on bio-composites specially fabricated by the injection-molding method. Technical information of injection-molded natural fiber reinforcement-based composites, especially their type and compounding process prior to molding, are discussed. A wide variety of injection-molding machines was used by the researchers for the composite manufacturing. Injection-molded composites contain natural fiber, including hemp, jute, sisal, flax, abaca, rice husk, kenaf, bamboo, and some miscellaneous kinds of fibers, are considered in this study.

Natural fibre-reinforced polymer composites are increasingly replacing commercial composite materials. The limitations of conventional composites materials are overcome by green composites, which are easily available, more eco-friendly and less toxic. In the current scenario, green composites are emerging in the field of material science that involves improving their physical, mechanical and thermal properties. The poor interfacial adhesion and surface incompatibility between natural fibre and biodegradable polymers lead to reduced physico-mechanical properties. In order to overcome this issue, physical and chemical modification methodologies of the natural fibre and polymer matrix are employed, among which the addition of coupling agents has a critical contribution. This paper compiles several recent research works in the utilization of coupling agents such as silane, maleic anhydride, isocyanate, triazine, etc., with the various combinations of natural fibres and polymers. In addition to this, the extents of influence of coupling agents on the characteristics of the natural fibre reinforced composite materials are also reported. This gives an overview for the future researchers to identify the gap in the field of green composite materials and novel coupling agents for different natural fibre/polymer matrix combination.
