“…Before modification, DMF was used as a swelling agent and catalyst for KBF. The fiber cell wall swelled and exposed the OH groups on the surface of the cellulose, thereby allowing MA to react to form chemical bonds [ 44 , 49 ]. As the reaction time increases, more chemical bonds would have been formed between the OH groups and MA in cellulose.…”

The demand for natural fiber hybrid composites for various applications has increased, which is leading to more research being conducted on natural fiber hybrid composites due to their promising mechanical properties. However, the incompatibility of natural fiber with polymer matrix limits the performance of the natural fiber hybrid composite. In this research work, the mechanical properties and fiber-to-matrix interfacial adhesion were investigated. The efficiency of methyl methacrylate (MMA)-esterification treatments on composites’ final product performance was determined. The composite was prepared using the hand lay-up method with varying kenaf bast fiber (KBF) contents of 10, 15, 20, 25, 30, 35 (weight%) and hybridized with glass fiber (GF) at 5 and 10 (weight%). Unsaturated polyester (UPE) resin and methyl ethyl ketone peroxide (MEKP) were used as binders and catalysts, respectively. Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) were used to examine the effects of MMA-esterification treatment on tensile strength and morphology (tensile fracture and characterization of MMA-esterification treatment) of the composite fabricated. The tensile strength of MMA-treated reinforced UPE and hybrid composites are higher than that of untreated composites. As for MMA treatment, 90 min of treatment showed the highest weight percent gain (WPG) and tensile strength of KBF-reinforced UPE composites. It can be concluded that the esterification of MMA on the KBF can lead to better mechanical properties and adhesion between the KFB and the UPE matrix. This research provides a clear reference for developing hybrid natural fibers, thus contributing to the current field of knowledge related to GF composites, specifically in transportation diligences due to their properties of being lightweight, superior, and involving low production cost.

“…Striving to reduce environmental footprint, human society demonstrates ever increasing interest in sustainable development and the use of natural materials, and the composite industry is no exception. Application of biocomposites is currently one of urgent research topics in thermoplastic materials [ 265 , 266 , 267 , 268 , 269 , 270 ]. Broad introduction of such composites into everyday life will obviously require extensive study of their properties and characteristics.…”

Thermoplastic Pultrusion: A Review

et al. 2021

Pultrusion is one of the most efficient methods of producing polymer composite structures with a constant cross-section. Pultruded profiles are widely used in bridge construction, transportation industry, energy sector, and civil and architectural engineering. However, in spite of the many advantages thermoplastic composites have over the thermoset ones, the thermoplastic pultrusion market demonstrates significantly lower production volumes as compared to those of the thermoset one. Examining the thermoplastic pultrusion processes, raw materials, mechanical properties of thermoplastic composites, process simulation techniques, patents, and applications of thermoplastic pultrusion, this overview aims to analyze the existing gap between thermoset and thermoplastic pultrusions in order to promote the development of the latter one. Therefore, observing thermoplastic pultrusion from a new perspective, we intend to identify current shortcomings and issues, and to propose future research and application directions.

“…Furthermore, Ramesh et al (2017) described that composites containing nano-fibrillated fiber have higher flexural strength, higher flex-ural modulus and reduced fracture energy compared to composites reinforced with conventional fiber [21]. However, a study on PHA matrix composites stated that the main limitation of PHAs in processing are their thermal instability, and mixture of nanofillers would improve its thermal stability caused by the dispersed filler layers acting as a barrier to volatiles and oxygen produced during thermal decomposition of PHAs [58]. The degree of dispersion affects the thermal degradation of nano-composites because generation of local heat as a result of accumulation.…”

Petroleum-based synthetic polymers are mostly used for packaging materials for their advantageous features such as flexibility, lightness and transparency. However, the waste caused by the increasing usage has led to serious environmental impacts. There are many packaging products claimed as ‘green’ material in the market but, they are not fully from natural renewable resources. Most biocomposites materials comprised only either the matrix or fiber/filler from natural renewable resources, but still blended with another synthetic compound. Thus, green biocomposites which composed of fully biodegradable natural fibers and biopolymer matrix would be a great alternative. It can be naturally degraded and completely return to the environment safely after usage. The main shortcomings of biopolymer are their inadequate of mechanical and barrier properties in product application. Yet, the embedding reinforcing fibers or fillers would help in improving the final properties of the composites. The intention of this review is to present the latest development of green biocomposites research and its application for food packaging. It is also proposed to provide critical information that covers around properties of green biocomposites, types of available biopolymers and natural fibers, including their manufacturing techniques. Furthermore, the economic circumstances and forthcoming trend of these materials in food packaging industry would also be reviewed
