“…These composites are being used as alternatives to glass fiber polymers for designing car panels. 93 As well, in our previously reported study, we demonstrated the use of hemp fiber composite as plant growth media for hydroponics 94 (one type of soilless farming). 45 These aforementioned examples illustrate that hemp fiber composites have an exciting prospect due to their diverse and large arrays of practical applications.…”

In this paper, an environmentally friendly fabrication process was reported to valorize hemp fibers into biocomposites through a pectin-based crosslinking reaction. In this water-based chemical approach, the hemp fibers were crosslinked via a transesterification process between pectin and lignin present in hemp fibers to produce hemp fiber composites in a one-step process. Our green process was advantageous over conventional processes that rely on the use of petroleum-based organic solvents and high reaction temperatures because water was used as the reaction solvent with a mild reaction temperature (70 C). Additionally, to further optimize this biocomposite fabrication process, one-factor analysis of variance study was carried out for investigating the main and interaction effects of the mass ratios of pectin to hemp fiber (1:5, 2:5, 3:5, 4:5, and 5:5) on the compressive strength and bulk density of the hemp fiber composite materials. In addition, the fabrication process was explored at different pH values to probe its versatility. The compressive strength of the assynthesized hemp fiber composite materials was observed to be dependent on the pH of the reaction conditions, indirectly confirming the formation of ester bonds between pectin and the lignin of hemp fibers via transesterification.

“…Currently, the sustainable use of agricultural waste to minimize environmental burdens while maintaining ecosystem sustainability is increasing rapidly. Many types of fiber’s natural sources have been intensively studied concerning their application in various fields and industries [ 7 , 8 ]. However, only a small number of publications have discussed extensively the physical, mechanical, and thermal performances of oil palm empty fruit bunches (OPEFB) [ 9 , 10 , 11 ].…”

“…Alternatively, a recent study finds that the finer OPEFB particles have increased composite tensile strength and thermal properties [ 13 ]. This finding placed OPEFB amongst the lists of potential composites since it shared almost similar tensile and modulus properties to coir, jute, sisal, hemp, and ramie, which have already been integrated into automotive applications [ 8 , 13 ]. OPEFB appears to have great potential to be applied for non-structural material alternatives.…”

The sustainable use of agricultural waste to generate valuable products while minimizing environmental burdens is increasing rapidly. Multiple sources of fibers have been intensively studied concerning their application in various fields and industries. However, few publications have extensively discussed the property’s performance of oil palm empty fruit bunches (OPEFB) composites. With main properties similar to composites currently listed for industrial applications, OPEFB is worth listing as a potential composite for industrial applications and non-structural material alternatives. OPEFB-reinforced polymer composites are expected to be applied to automotive interior parts. This study aims to determine the effect of adding zinc oxide (ZnO) and polyurethane on OPEFB-reinforced polymer composites for automotive interior parts. This composite was produced using the hand lay-up method with 70% resin, 15% OPEFB fiber, 15% polyurethane as a blowing agent, and four variations of ZnO at 5%, 10%, 15%, and 20%. The OPEFB particle sizes are 40, 60, 80, and 100, respectively. The composite was examined to determine mechanical, morphology, chemical, and thermal characteristics. It was observed that the addition of 20% ZnO caused ZnO agglomeration, weakening the interfacial bond between OPEFB particles, polyester, polyurethane, and ZnO filler. Overall, the results showed that adding ZnO and polyurethane to the composite increased tensile, compressive, flexural, and impact strength, as well as thermal stability with more significant values up to 160%, 225%, 100%, 100%, and 4.3%, respectively. This result depicted that the best composition was specimens with 15% ZnO and 149 microns OPEFB fibers particle size. It is considered a promising candidate to be applied in automotive interior components.

“…For PLLA braided stents, the strength and toughness of the monofilaments are required. Although PLLA material has high strength and stiffness, the inherent brittleness still limits its development. , To enhance the toughness of PLLA, various methods have been used such as blending , and copolymerizing flexible polymers. PLLA blending with flexible polymers has been proven to be an efficient and economical method .…”

Key Factors of Mechanical Strength and Toughness in Oriented Poly(l-lactic acid) Monofilaments for a Bioresorbable Self-Expanding Stent

et al. 2022

The investigation of the strength and toughness of poly(L-lactic acid) (PLLA) monofilaments is essential as the fundamental element of a biodegradable braided stent. However, the determining factor remains poorly addressed with respect to influencing the mechanical behavior of PLLA monofilaments. In this work, the electron beam (EB) with different radiation doses was utilized to sterilize PLLA monofilaments. Properties of the monofilaments, including the breaking strength, elongation at break, molecular weight, orientation, and microstructure of the fracture, were characterized. Results showed that a random chain scission of PLLA resulting from EB during this process could cause the decrease in molecular weight, which led to the decline in breaking strength. Meanwhile, the irradiated monofilaments were found to have almost the same elongation at break below a dose of 30 kGy and declined by 71.41% up to a dose of 48 kGy. It was also found that the ductile fracture connection of the monofilament translated to the brittle fracture by comparing the microstructure without and with sterilization. These phenomena could originate from the destruction of the long molecular chains connecting the crystal plates into shorter ones by radiation. PLLA monofilaments with 0, 30, and 48 kGy were used to braid carotid stents. Compared with a carotid Wallstent, the PLLA stent can better provide radial supporting to the carotid lesion. This study provides preliminary experimental references to evaluate and predict the mechanical performance of PLLA braided stents.
