Over the last decade, the progressive application of natural fibres in polymer composites has had a major effect in alleviating environmental impacts. Recently, there is a growing interest in the development of green materials in a woven form by utilising natural fibres from lignocellulosic materials for many applications such as structural, non-structural composites, household utilities, automobile parts, aerospace components, flooring, and ballistic materials. Woven materials are one of the most promising materials for substituting or hybridising with synthetic polymeric materials in the production of natural fibre polymer composites (NFPCs). These woven materials are flexible, able to be tailored to the specific needs and have better mechanical properties due to their weaving structures. Seeing that the potential advantages of woven materials in the fabrication of NFPC, this paper presents a detailed review of studies related to woven materials. A variety of factors that influence the properties of the resultant woven NFRC such as yarn characteristics, fabric properties as well as manufacturing parameters were discussed. Past and current research efforts on the development of woven NFPCs from various polymer matrices including polypropylene, polylactic acid, epoxy and polyester and the properties of the resultant composites were also compiled. Last but not least, the applications, challenges, and prospects in the field also were highlighted.

“…Starch can be extracted from sugar palm trunk (Arenga Pinnata), a multipurpose material with several industrial uses, especially in plastic packaging. Sugar palm starch has been extensively used to produce bio-based starch films, and the results show that these carbohydrates are promising materials in this regard [12,13,[16][17][18][19][20][21][22][23][24]. The films developed from sugar palm starch are described as non-toxic, colorless, biodegradable, tasteless, odorless, and isotropic.…”

Antibacterial sugar palm starch biopolymer composite films were developed and derived from renewable sources and inorganic silver nanoparticles (AgNPs) as main ingredients for antibacterial coatings. The composite films were produced by solution casting method and the mechanical and physicochemical properties were determined by tensile test, Fourier Transform Infrared (FTIR) analysis, thermal gravimetric analysis (TGA), antibacterial screening test and field emission scanning electron microscopy (FESEM) images. It was found that mechanical and antibacterial properties of biocomposite films were improved after the addition of AgNPs compared with the film without active metals. The weakness of neat biocomposite films was improved by incorporating inorganic AgNPs as a nanofiller in the films’ matrix to avoid bacterial growth. The results showed that the tensile strength ranged between 8 kPa and 408 kPa and the elasticity modulus was between 5.72 kPa and 9.86 kPa. The addition of AgNPs in FTIR analysis decreased the transmittance value, caused small changes in the chemical structure, caused small differences in the intensity peaks, and produced longer wavelengths. These active films increased the degradation weight and decomposition temperature due to the more heat-stable AgNPs. Meanwhile, the average inhibited areas measured were between 7.66 and 7.83 mm (Escherichia coli), 7.5 and 8.0 mm (Salmonella cholerasuis), and 0.1 and 0.5 mm for Staphylococcus aureus. From the microscopic analysis, it was observed that the average size of all microbes for 1 wt% and 4 wt% AgNPs ranged from 0.57 to 2.90 mm. Overall, 3 wt% AgNP nanofiller was found to be the best composition that fulfilled all the mechanical properties and had better antimicrobial properties. Thus, the development of an organic-inorganic hybrid of antibacterial biopolymer composite films is suitable for antibacterial coatings.

Influence of CaCO3 in pultruded glass fiber/unsaturated polyester resin composite on flexural creep behavior using conventional and time-temperature superposition principle methods

et al. 2020

View full text Add to dashboard Cite

The effect of calcium carbonate on the creep phenomenon of glass fiber/unsaturated polyester resin composites (GFRP) (obtained by pultrusion) was investigated due to failure that happened during installation of one of the composite transmission tower. To assess long-term creep and predict the life of composites, a conventional bending method with 45-day creep and time-temperature superposition principle (TTSP) were used. In the conventional method, the composites (with and without calcium carbonate) underwent only slight deformation. It was found that their lifetime could be 25 years. However, based on the standard curve obtained by the TTSP method, significant differences were shown in the stability of calcium carbonate composite samples at 95°C (111 days) and 160°C (11 days). It was found that the addition of calcium carbonate extends the service life of the tested composites. Thus, the results obtained by the conventional method do not reflect the real behavior of the samples over time. On the other hand, the TTSP method allows better estimation of the long-term durability of composites.
