“…The thermal stability and ability of PAACTPF to withstand the processing temperature when used as reinforcement in polymer composites can be understood from its TGA‐DTG curve. The samples of ACTPF and PAACTPF were heated from ambient to 120°C and the dehydration of samples was observed 48 . This is noted as minimum weight loss of 7.2% and 6.5% for ACTPF and PAACTPF respectively.…”

This paper investigates thermo-mechanical, chemical, and morphological characteristics of alkali pretreated and enzyme treated Areca catechu tree peduncle fibers (ACTPFs) for probable reinforcement in polymer composites. ACTPFs were pre-treated with 0.4 M NaOH solution and treated with enzymes such as xylanase, laccase, and pectinase before investigations. Alkali pre-treated ACTPF (AACTPF) cum pectinase treated AACTPF (PAACTPF) exhibited maximum cellulose content 57.28 wt% and single fiber tensile strength 203.5 ± 22.12 MPa. Further, the crystallinity index and crystal size of PAACTPF was determined as 55% and 12.9 nm by x-ray diffraction analysis. Also, the prevalence of chemical bonds and thermal stability up to 233 C in PAACTPF was exposed through Fourier transform infrared spectroscopy analysis and thermogravimetric analysis respectively. Moreover, the coarse surface of PAACTPF viewed through scanning electron microscope owing to removal of amorphous contents makes it a considerable counterpart for substitutional reinforcement to artificial fibers in polymer composites.

The comparatively lesser weight loss observed for PAACTPF is owing to the removal of moisture content during pectinase treatment.…”

Circular Production, Designing, and Mechanical Testing of Polypropylene-Based Reinforced Composite Materials: Statistical Analysis for Potential Automotive and Nuclear Applications

The circularity of polymer waste is an emerging field of research in Europe. In the present research, the thermal, surface, mechanical, and tribological properties of polypropylene (PP)-based composite produced by injection molding were studied. The pure PP matrix was reinforced with 10, 30, and 40% wt. of pure cotton, synthetic polyester, and polyethylene terephthalate post-consumer fibers using a combination of direct extrusion and injection molding techniques. Results indicate that PP-PCPESF-10% wt. exhibits the highest value of tensile strength (29 MPa). However, the values of tensile and flexural strain were lowered with an increase in fiber content due to the presence of micro-defects. Similarly, the values of modulus of elasticity, flexural modulus, flexural strength, and impact energy were enhanced due to an increase in the amount of fiber. The PP-PCCF-40% wt. shows the highest values of flexural constant (2780 MPa) and strength (57 MPa). Additionally, the increase in fiber loadings is directly proportional to the creation of micro-defects, surface roughness, abrasive wear, coefficient of friction, and erosive wear. The lowest average absolute arithmetic surface roughness value (Ra) of PP and PP-PCCF, 10% wt., were 0.19 µm and 0.28 µm. The lowest abrasive wear value of 3.09 × 10−6 mm3/Nm was found for pure PP. The erosive wear value (35 mm3/kg) of PP-PCCF 40% wt. composite material was 2 to 17 times higher than all other composite materials. Finally, the single-step analysis of variance predicts reasonable results in terms of the p-values of each composite material for commercial applications.

This investigation aims to study the influence of various environments, such as groundwater, seawater, mineral water and sub‐zero, on reinforced polyester/S‐glass/sisal composites with nano clay (NC). Composites with a configuration of S‐glass/sisal/sisal/S‐glass (GSSG) with different wt% of NC, such as 0, 2, 4, and 6, were manufactured using the hand lay‐up method. For 6 days, the composites were conditioned in different environments like seawater, mineral water, groundwater at room temperature, and sub‐zero environments at −17°C. The influence of these environments on the tensile and flexural properties of manufactured composites was studied. Composites with 4% NC displayed higher tensile strength, while composites with 2% NC exhibited maximum flexural strength for all the environments. It was perceived that the weight gain was maximum in seawater (0.1857 g) and minimum in mineral water (0.06 g) and sub‐zero (0.101 g) conditions for 6% NC condition. Tensile and flexural strengths were reduced by 27% and 24% when samples were submerged in seawater compared to other environments. TEM images for 4 wt% of NC and 6 wt% of NC were studied for dispersions of NC in Polyester, and the effect of NC mixing with polyester was understood for the hybrid polymer composites.Highlights A novel hybrid composites were fabricated using a double stirring process. The ultra‐sonication led to uniform distribution of nanoparticles. The mechanical properties and the effect of environments on these properties are studied. SEM images revealed the aging due to various environments. The hybrid composites can store mineral water and the sub‐zero environment.
