“…These processes, can either be mechanical (damage from impacts, delamination, extreme heat, creep, and water absorption) or chemical degradation. Metals, ceramics and polymers are used as matrices in composite materials development; however, polymers matrices have a wide range of applications due to their lightweight and easy processability compared to metals and ceramics [3][4][5][6][7][8][9].…”

Combining two or more polymers as a blend is necessary rather than synthesizing new ones for the balance of polymer properties for end-use applications. This work introduces a sustainable polymer blend (matrix) for high-impact applications, as the accessibility and cost of production of these high-impact polymers keep souring. This was achieved by designing an experiment using design expert v10.0 to account for the number of experimental runs and optimise the polymer blend. Mechanical, dynamic mechanical, and temperature effects were considered on the blended polymer. Sixteen ( 16) experimental runs were generated with blend ratio as the independent variable and Impact Strength (IS) and Tensile Strength (TS) as the responses. The optimal blend ratio was obtained for wPP, PP and NR as 23, 30 and 47 % respectively. While, the optimum conditions for maximum impact and tensile strengths from the D.E was 241.62 J/m and 118.04 MPa respectively, with a desirability of 0.973. While the validated values obtained were 248.9 J/m; with errors of 2.93 % and 120.14 MPa; with an error of 1.75 % respectively. Thermogravimetry analysis revealed a single peak degradation for sp17, sp18, and sp19 (control samples) while multiple degradation peaks were observed for the blends. It was believed to be a result of different times for degradation of the individual components forming the polymer blend. Also, the T d onset started around 300 o C and the T d offset was around 500 o C for all tested samples. While, the Dynamic Mechanical Analysis (DMA) showed that there was an improvement in the T g and damping factor for sp5 (109 o C, 0.171) as compared to sp17 and sp18 (81.1 o C, 0.089 and 104.3 o C, 0.061), but no improvement was recorded for storage and loss moduli. SEM micrographs showed a good surface morphology for the blend with optimal mechanical and thermal properties. The blend can be utilized for engineering applications, including matrices for body armour, helmets, car bumper, etc.

“…Most composite materials are made up of a continuous matrix phase and a non-continuous reinforcement phase that is harder and stronger than the matrix phase [18]. Traditional bres and/or composites such as glass, carbon, or aramid ber-reinforced thermoplastic and thermosetting resins, on the other hand, are not environmentally friendly [19]. As a result, one of the solutions proposed by researchers is natural bre reinforced composites [20].…”

Bamboo is an ancient structural material used for a variety of applications in India. Bamboo is widely used in the global south for frames, bridges, housing, and transitory structures. Bamboo supply has been effectively inexpensive as well as plentiful in global south countries to meet the widespread need for affordable housing. The current research focuses on the mechanical properties of bamboo fibre reinforced polymer composite materials for use in structural industries. Moreover, a bamboo fibre reinforced composite was compared to glass fibre in a variety of ways, and it was discovered that the bamboo fibre composite outperformed the glass fibre in a few areas. Investigations revealed the potential use of bamboo fibre reinforced composite with good stiffness but a lower strength limitation than glass fibre composite. Tensile strength of 40.53 MPa and hardness value of 68.2 RHN were achieved by E-glass epoxy composites. However, the results of bamboo fibre reinforced composites cannot be overlooked. Further research was conducted to improve the mechanical properties, and the results were satisfactory.

“…However, when multiple mixtures of polymers (matrices) are used, it is termed a polymer blend [5,9,10]. Among the composites, polymer matrix composites are becoming prominent in their applications, and they are the most used matrices in manufacturing companies due to their light weight and ease of fabrication [11][12][13][14][15][16].…”

In this work, the effect of jute nanofibre on ter-blend of waste polypropylene (wPP), polystyrene (PS), and natural rubber (NR) nanocomposite was studied. The nanofibre was produced from jute fibre via a ball milling process after freezing with liquid nitrogen. The produced nanofibre was analyzed using Fourier Transform Infrared Spectroscopy (FTIR) and Dynamic Light Scattering (DLS). The ter-blend was modified with the nanofibre at different weight percentages (2–10 wt%) at 2wt% intervals. The modified polymer blends were characterized for mechanical, thermal, physical and morphological properties. FTIR revealed the removal of hemicellulose, lignin and other impurities from the jute fibre, due to the change in wave numbers observed. The DLS analysis showed that an average of 85.54 nm size distribution by the intensity and Polydispersity Index (PDI) of 0.353 was achieved. Also, the thermogravimetry analysis (TGA) showed that jute nanofibres proved to be thermally stable up to 282 oC. Polymer blends modified with 2 wt% nanofibres had the highest average impact and tensile strengths. While, the percentage water absorption (%WA), showed that sp10% absorbed the highest amount of water after 24 hrs. The weight losses of the modified blend at various temperatures were found to increase with the addition of nanofibre. The Scanning electron microscope (SEM) revealed cracks, voids and blend-separation as the amount of jute nanofibre was increased. While, Dynamic Mechanical Analysis (DMA) revealed that the Tg of the modified blend was improved, while the loss-factor improved greatly by 43%, but the storage and loss-moduli remained unchanged.
