“…[1][2][3][4][5] Innovation and development have been conducted to improve the performance of natural fiber composites. [6][7][8][9] Natural fiber has been proven to be able to increase physical, mechanical, and thermal characteristics of the polymer when put in exact proportion. [10][11][12] So as the Timoho Fiber (TF) composite, TF composite is proven to have characteristics which can be used as composite green reinforcement.…”

Eco-friendly composite made of Timoho Fiber (TF) continuously developed to get the best performance to replace plastic-based synthetic fibers. This study focuses on investigating physical characteristics, mechanical properties, thermal analysis, and the morphology of TF-reinforced polyester composites by adding organic (egg shell powder-ESP) and inorganic (aluminum powder-AP) fillers. Hot press method was used in the composite fabrication with considered volume fraction of TF, organic, and inorganic fillers. The results showed that the density of TF-polyester composites decreases with the increasing volume fraction of the fibers. For additional fillers, it was shown that AP was more effective to be used to improve density than ESP. The tensile and impact strength of the composite increased with increasing TF volume. However, the addition of ESP and AP fillers into the composite caused different mechanical characteristics. Filler addition increased the elasticity modulus, toughness, thermal resistance increased, while the tensile strength decreased. ESP and AP fillers provided the best thermal resistance due to the relatively high thermal conductivity of ±1700 C compared to composites without fillers and amorphous ESP fillers. SEM observation supported the analysis of TF-polyester composite mechanical characteristics.

“…In another study, use of 2 wt.% of FA with short sida acuta fiber reinforced polymer composite reported enhanced mechanical properties compared to pristine polymer and other composites. [47] Likewise, evaluation from our previous work showed that using FA size lesser than 2 μm, treating FA with amino silane (APTES)/ cetyltrymethyl ammonium bromide (CTAB), and using the treated FA of 5 wt.% along with 25 wt.% of SSL in base matrix (BM) gives much superior properties. [4,44,48] Resistance against agglomeration and compatibility of the FA with BM was exhibited due to the selective APTES/ CTAB treatment of FA.…”

The investigation explores mechanical, thermal and thermomechanical behavior of hybrid composites post-recycling, and subsequent, 5 wt.% additional reinforcement to the recyclate of sisal (SSL) fiber fly ash (FA)/polypropylene (PP) hybrid composite. Impact of recycling and 5 wt.% of SSL fiber reinforcement of the recyclate on mechanical properties of hybrid composites made of 15-30 wt.% SSL and 5-15 wt.% FA were investigated. Noticeably, after recycling, a minimal loss of 2.39% only in tensile and 2.20% in flexural strength were recorded for the hybrid composites fabricated with 15 wt.% each of FA and SSL. The highest loss in tensile (10.32%) and flexural (4.22%) strength were reported for only 30 wt.% SSL fiber reinforced PP indicating that hybridization with FA has a benign effect on reducing property degradation. These lost properties were regained by reinforcing recycled composites with 5 wt.% of SSL fiber. Mechanical studies showed that the composite with 30 wt.% SSL fibers recycled and reinforced with additional 5 wt.% fibers showed a substantial improvement of ~10% and ~4% in the tensile and flexural strength while keeping the impact strength stable. FE-SEM images confirmed a reduction (~67%) in aspect ratio of the SSL fiber due to reprocessing. DMA demonstrated a decrease of ~11% in storage modulus of the composites after first recycling. TGA confirmed an insignificant change in the degradation temperature of the recycled and re-reinforced recycled composites versus fresh composites. The study paves the way for potential future recycling applications of waste natural fiber reinforced PP.

“…During the degradation, α‐cellulose is converted into anhydrocellulose and levoglucosan. [ 13 ] A moderate mass degradation (about 15 wt%) was initiated around 400 and ended at 550°C correlated to the lignin decomposition. In the DTG curve, a peak appeared at 239°C connected with eradicating hemicellulose components from the VMF.…”

This article is designed to examine the aptness of Ventilago maderaspatana fiber (VMF) as reinforcement in polymer composites. A significant quantity of cellulose fraction (56.12 ± 5.42 wt%) in the VMF was estimated via chemical analysis. The X-ray diffraction analysis identified the presence of cellulose type-I and peak cellulose type-IV in the VMF, and it quantified the crystallinity index (25.88%) and crystalline size (26.12 nm) of the VMF. Various chemical functional groups in the VMF were categorized with the help of Fouriertransform infrared spectroscopic analysis. The thermal degradation behavior of the VMF was investigated with the help of thermogravimetric analysis, and it determined the thermal stability (200 C) and kinetic activation energy (62.46 kJ/mol) of VMF. The scanning electron microscopic and energy dispersive X-ray spectroscopic analysis revealed the existence of contaminations, hemicellulose and lignin on the outer layer of VMF, and it was confirmed by atomic force microscopic analysis. The lower density (1236 ± 18.42 kg/m 3 ) and better tensile strength (383.7 ± 16.07 MPa) of the VMF enabled the possibility of use as reinforcement in fiber reinforced plastics.
