“…Consequently, an improved and significantly increased tensile strength of the composite was observed. It is already reported earlier by Sumesh et al [60] that small fine particles like ash/degraded materials increase the physical interaction between reinforcing fiber and BM. So, the combined effect of both physical and chemical interactions among SSL and BM must have been the reason for this substantial improvement in the tensile properties.…”

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.

The viability of using cellulosic Cymbopogon flexuosus root (CFR) fiber waste from the industry as a reinforcing material in a polyester-reinforced composite was investigated. Initially, CFR anatomy, mechanical, thermal, physio-chemical, morphological, and spectroscopy behaviors were investigated. Spectroscopy and chemical analysis were evidence for the richness of cellulose content (74.33%) in the fiber which reflected in increased tensile strength of 315.22 ± 61.72 MPa and thermal stability 272.31 C. Fiber reinforcement was varied from 0 to 50 wt% at random orientation and mechanical, and water absorption properties were correlated with the glass fiber reinforced composite of the same weight percentage. The composite with a 40% fiber combination has an enhancement in mechanical, morphological, and thermal characterization. This comprehensive study confirms the usage of this bio-material in replacing harmful synthetic material in structural, marine and mechanical industrial applications.

“…The hybrid fiber incorporation of pineapple/sisal at 30 wt.% along with fly ash at 1–5 wt.% enhanced the wear resistance of epoxy-based composites, proving the influence of natural reinforcement and fillers in enhancing the properties [13]. Cellulosic nature in flax fiber showed good frictional properties in polymer based composites.…”

In this experimentation hybrid composites using natural fibers and titanium oxide (TiO2) nano filler were fabricated using compression moulding technique. Pineapple (P) and Sisal (S) fibers were used as the natural reinforcements with epoxy as the matrix material. The mechanical results of flexural, impact and tensile properties found good improvement in the properties with SP fiber reinforcement (1:1 ratio) and TiO2 filler addition. The combination with 40 wt.% SP/5 wt.% TiO2 observed better mechanical results. The Taguchi optimization results showed lower Specific Wear Rate (SWR) by the incorporation of high TiO2 filler (5 wt.%) addition with the polymer-based composites. The filler substitutes replace the vacant space between fiber/matrix phase and add to the properties. The multi response optimization with TOPSIS proved that hybrid SP has the high influence in overall tribological properties of the natural fiber composites with rank 1 followed by filler incorporation. The results showed combination with 5 wt.% TiO2/20 wt.% SP Hybrid fiber/500 m Sliding distance/Sliding speed of 1 m/s and applied load of 5 N having optimized results.
