“…One should note that SiO 2 is an excellent filler and commonly used in the fabrication of inorganic composites. Previously, RHNS has been applied to polymer reinforcements, such as high-density polyethylene (HDPE) [25], polyvinyl chloride (PVC) [26] and epoxy resin [27], to reduce the friction coefficient and improve wear resistance [28]. However, the modification of PHBV by RHNS has not been reported yet.…”

Poly(3-hydroxybutyrate–co–3-hydroxyvalerate) (PHBV) is a biodegradable polymer and has several potential applications. Herein, we have used a rich biomass resource, rice husk, to obtain rice husk nano-SiO2 (RHNS) and prepared RHNS/PHBV composites by using hot-press molding. The results showed that the amorphous nature of spherical nano-SiO2 particles with an average diameter of 40–80 nm was obtained. The tensile strength and flexural strength of the RHNS/PHBV-3 composite reached up to 23.515 and 75.669 MPa, respectively, corresponding to an increase of 33.65% and 15.54% as compared to pure PHBV. The enhanced mechanical properties of the RHNS/PHBV composite can be attributed to the uniform dispersion and strong interfacial bonding of RHNS with the PHBV matrix. In addition, the water absorption rate of the RHNS/PHBV composite increased from 0.26% to 0.35% and the water swelling ratio followed the given order in different directions: thickness > width > length. Furthermore, the initial degradation temperature and residual rate of combustion at 700 °C of the composites increased with higher content of RHNS, which represents the enhanced thermal stability of RHNS/PHBV composites. In summary, RHNS served as an excellent reinforcement and RHNS/PHBV composites have shown promising properties for various potential applications.

In the current scenario, the applications of natural fibers are increasing enormously due to their biodegradability, low-density and better mechanical properties. This research explains the machining nature of pineapple (P) and flax (F) fibers by the incorporation of cellulose micro filler (CMF). These epoxy-based composites were manufactured using compression moulding. In the machining process using abrasive water jet machining (AWJM), lower kerf angle of 1.31° and surface roughness of 5.1 µm were observed in 30% PF/2% cellulose micro filler hybrid epoxy combination. Agglomeration at higher filler incorporation causes decrease in machinability of hybrid 30% PF. Pineapple and flax hybrid fibers with 30 and 35 wt % showed better machinability at 2 and 3% cellulose micro filler addition. Scanning electron microscopy analysis after machining process showed reduction in flush off and pullouts of fiber by improved compaction with the epoxy matrix due to filler addition.

Almost fully dense high-density polyethylene (HDPE) reinforced with submicron-sized titanium dioxide (TiO 2 ) ceramic filler (up to 40 vol %) was fabricated using compression molding. More than 98.5% ρ th (theoretical density) could be obtained for all the HDPE compositions and its measured density varied between 0.94 and 2.25 g cc −1 . The hardness of HDPE increased considerably from 32.6 to 69 MPa (i.e., by two times) with the addition of 40 vol % TiO 2 . The compression strength (19.03-34.16 MPa) and modulus of elasticity (0.49-1.05 GPa) of HDPE were also found to increase with the addition of TiO 2 filler. However, the HDPE exhibited good ductility (59% strain) up to 20 vol % TiO 2 and it was reduced with the further addition of TiO 2 . The strain decreased drastically to 7.6% for HDPE-40 vol % TiO 2 . Addition of TiO 2 filler leads to a considerable decrease in wear rate and coefficient of friction (COF). The wear studies revealed that the HDPE-40% TiO 2 composite exhibited a low wear rate of 1.82 × 10 −5 mm 3 N m −1 and COF of 0.13. The dielectric constant of HDPE (at 10 kHz) was also considerably increased from 5.31 to 20.02 with the addition of TiO 2 up to 40 vol %. Achievement of such high dielectric constant for HDPE materials is the highest ever reported for HDPE.
