Properties of organic and inorganic filler hybridization on TimohoFiber‐reinforcedpolyester polymer composites

Abstract

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.

Polymer composites from natural fibers and recycled waste surgical masks during COVID‐19 pandemic

“…As expected, the fibers are undergoing two‐step degradation, while the masks are showing single step degradation. This is due to degradation of fibers are initiated at a lower temperature than polymer 46,47 . The maximum degradation of both sisal and hemp fibers are observed at 320–350°C, whereas pure polypropylene shows maximum degradation at 450°C.…”

“…This is due to degradation of fibers are initiated at a lower temperature than polymer. 46 , 47 The maximum degradation of both sisal and hemp fibers are observed at 320–350°C, whereas pure polypropylene shows maximum degradation at 450°C. On the other hand, the final degradation temperatures are increased from 459.77 to 470.47 and 473.79 for pure PP masks, sisal and hemp respectively.…”

Influence of calcium carbonate fillers on pine fiber reinforced polyester composites

“…This increment was due to the ability of filler particles to support the stress transfer between matrix and fiber, also the strong interfacial bonding due to the chemical treatment of PFs. [ 73,74 ] The remaining 10 vol% filler‐loaded composites PF1/CCP10, PF2/CCP10, and PF4/CCP10 exhibited flexural strengths of 97.89, 146.51, and 149.49 MPa, respectively. The 5 vol% filler‐loaded composites also exhibited good flexural strengths, and the values were slightly lower than 10 vol% filler‐loaded composites.…”

Evaluation of mechanical, thermal and morphological properties of corn husk modified pumice powder reinforced polyester composites

“…Corn husks were immersed in fresh water for 10 days (Figure 1B) to allow micro-bacterial deterioration, which was supposed to aid in the process of separating the fibers from the corn husk flesh. [50][51][52] They are then combed to take up the fibers on the skin before being sun-dried. In addition, the corn husk fibers (CHF) were trimmed to a length of 10 mm and were ready for usage (Figure 1C).…”
