Comparative experimental studies of phosphate glass fiber/polypropylene and phosphate glass fiber/natural rubber composites

Abstract

Phosphate glass fiber (PGF)-reinforced polypropylene (PP)/natural rubber (NR)-based unidirectional composites with four levels of fiber loading (5, 10, 15, and 20 wt%) were fabricated by compression molding. The influence of the addition of fiber loadings on the mechanical properties such as tensile strength, bending strength, tensile modulus, and percentage elongation at break of the composites was investigated. Based on the fiber loading, 20% PGF-reinforced PP composites yielded better mechanical properties compared with the PGF/NR composites. Degradation tests of the composites were performed in aqueous and soil medium, and it was found that PGF/NR composites lost much of its original strength and modulus compared with that of the PGF/PP composites. Interfacial shear strength (IFSS) of PGF/PP and PGF/NR systems was investigated using the single-fiber fragmentation tests. The IFSS of PGF/PP and PGF/NR systems appeared to be 5.5 and 1.1 MPa, respectively.

Numerical and experimental investigation of fiber metal laminates with elastomeric layers under low‐velocity impact

“…The Mooney viscosity of the compounded elastomer was 65 (purchased from the Rubber Research Institute of Malaysia). Natural rubber was utilized in light of its superior properties such as biodegradability, flexibility, tear resistance, and damping capacity 27,28 . Moreover, stearic acid, ZnO, accelerators, stearic acid, and sulfur (LG Company) were used in the vulcanization bonding process.…”

The elastomer density was found to be 1255 kg/m 3 The composite layer included plain-woven glass fibers (200 g/m 2 ) and ML-506 epoxy resin obtained from Metyx Co. (Turkey) and Mokarrar Company (Iran), respectively.…”

Impact characteristics of soft composites using shear thickening fluid and natural rubber–A review of current status

“…The latter involves organic compound isoprene and small impurity contents of other organic materials along with water [195]. Due to its excessively large softness, it is modified in properties by the addition of filters, e.g., SiO2, S, and carbon black [198]. It has satisfactory friction, fatigue, and abrasion resistance.…”
