Effects of different coupling agents on the mechanical and interfacial properties of oil palm fiber reinforced polypropylene composites

Abstract

This study investigates the effects of fiber loading and coupling agent on the performance of EFB fiber composites of oil palm biomass. The dried EFBs were ground in random sizes for composite production. Fiber composition and fiber morphology were evaluated by SEM and EDAX. Ground fiber was compounded with PP by means of a twin-screw compounder for the preparation of EFB/PP composites. Two types of MAPP were used as a coupling agent during compounding. The incorporated fiber contents for EFB composites were 10—40% (by weight). The test specimens were prepared by injection molding. The composites were characterized by melt flow index and mechanical testing such as TS, TM, FS, FM, and IS. Surface morphology was studied by SEM.

Polypropylene composites reinforced with untreated and chemically treated coir: Effect of the presence of compatibilizer

“…In this process, one hundred grams of fiber were dried, crushed in a knife grinder, and cooked in a 3L batch reactor. Fibers were placed in the reactor together with different concentrations of sodium hydroxide (1,2,4,8, and 12%) and pulped for 2 h. Following pulping, the cooked material was washed until pH 7 for removal of the residual cooking liquor and dried at 70 C 6 3 for 72 h. Pulping conditions were: ambient pressure, temperature 5 100 C 6 4, and pulp consistency 5 30%.…”

“…Moreover, these fibers are abundant and derived from natural renewable sources and in many cases, generated as by-products in the food and furniture industry, such as coir, bagasse, and wood [1][2][3][4][5][6].…”

Characterization of untreated and treated male and female date palm leaves

“…There are many types of treatments used to improve the fiber surface to modify the strength of the fiber-matrix interface which provides an effective improvement on mechanical and physical properties of composites [11][12][13]. It is significant to recognize the change in the fiber structure after the treatment which is influenced by the morphology, type, and processing conditions [14][15][16].…”
