A Study of Some Mechanical and Physical Properties for Palm Fiber/Polyester Composite

Abstract

This research has been done by reinforcing the matrix (unsaturated polyester) resin with natural material (date palm fiber (DPF)). The fibers were exposure to alkali treatment before reinforcement. The samples have been prepared by using hand lay-up technique with fiber volume fraction of (10%, 20% and 30%). After preparation of the mechanical and physical properties have been studied such as, compression, flexural, impact strength, thermal conductivity, Dielectric constant and dielectric strength. The polyester composite reinforced with date palm fiber at volume fraction (10% and 20%) has good mechanical properties rather than pure unsaturated polyester material, while the composite reinforced with 30% Vf present poor mechanical properties. Thermal conductivity results indicated insulator composite behavior. The effect of present fiber polar group induces of decreasing in dielectric strength, and increasing dielectric constant. The reinforcement composite 20% Vf showed the best results in mechanical, thermal and electrical properties.

Performance Evaluation of Chestnut Nano Particles on Tensile, Impact, Vickers Hardness of Polyester/Glass Fiber Composite

“…While the samples (D and E) with 6% and 9% nano chestnut particles, respectively, showed a reduction in the impact strength value with the increase of weight fraction of nano chestnut shell powder (NCSP), which led to a decrease of matrix elasticity and also decrease of the adhesion with E-glass/UPE composite. (NCSP) concentration inside these composite decreases the capability to absorb energy and reduces the value of toughness; therefore, the fraction impact strength decreases [18].…”

“…Natural fillers, e.g. chestnut, are used by researchers to produce polymer composite with enhanced characteristics [17][18][19][20][21][22]. Chestnut fillers are obtained directly from natural resource; it is cheap and has advantages due to their renewable nature, available in abundance [23].…”

The Effect of Multi-Walled Carbon Nanotubes on the Mechanical Properties of Composite Material Carbon Fibers/Polyester Used in Ships Hulls

“…The results of the study, which looked at the mechanical properties of a composite material made of carbon fibers and polyester in a varied ratio with the inclusion of carbon nanotubes, showed an improvement in the mechanical properties of the composite material [31]. The study examined the mechanical, thermal, and electrical characteristics of a composite material reinforced with natural fibers (palm fibers), polyester, and fibers at various volume fractions, and came to the conclusion that the volume fraction at 30% had poor mechanical characteristics [32].The researchers showed how carbon nanotube behaviors may be studied experimentally to identify mechanical characteristics such as Young's modulus, shear modulus, bending behavior, and vibrational response [33][34][35][36][37][38]. The experiment results showed an improvement in tensile stress in various proportions, and the study examined the impact of silicon nano dioxide on the mechanical properties and crack growth in the microstructure of the composite material of carbon/polyester fibers at different weight fractions used in the manufacture of boat hulls [39].…”

A Review of some Characteristics of a Composite Hybrid Socket for Prosthetics Derived from Plant Fibers

“…Several benefits, such as reduced tool wear, make composites an attractive alternative to synthetic fibers. Their characteristics are modified by the orientation of the fibers, making them useful in composite materials [16,21,22]. Composites containing natural fibers are becoming increasingly popular during the past few decades.…”

“…fiber-reinforced composites. Numerous forms of plant matter, including bast, leaves, fruits, wood, cereal straw, and grass, can be processed into yarn or thread [22]. Plant-based fibers are composite materials found in nature.…”
