Mechanical Properties of Heat Cured Acrylic Resin Reinforced with Natural Sisal Fibers Powder

Abstract

Materials and Methods: In total, 90 specimens were prepared to be used in the study. The specimens were divided into (3) main groups depended on the presence of sisal fibers powder, first group (30) specimens of heat cure PMMA without additives (control), second and third experimental groups of 60 specimens of heat cure PMMA with salinized sisal fibers powder with two different weight percentages (1 and 3%) wt. Three point bending test was used to measure the flexural strength of the specimens, while the impact strength was done by impact testing Charpy’s machine and tensile test was performed according to ASTM (D-638). Data analysis was performed using (ANOVA) test. The results of this study refer to a highly significant in the flexural strength and tensile strength of specimens reinforced with sisal fibers powder compared with control specimens. Non-significant difference was detected in impact strength among the reinforced groups and control gro. Reinforcement of acrylic resin with natural sisal fibers powder affects its flexural strength and tensile strength with non-significant in impact strength.

Synthesis of PVA Nanofibers to Enhance the Mechanical and Thermal Properties of PMMA Matrix for Denture Base Applications

“…The impact exam used to study the toughness of the prepared materials, where the toughness is a factor of the material ability to absorb energy during the plastic deformations, whereas the ductile materials have high toughness due to the high amount of plastic deformation that can be tolerated. (7,8) As indicated in figure 3 (a), the impact specimens were prepared with dimensions according to the standard ASTM (80 mm x 10mm x 4mm) for un-notched specimens, while figure 3(b) shows the experimental impact samples that prepared in this work. The impact strength results of prepared composite materials summarized in figure 4.…”

Study of The Dispersion Effect on the Mechanical Properties of Polypropylene Composites Reinforced With Polystyrene Nanofibers

“…After fiber reinforcing, tensile strength considerably improves. There is no statistically significant difference in flexural strength between the reinforced groups and the control group [13]. Impact strength is very important property ,it expressed in terms of the amount of energy absorbed before fracture, and it can calculated by [14]:…”

Preparation and characterization of nanocomposite textile filter for separation of the oil/water mixture using PA-PVA blends reinforced with carbon nanoparticles

“…Since there have been several oil spill tragedies as well as rapid industrialization during oil production or transportation, which has resulted in significant loss and long-term damaging consequences on the environment, oil/water separation has become a research hotspot recently. Many methods have been used to separate the emulsion of oil -water; as settling, heating, distillation, centrifuging, electrical treatment, chemical treatment and filtration 4 , however, their efficiency in extracting oil from emulsified oil/water combinations is limited. Filtration is thought to be one of the most effective techniques for separating emulsions Reverse osmosis, nanofiltration, ultrafiltration, and microfiltration are the four types of filtration.…”
