Transverse Power Resin Acrylic Heat Polymerization After the Addition of Banana Fronds Fibers (Musa Acuminata L)

Introduction

Heat polymerization acrylic resin is a versatile material widely used in various engineering and medical applications due to its numerous advantages. However, one of the primary weaknesses of this resin is its fragility, which can lead to breakage under high mechanical pressure. Recent research has shown that the addition of fibers can significantly improve the mechanical properties of acrylic resins, particularly in terms of transverse power. Among the various natural fibers, banana fronds have gained attention due to their superior mechanical properties compared to other natural fibers. This study aims to evaluate the effect of adding banana fronds fibers to heat polymerization acrylic resin on its transverse strength.

Materials and Methods

The sample used in this study consisted of heat polymerization acrylic resins in the form of plates with dimensions of 65 mm x 10 mm x 2.5 mm. The study was divided into four groups: the control group (I) without the addition of fiber and groups with the addition of fiber as much as 5% (II), 10% (III), and 15% (IV) based on weight. Each group consisted of ten samples. The mixing process was carried out until homogeneous, and then the material was put into a mold to be pressed. The curing process was carried out in a waterbath, starting from room temperature to reach 100 °C for 20 minutes.

Transverse Strength Testing

Transverse strength testing was done using a Universal Testing Machine with a load of 50 kgf and a crosshead speed of 5 mm/minute. The data analysis was carried out by Kruskal-Wallis and Mann-Whitney tests to determine the significance of differences between groups. The analysis showed that the average and standard deviation of the transverse strength value of groups I to IV were 102,253 ± 12,921 MPa, 58,648 ± 8,375 MPa, 51,519 ± 11.884 MPa, and 42.508 ± 3,637 MPa, respectively. The Kruskal-Wallis test showed a significant difference in transverse strength (p < 0.05) with a value of p = 0.000. The results of the Mann-Whitney test stated that there were significant differences (p < 0.05) between groups I and groups II, III, and IV, as well as between group II and IV.

Results and Discussion

The results of this study showed that the addition of banana fronds fibers to heat polymerization acrylic resin affects the transverse power. There was a significant decrease in the value of the transverse strength from the control group (I) to groups with fiber (II, III, IV), indicating that although banana fronds have the potential to improve the quality of the material, the right proportion needs to be considered to avoid a decrease in mechanical strength. Further research is needed to deepen and understand the interaction between natural fiber and resin in improving the mechanical performance of this material.

Conclusion

The use of banana fronds fibers in heat polymerization acrylic resin has been shown to affect the transverse power of the material. The results of this study suggest that the addition of banana fronds fibers can lead to a decrease in the transverse strength of the material, highlighting the need for further research to optimize the proportion of fiber addition. The findings of this study provide valuable insights into the potential of natural fibers as reinforcement materials for acrylic resins and encourage further exploration of their industrial applications.
