Abstract

The use of natural materials like rattan in eco-friendly composites is gaining attention in materials engineering. However, its hydrophilic nature and interaction with other materials can affect mechanical strength. This study investigates how variations in rattan size and alkali treatment influence the tensile properties of single rattan strips through an epoxy dipping process. Rattan was prepared with varying lengths (5–15 cm), widths (3–8 mm), and a consistent thickness (0.5 mm). Alkali treatment used 5% and 10% NaOH concentrations for 1 and 24 hours. Tensile testing showed that a 5 cm × 8 mm strip achieved the highest tensile strength (49.95 MPa), Young's modulus (3562.77 MPa), and low strain (5.4%), while the 15 cm × 3 mm strip had the lowest strength (9.48 MPa) and modulus (475.69 MPa) with higher strain (10.32%). A 5% NaOH treatment for 24 hours improved adhesion and performance, while 10% caused degradation.

Abstract

The incorporation of wood dust and crumb rubber waste as filler in polymer matrix composite still requires in-depth evaluation of mechanical properties because they have different characteristics. This study evaluates the tensile, flexural, and hardness properties of epoxy composites reinforced with various fractions of wood dust and crumb rubber (5, 10, and 15%). The results showed that the composite with 5% crumb rubber produced the highest tensile strength of 15.52 MPa (CR5), while the highest flexural strength was 30.46 MPa (CR10), and the highest hardness was 75.9 HRC (CR15), indicating superior performance for CR fillers. The observations of the fracture surface showed that increasing the fraction of wood dust contributed to lowering the mechanical performance due to the relatively large distribution of voids and agglomeration. This finding confirms the importance of filler type and fraction selection on composite performance. Future research is recommended to explore filler surface modification and hybrid combinations to improve dispersion and bonding between phases in composites.

Abstract

This study aims to investigate the effect of increasing the concentration of natural filler on the mechanical properties of Spent Coffee Ground (SCG) / Coffee Husk (CH) reinforced epoxy matrix composite. The materials used in this study are epoxy resin as a matrix and waste coffee grounds and coffee husks as natural fillers with sizes of 100-mesh and concentrations of 10, 20, and 30 wt.%. The results showed that SCG 10 wt.% produced the best mechanical properties compared to the other samples based on tensile strength (19.58 MPa), tensile modulus (1.70 GPa), flexural strength (44.55 MPa), and flexural modulus (2.32 GPa). On the other hand, CH 30 wt.% contributed the highest hardness value of 50.33 HRB compared to other samples. The findings in this study prove that the appropriate composition will affect the compatibility between the filler and the matrix, thus impacting the mechanical properties of the composite. This phenomenon can be seen based on microscope analysis, which shows a strong interaction between the matrix and filler and the formation of voids and agglomeration
