“…Increasing the NBR ratio and decreasing the EPDM ratio in rubber composites (Table 1) affects the cross-link density and the elongation at break value. According to Kim et al [56], the difference in the EPDM ratio of rubber composites can affect breakout extension values. In formulas B and C, NBR and EPDM produce an elongation at break value that is equal to the value of the elongation at break formula A (Fig.…”

This research aims to study the mechanical properties of natural rubber composites with nitrile butadiene rubber and ethylene propylene diene monomer rubber. Composite fillers consisted of kaolin, and softener using used cooking oil. The study was carried out by the method of mastication, vulcanization, and maturation of the compound into rubber vulcanizates. The vulcanization and mastication process is carried out in the open mill. The maturation of the compound into rubber vulcanizates from the results of mastication and vulcanization was carried out using semi-automatic heat press and press at a temperature of 130 °C ± 2 °C for 17 min. Based on data from testing the mechanical properties of five samples from five formulas, the mechanical properties of composite rubber are affected by the ratio of natural rubber, synthetic rubber, kaolin, and used cooking oil as a softener. The difference in the results of vulcanizates rubber testing of natural rubber composites with synthetic rubber is not only influenced by the ratio of the composite, but also by the degree of cross-linking between the material molecules.

“…A grommet is typically made from hyper-elastic materials, such as the ethylene propylene diene monomer (EPDM), and is used to secure the position of cables embedded in a vehicle [1][2][3][4][5][6][7]. Because EPDM materials boast excellent elasticity-recovery properties and a high friction coefficient, they are utilized in research on bonded and dustproof parts [8][9][10].…”

Numerical Estimation of Bonding Force of EPDM Grommet Parts with Hollow Shaft Geometry

A grommet is a representative component that fixes the position of a cable. It is made from hyper-elastic materials (rubber), such as ethylene propylene diene monomer (EPDM). The grommet and cable are conventionally fixed through bonding; however, this method has numerous disadvantages that can be improved through relevant research. To apply a fixing method using the elastic force of EPDM rubber, this paper presents an empirical equation for approximating the bonding force of EPDM grommet parts with a hollow shaft geometry. First, tensile tests and the inverse method were used to approximate the basic mechanical properties. The physical properties were derived through basic tests; furthermore, bonding force tests and the inverse method were used on a grommet with a hollow shaft structure. In addition, the Box–Behnken design of experiments was used to predict the amount of change in the bonding force according to the geometry variables. Finally, this study was validated by comparing the approximation results derived through the design of experiments with the analysis and bonding force test results.

“…This material could not be used to produce charcoal briquettes unless mixed with other charcoal types. An experimental mixture design required two or more ingredients to produce new compound in order to indicate the influence of each ingredient (components, q) on the variables and to obtain the optimal mixing ratio [51]. This was based on the mixing principle using the summed quantity(x i ) of the mixing components (q) = 1, as shown in Equations ( 1) and (2).…”

This study aims to increase the quality and value of raw materials with a low higher heating value, HHV (secondary ingredients), but which is abundantly available throughout the year by mixing it with high HHV materials (main ingredients) to obtain quality and standardized charcoal products in accordance with the industrial product standards as approved for commercial use. As for the ingredients, charcoal A is Eucalyptus bark coal (EuBC) with an average HHV of 3779.98 cal/g, charcoal B is rice husk coal (RHC) with an average HHV of 4863.29 cal/g, and charcoal C is charcoal from a biomass power plant (CBPP) with an average HHV of 5991.18 cal/g. The results from the simplex-centroid mixture design method allowed increased quality and value of the biomass charcoal powder (raw material) that has a low heating value but is sufficiently available throughout the year due to the mixing of secondary ingredients with raw materials that have a high heating value (main ingredient). The charcoal briquettes production must be qualified and meet the industrial product standards, and be approved for commercial use.
