“…The strength of the composites started to deteriorate with further increase fiber percentage at 60% of PEFB. This is supported by previous studies that at volume fraction greater than 50%, the fibers tend to aggregate in the composite which weakens the interfacial area and debonding tends to take place between the fibers and matrix [10].…”

The study presents preparation and performance test of Palm Empty Fruit Bunches (PEFB) reinforced box waste coated superhydrophobic coating for shoe sole application. The main purpose of this analysis is to determine the optimal composition of PEFB reinforced with box waste for use in shoe soles. In this study, the use of PEFB and box waste is to replace the synthetic materials in the application of the shoe sole. Additionally, environmental problems can be reduced by using waste PEFB as a value-added product rather than biomass waste. Sample preparation involved grinding of PEFB fibers and box waste, blending processes of different PEFB percentages at 20%, 40%, 60% and 80% mixed with 50% box waste. Followed by the process of mixing with epoxy and hardener, and finally coated with superhydrophobic coating using a spray gun method. Epoxy resin and hardener are used as binders for the bonding between the PEFB fiber matrix and the box waste to be applied to the shoe sole. The study was carried out in both mechanical and physical studies. The test for tensile strength showed 40% PEFB reinforced with 50% box waste with 181.36N maximum load and 16.70% of strain. The 40% PEFB composition showed the optimum bursting pressure to 13.62kgf and the abrasion resistance had a lower weight loss of 0.28 g. The 80% higher proportion of PEFB indicates a lower density of 1.06g/cm3 and a higher porosity of up to 0.44%. It is also revealed that 40% of box waste provided the best composition for the application of the shoe soles.

“…The recent research findings show that trends are changing from FRP wrapper to infill material [8]- [13]. The world of the pipeline repair industry is now in progress to produce high-performance infill material [12], [14]- [16]. The goal is to reduce the usage of wrapper layers since it is costly and challenging to manage, particularly for damaged pipes situated in dense areas, the complexity of possible laminar failure and conservativeness in the existing design code for composite repair thickness [15], [17], [18].…”

The properties of the infill material are an important parameter in predicting the performance and behaviour of Fibre Reinforced Polymer (FRP) composite for effective design. This paper identifies the potential of Multi-walled Carbon Nanotubes (MWCNTs) as nanofiller in enhancing the performance of infill material. Two compositions of MWNTs at 0.1% and 0.5% of weight fractional were evaluated toward neat epoxy on tensile and lap shear test. By comparing MWCNTs-based modified epoxy grouts and neat epoxy grout, a significant increase in tensile strength was observed, especially with 0.5% of MWCNTs by almost 53.3%. While the inclusion of MWCNTs showed a comparable increment in shear strength in both 0.1% and 0.5% weight fractional by 13%. The image of morphologies showed that MWCNTs were well incorporated into the matrix, making the cross-section of the fracture rougher by sharing stress. This shows the potential of the MWCNTs in changing the properties of the modified epoxy grout, provided that the MWCNTs are appropriately dispersed throughout the resin matrix.

“…GNP involvement has a significant reinforcing effect and was effective in increasing ductility of the grout, reducing its brittle nature. This means that improved epoxy filling output is expected to be reliable and can minimize the sudden breakdown of the pipeline due to bursting [13].…”

The purpose of this research is to utilize graphite rods in use batteries to be processed into graphene oxide as a coating on steel to be resistant to corrosion. Liquid exfoliation and surfactant methods used to make Corrosion Penetration Rate (CPR) method for calculating weight loss. Corrosion monitoring by immersing samples of low carbon steel in a solution of 0.1 M NaCl for 2, 4, and 6 hours. Final results showed that low carbon steel samples have CP R values that have the smallest CPR is 0.5 gram graphite bars on using batteries + 25ml aquadest + 25ml H 2 SO 4 . The value of not exceeding the standard permissible rate (0.5 mm/ yr). Applications for this study showed that CPR of low carbon steel that coated using graphene oxide from graphite bars on using batteries more lower than CPR of steel with a coating in general (galvanized).
