“…As a result of the OH absorption band, the UPKCF30 and TPKCF composites exhibited broad bands in the 3300 cm −1 regions. Due to the elimination of lignin and contaminants during alkali treatment, a corresponding drop in the intensity of all other peaks has also been seen in alkali-treated spectra [ 55 , 56 , 57 ]. The band appearing around 3000 and 2800 cm −1 corresponds to the C-H absorption band.…”

The manufacturing of materials, in conjunction with green technology, emphasises the need to employ renewable resources to ensure long-term sustainability. Re-exploring renewable elements that can be employed as reinforcing materials in polymer composites has been a major endeavour. The research goal is to determine how well palm kernel cake filler (PKCF) performs in reinforced epoxy composites. In this study, PKCF with 100 mesh was mixed with epoxy resin (ER) in various ratios ranging from 10% to 40% by weight. Hand lay-up with an open mould is proposed as a method for fabricating the specimen test. Surface modification of PKCF with varying concentrations of NaOH (5 wt.% and 10 wt.%) will be contrasted with the untreated samples. Using Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC), the effect of alkaline treatment will be examined. The tensile and maximum flexural strength of the untreated PKCF/ER composite were determined in this work, with a 30 wt.% of PKCF having the highest tensile strength of 31.20 MPa and the highest flexural strength of 39.70 MPa. The tensile and flexural strength were reduced to 22.90 MPa and 30.50 MPa, respectively, when the filler loading was raised to 40 wt.%. A 5 wt.% alkali treatment for 1 h improved the composites’ mechanical characteristics. Lastly, an alkali treatment can aid in the resolution of the problem of inadequate matrix and filler interaction. Alkaline treatment is a popular and effective method for reducing the hydroxyl group in fillers and, thus, improving interfacial bonding. Overall, palm kernel cake is a promising material used as a filler in polymer composites.

The amount of residues generated by agriculture, industrial, or urban activities continuously increases and, consequently, demands several methods for their correct management. The incorrect disposal can cause, in specific cases, environmental contamination by heavy metals or leaching as well as promote the spread of diseases as insect proliferation. Commonly, landfilling, incinerating, composting, or energy/fuel generation can control the disposal or reuse of residues. Among the methods for the reuse of wastes, the incorporation of residues as fillers in polymer composites has emerged as a distinct field. Some composites can potentially mitigate leaching compounds or improve mechanical, thermal, and acoustic properties. However, these improvements are a challenge to promote the use of waste fillers. Thus, this study aims to provide a state of view regarding a variety of wastes used as fillers in polymer composites and different methods to reach mechanical reinforcement as well as improve thermal conductivity and acoustic attenuation for future researches.

“…During mechanical testing, the double-layered areca frond composites showed higher tensile strength of 20.51 MPa for 10% NaOH with alkali treatment, the areca frond composites were 5 layers, and the age was 6 years. Mechanical properties such as tensile strength and flexural strength were found to increase with an increase in the number of layers and the concentration of NaOH treatment up to 10% [14].…”

Technological advances in material aspects are always increasing, and one of the applications of natural fibers as a matrix in composite materials has begun to be widely used. Composite materials have mechanical properties that are sturdy, corrosion resistant, and concise, and can be used as a substitute for metal materials. Areca palm fronds are part of the areca palm tree which are widely used as storage media because they are durable and weather resistant. The aim of this study was to determine the tensile strength of areca nut composites without alkali treatment combined with epoxy. Tensile test based on ASTM D3039 test standard. The test results showed a maximum tensile strength of 4839886.67 N/m2 or 4.84 MPa, and a modulus of elasticity of 114148270.5 N/m2 or 114.15 MPa. According to the JIS A 5905 standard, it meets the specified requirements, namely elastic strength of 32 MPa and tensile strength of 0.4 MPa.
