“…These three ranges of decrease in mass for several natural fiber-epoxy composites have been reported before [10,23,24]. FA Fauzi et al divided the weight loss process of natural fiber-epoxy composites into two stages: (1) weight loss happened due to the vaporization from the fiber, (2) the weight loss due to decomposition of cellulose at 265 to 595 °C [25]. Comparing to our results, the weight loss in stage (2) should be a combination of fiber and epoxy decomposition.…”

The aim of this study is to analyze the thermal properties of sago fiber-epoxy composite. The sago fiber-based composite has been prepared using epoxy resin as the matrix, via a simple mixing followed by compression. The compression process includes hot compression (100 • C/10 kgf cm −2 ) and cold compression (ambient/10 kgf cm −2 ). The composite series was prepared with 9%, 13%, 17%, 20%, and 23% (w/w) of epoxy resin. Microstructures of all materials used were observed using an SEM (scanning electron microscope) instrument. The thermal properties of the composite and its components were examined through TG/DTA characterization. The samples were heated using the heating rate of 10 • C/min from room temperature to 400 • C, except for epoxy resin, which was heated to 530 • C. TG/DTA results depict three stages of thermal processes of sago fiber-epoxy composite: evaporation of water molecules at below 100 • C with the peak point within the range of 51.3 and 57.3 • C, the damage of sago fiber within the range of 275 and 370 • C with the peak point within the range of 333.3 and 341.3 • C and the damage of epoxy resin at above 350 • C with the peak point at 376.2 • C.Fibers 2020, 8, 4 2 of 13 seed fibers (cotton, kapok, and coir), and other types, which may include wood and roots [5]. The aim in developing natural fiber-based composites is to replace materials owing to similar properties [6][7][8].Natural fiber composite polymers have been extensively used in several fields. The application of natural fiber composite polymers depends on their properties, because a specific application normally needs specific physical, mechanical, electrical, and thermal properties. The following are six fields in which natural fiber composite polymers have been used, followed by examples of application for each field: (1) civil (fire-resistant concrete); (2) mechanical (gear pair); (3) automobile (body part); (4) aerospace (aircraft parts); (5) biomedical (dentistry and orthopedic); and (6) marine (marine propeller) [8].Aside from depending on the type and composition of its components, mechanical and thermal properties of natural fiber composite polymers are strongly correlated to their structures, which are influenced by procedures during preparation. One popular technique used in natural fiber composite polymers preparation is by compression, in order to make a dense composite. Microcavities often formed within the composite due to spaces between fibers that are not fully filled by adhesive. Several studies have been conducted to understand the relationship between mechanical properties and/or thermal properties with microstructures. Correlation between mechanical properties and microstructure allows for a study of failure evolution on carbon fiber reinforced polymer (CFRP) and epoxy resins by using scanning electron microscopy (SEM) [9].To use composite materials effectively, it is important to study the mechanism of damage for composite materials. Several studies on the mechanism of mechanical and thermal damage have been reporte...

“…Fourier-transform infrared spectroscopy (FTIR) analysis revealed that mengkuang leaf contained the same functional group as found in natural fiber such as kenaf, jute and flax, suggesting its amazing potential as the reinforcing fiber [18]. Fauzi et al [19] found that the MLF was a good reinforcement in polyester.…”

“…Due to its hydrophilic nature, natural fiber composites can cause several problems, such as swelling, dimension changes and voids [22]. To remove excessive content of hemicellulose, pectin, lignin and ash, alkaline treatment such as sodium hydroxide (NaOH) can be applied, which is a common surface treatment for MLF [19,23]. The clean surface of the fiber could significantly improve the adhesion between the fiber and matrix [24].…”

Due to environmental concerns, plastic recycling and natural fiber composites have been given more attention lately. In Malaysia, mengkuang leaf fiber (MLF) has been identified as a potential candidate to be used as a reinforcing fiber. The combination of recycled polypropylene (r-PP) and MLF could result in an inexpensive and sustainable composite. However, the mechanical properties of this composite have not been fully studied. The aim of this work was to evaluate tensile, flexural and impact properties of r-PP/MLF composites with and without sodium hydroxide (NaOH) treatment and maleic anhydride-grafted polypropylene (MAPP). The composite consisted of 60 wt.% of r-PP and 40 wt.% of MLF. The composite was compounded by twin-screw extruder and test specimens were fabricated using an injection molding process. Generally, the tensile and flexural properties showed improvements, especially those with MAPP and alkaline treatment, compared to neat r-PP. Improvements in tensile strength and modulus of approximately 28% and 224% were achieved for r-PP/Treated MLF/MAPP composite respectively. However, an adverse effect was observed in the impact strength of the composite, which was expected due to the nature of short fiber employed in this work.
