“…When talking about NFRC, it is crucial to understand the chemical composition and surface adhesive bonding between matrix and reinforcement that affect the mechanical properties of the composite. Natural fibres are known for their hydrophilic polar characteristic, which is against the non-polar hydrophobic matrix properties [4]. This condition lead to weak mechanical bonding between the matrix and reinforcement, resulting in poor mechanical properties of the composite produced.…”

Abstract. The focus of this study was to obtain the optimum alkaline treatment for pineapple leaf fibre and its effect on the mechanical and chemical properties, surface topography, heat resistivity, as well as its interfacial bonding with epoxy matrix. There were 6 different treatment conditions set for the fibre. The morphology of a single fibre observed under the Digital Image Analyzer indicates slight reduction in fibre diameter with increasing NaOH concentration. The Scanning Electron Microscope (SEM) results show the deteriorating effect of alkali, which can be seen from the removal of impurities and increase in surface roughness. The mechanical analysis indicates that 6% NaOH treatment with 3-hour immersion period yielded the highest tensile strength. The adhesion between single fibre and epoxy resin was analysed through the micro-droplet test. Alkaline treatment results in better mechanical bonding between fibre and epoxy resin. It was found that 6% NaOH treatment with 1-hour immersion yielded highest interfacial shear stress. However, as NaOH concentration went above 6 %, the fibre started to show reduction in mechanical properties, as well as fibre-matrix interlocking. The TGA analysis implies that alkaline treatment improved the thermal stability and heat resistivity of the fibre.

Abstract. Application of composite materials as a alternative materials is developed, The most of composite material is polymer matrix composite (PMC), with the polymer as a matrix and the sintetic fiber such as fiberglass and fiber carbon as a reinforced, it can make a materials with intermediete mechanical properties such as strength, hardness and thoughness, between matrix and fiber. Since the synthetic fiber was dangerous for human, so recenly developing natural fiber composite with advantages of natural fiber is more environmentally friendly, and more cheap than synthetic fiber. Otherwise, natural fiber has stong enough when it use at interior automotive parts, such as dashboard. Some cars already use the natural fiber for the interior parts. The natural fiber has a big potential, especially pineapple in Indonesia, the pineapple production at East Kalimantan is 25 344 tonnes in 2014. It means a lot of leaves can be used for the natural fiber. Pineapple leaf fiber (Pineapple Leaf Fiber / PALF) has a pretty good tensile strength of 126 MPa, and Young modulus of 4405 MPa and has a cellulose content About a 70-80% cellulose, cellulose which has a crystalline structure, so it can be good reinforced for composite. The result of this experiment, the optimum value of tensile strength is 29.9648 MPa , at composite PALF -Alcalinitation 40%.

“…First, PALF has good tensile strength (400-1600 MPa) and modulus (59 GPa) due to its high cellulose content 70-82% and high degree of crystallinity [8]. Second, since pineapple can be cultivated throughout the South-East Asia, it is possible for significant domestic production of PALF [23]. Third, PALF has already been used as a reinforcement to strengthen LDPE, rubber, thermosetting polyester, polyhydroxylbutyrate (PHB) and polyester amide [24].…”

Abstract. Pineapple leaf fibre (PALF) was hybridized with kenaf fibre in order to achieve superior physical and flammability performance. The mixing effects of kenaf fibre and pineapple leaf fibre in phenolic composites are evaluated at various fibre ratios and investigated various physical properties such as density, void content water absorption, thickness swelling and flammability. Pure kenaf fibre composite showed lowest void content, water absorption and thickness swelling while pineapple leaf fibre revealed the opposite trend. After adding pineapple leaf fibre in kenaf composites, it absorbed more moisture and developed more void contents. Density of PALF composite was lower and kenaf fibre composite was highest but PALF/kenaf hybrid composite increased density with higher PALF. The flammability of hybrid composites were analysed by using UL-94 test method. Vertical and horizontal UL-94 test conducted to analyse fire resistance of composites from different angles. Phenolic resin is itself a fire resistant polymer and the percentage of polymer in all samples are fixed though ratios of both fibres pineapple leaf fibre and kenaf were change to analyse fire resistant of fibres and compatibility with polymers. The 70 % pineapple leaf fibre and 30 % kenaf fibre hybrid composites were very affective to improve the flammability of PALF/KF hybrid composites. 1.Introduction As far as the environment is the concern, renewable resources of materials are the best alternative material of good economic potential and protection of nature, since, the renewable resources are characterized as biodegradable and recyclable, lignocellulosic fibres belong to this category [1]. Nowadays, natural fibres as reinforced material have been increased considerably due its low price compared to synthetic fibers [2]. Waste management of lignocellulosic and renewable materials and poor mechanical strength and thermal stability of polymers can be improved by developing natural fibres reinforced polymer composites [3][4][5]. Some plants fibres have potential to be applied in industries as raw materials such as pineapple, kenaf, coir, abaca, sisal, cotton, jute, bamboo, banana, Palmyra, talipot, hemp, and flex [6][7]. Pineapple leaf fibre (PALF) is one of the waste materials in agriculture sector, which is widely grown in Malaysia as well as Asia. After banana and citrus, pineapple (Ananas comosus) is one of the most essential tropical fruits in the world [8]. Natural fibres influenced mechanical strength due to chemical composition such as to cellulose, hemicellulose and lignin and its orientation and some other factors such as type of plant, environmental factors during growth as well as extraction methods used [9]. Usage of natural fibre can replace synthetic fibres to minimise health hazards, low density and high flexibility [10].Recently, polymer hybrid composites have become the attraction into production of mechanical stable and renewable products [11]. Polymer hybrid composites are formed by incorporating two and
