“…The increment in void content is may be due to incompatibility between the phenolic resin and PALF and high percentage of fibre fraction were inadequate to mix with the polymer properly. According to researchers [29][30], incomplete wetting out of the fibres by the matrix would lead to the formation of voids. During impregnation of fibres into the matrix or during manufacturing of fibre reinforced composites, the trapped air or other volatiles exist in the composites [31].…”

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

ABSTRACT. Short carbon fibre (CF) and sawdust (SD) were dispersed in to the epoxy (EP) matrix in order to manufacture polymer hybrid composites using compression moulding technique. The mechanical properties of flexural properties of hybrid, compression moulded, chopped CF/SD/epoxy composites have been investigated taking into account the effect of hybridization by these two fillers. Hybridization with small amounts of SD makes these CF composites more suitable for technical applications. The simultaneous compounding of epoxy with two fillers was done to obtain a hybrid composite. This system is expected to have considerable mechanical properties, good surface finish and low cost. It has been found that the tensile properties of filled epoxy were higher than unfilled epoxy. By incorporating up to 30% (by mass) Carbon fiber (CF) and 10% sawdust (SD) namely S 3 sample flexural strength was increased by 12.5%. Thus it is shown that the durability of CF/SD filled epoxy composites can be enhanced by hybridization with small amount of CF. The hybrid effects of the flexural strength and modulus were studied by the rule of hybrid mixture.

“…are finding increasing usage in various industries as an alternative to synthetic fibers as these are abundantly available and form a renewable resource. Albuquerque et al (2000) reported that natural fibers are biodegradable, possess high toughness and high specific modulus, exhibit reduced tool wear and good thermal properties. Gowda et al (1999) developed untreated jute fabric reinforced polyester composites in which they reported that among all reinforcing natural fibers, jute has attracted Milewski and Katz (1980) have mentioned in their handbook that fillers are added to composites for economical and technical reasons.…”

The present work demonstrates the fabrication and properties study of Vinyl ester i.e. Bisphenol-A glycidyldimethacrylate (BisGMA) composites hybridized with 2-hydroxyethyl acrylate (HEA-10% w/w) grafted jute fiber and aqueous NaOH (5% w/w) treated coir pith used in various proportions and to characterize thereof. The mechanical and dynamic mechanical properties were measured in dependence of treated & untreated fiber as well as filler content. Composite with HEA grafted jute fiber and coir pith (15 wt%) exhibited maximum improvement in the above mentioned properties. Thermogravimetric analysis indicated the thermal stability of composites due to effective hybridization. The corrosive and water ingress properties of the composites were found to be negligible contributing to longer durability of the panels in moist and corrosive conditions.
