“…Natural fibers are preferred due to its advantages such as low cost, low density, low abrasion towards tools and its degradability compared to petroleum based product [7][8][9]. The studies regarding natural fiber reinforced composite focused on the interface between matrix and filler, morphologies, mechanical properties and thermal properties [10][11][12][13][14][15][16]. The concern for environmental issues such as ingestion of plastic by animals has sparked the necessity to study about natural fibres to replace synthetic fibres [17].…”

The performance of mengkuang leaf fiber (MLF) reinforced low density polyethylene (LDPE) composites with different fiber volume and different mesh sizes were studied. The fibre weight percentage used in the research were 10%, 20%, and 30% and for different fiber size were <0.5 mm, 0.5-1 mm, and 1-2 mm. The extrusion and hot compression molding were used to fabricate the specimen testing. The mechanical testing performed were impact and flexural test which follows the ASTM standards D790-10 and Izod D256. It was observed that by increasing the fiber volume and fiber size, the flexural strength and the flexural modulus were increased. However the impact strength shows different results for fiber length and fibre content where the impact strength increases with fibre length but decreases with the increase of fiber content. It can be concluded that the 30% fibre content is the optimum fibre loading for the MLF-LDPE composite with the flexural strength of 12.31 MPa, flexural modulus of 378.88 MPa and impact strength of 589.86 J/m whereby the 1.0-2.0 mm fibre length is the best fibre size for the MLF-LDPE composite with the flexural strength of 12.86 MPa, flexural modulus of 267.76 MPa and impact strength of 1511.57 J/m. In future studies fibres should undergo surface modification to increase the available surface area for reaction to increase the strength of the composite by better mechanical interlocking.

“…It is also clear that all fl exural strengths in various formulations were reduced signifi cantly in wet conditions. interfacial bonding is determined by several factors, such as the nature of fi ber and polymer components, the fi ber aspect ratio, the processing method and the treatment of the fi ber (MIRMEHDI et al, 2014). Result of tensile strength of rice stalk/thermoplastic composites is shown in Figure 4.…”

“…Any substance that contains carbohydrate polymers, cellulose and hemicellulose and an aromatic polymer, lignin, is a lignocellulosic. Lignocellulosic includes types of wood, agricultural crops, like kenaf; agricultural residues, such as bagasse, corn stalks and rice stalk, agricultural pruning residue such as date palm fronds and other plant substances (MIRMEHDI et al, 2014). In general, what is true for wood is also true for other lignocellulosics even though they may differ in chemical composition and matrix morphology, in fact these kind of natural lignocellulosic fibers are available in many different forms and produce different properties when added to thermoplastics (GILBERT, 1994;SANADI et al, 1995;ZAINI et al, 1995).…”

ABSTRAT: Thermoplastic composites made with 45, 60 and 75% of rice straw as filler and two types of thermoplastics, virgin polyethylene (PE) and polypropylene (PP) were evaluated. The final boards were made with and without maleic anhydride modified polypropylene (MAPP) at 2% of the total weight of each specimen. The flexural and tensile strengths were measured for dry composites and also measured after 24 h of water immersion of the composites (wet condition). By increasing the filler content, the flexural and tensile strengths and also the density of the specimens decreased. The type of matrix (PE or PP) did not affect significantly the flexural strength, but PP led to higher values of tensile strength for low fiber loadings (45% and 60%). Coupling agents increased the flexural and tensile strength. After water immersion, modulus of elasticity and modulus of rupture were decreased, while tensile strength was less influenced. COMPÓSITO TERMOPLÁSTICO/PALHA DE ARROZ: EFEITO DA CARGA DE ENCHIMENTO, TIPO DE POLÍMERO E ABSORÇÃO DE UMIDADE NO DESEMPENHORESUMO: Foram avaliados compósitos termoplásticos feitos com 45, 60 e 75% de palha de arroz como material de enchimento e dois tipos de termoplásticos, polietileno virgem (PE) e polipropileno (PP). As placas finais foram feitas com e sem polipropileno modificado com anidrido maleico (MAPP) a 2% do peso total de cada amostra. As resistências à flexão e à tração foram medidas para compósitos secos e também medidas após 24 h de imersão em água dos compósitos (condição úmida). Ao aumentar o teor de enchimento, as resistências à flexão e à tração e também a densidade dos matérias diminuíram. O tipo de matriz (PE ou PP) não afetou significativamente a resistência à flexão, mas o PP levou os maiores valores de resistência à tração para baixas cargas de fibras (45% e 60%). Os agentes de acoplamento aumentaram a resistência à flexão e à tração. Após a imersão em água, o módulo de elasticidade e o módulo de ruptura diminuíram, enquanto que a resistência à tração foi menos influenciada.
