Mechanical Properties of Bio-Composite Natural Rubber/High Density Polyethylene/Mengkuang Fiber (NRHDE/MK):

In this study, the effects of long-term natural atmospheric ageing on the thermal properties of chicken feather fibre reinforced poly(lactic acid) biocomposite materials having chicken feather fibre mass content of 2, 5, and 10% were investigated. Chicken feather fibres, which are bio-based reinforcement material, and poly(lactic acid), which is bio-based matrix material, are compounded with a twin-screw extruder and injection-moulded; hence, the biocomposite material is produced. The effect of long-term natural atmospheric ageing on the thermal stability, crystallization, and melting behaviour of the biocomposite materials were analysed by thermogravimetric, derivative thermogravimetry, differential thermal, and differential scanning calorimetry analyses. In addition, the fracture surface of the samples was examined in depth by scanning electron microscopy analysis. The experimental results show that the long-term natural ageing process decreases the thermal stability values of the biocomposite materials and increases the glass transition temperatures and degree of crystallinities.

Investigation of long-term ageing effect on the thermal properties of chicken feather fibre/poly(lactic acid) biocomposites

In this present work, effects of interlamina fibre orientation on the tensile properties of composites were studied and the results were discussed The varying types of fibre oriented composites were prepared using the compression moulding technique at a pressure of 17 MPa The different types of oriented composites investigated were 90°/0 ° /90 °, 0 ° /90 ° /0 °, 90 ° /0 ° /0 ° /90 °, 0 ° /45 ° /0 °, 0 ° /90 ° /45 ° /45 ° /90 ° /0 °, 0 ° /45 ° /90 ° /90 ° /45 ° /0 ° and these composites were subjected to tensile testing according to ASTM: D3039-08 The sisal fibres were arranged in various angles with the help of specially designed mould It was found that the tensile strength of sisal fibre composites improved when 0 ° oriented fibres were positioned at the extreme layers of the composites compared to 90 ° oriented fibres The highest tensile strength among the types of composites was observed for 0 ° /90 ° /0 ° The scanning electron microscopy (SEM) analysis was performed to understand the interphase adhesion mechanism

Effect of inter-laminar fibre orientation on the tensile properties of sisal fibre reinforced polyester composites

Firstly, a brief overview of sisal fibres, including global sources and availability, chemical compositions, key properties, extraction and quality control is given. Their multi-scale structures and dimensional parameters are revealed by micro-observation, and their mechanical properties are measured a by single fibre tensile test. Several theoretical models are proposed and the results are compared with experimental values. Secondly, manufacturing techniques of sisal fibre-reinforced thermoplastics and thermosets are introduced. Effects of fibre surface treatments and moisture absorption on the interfacial shear strength, interlaminar shear strength and interlaminar fracture toughness are investigated. Mechanical properties, moisture absorption behaviour, and effects of moisture absorption and UV light radiation are revealed. Finally, current applications and further research aspects are proposed.
