“…In this context, a large amount of studies have been published relating to the influence of fibre length and orientation (Peters, 1997;Lionetto et al, 2014). As with inorganic fibres, the highest stiffness and tensile strength for natural fibres was found when the fibres are orientated unidirectional and the tensile tests were conducted in fibre direction (Ben et al, 2007;.…”

In this study, the biodegradable behavior of green composites under different pH (concentration of hydrogen ion) soil and environmental temperature was investigated. The biodegradation test was conducted in 90 days. The environmental temperatures were room temperature (RT) and 50°C. The acid soil (pH 4.2), neutral soil (pH 5.5) and alkali soil (pH 7.4) were used as environmental soil. A quasi-static tensile test was conducted after the biodegradation test. As a result, the mass rate of green composites in all soils at RT almost did not change by 60 days. After that, their mass rates decreased. The mass rates of green composites in all soils at 50°C moderately decreased with an increase of biodegradation time by 60 days. After that, their mass rates rapidly decreased. In the case of all soils at RT and 50°C, the tensile strength and Young's modulus of green composites decreased with an increase of biodegradation time by 60 days. After that, they did not change any more. The tensile strength of the composites in all soils at 50°C decreased with an increase of biodegradation time by 60 days. After that, they moderately decreased except for acid soil. Young's modulus of composites in all soils for 30 days at 50°C rapidly decreased. After that, their Young's modulus moderately decreased. Their results implied that the tensile property of green composites decreased due to the biodegradation of PLA resin in soils at environmental temperatures.

“…[9] The heat-resistant tensile properties of this green composite were examined. [10] The aim of this study is to develop a fabrication method for green composites used woven fabric of 150 mm width as reinforcement by a pultrusion molding. These green composite sheets can be continuously fabricated and can be treated an intermediate material such as carbon fiber reinforced plastic (CFRP) prepregs.…”

Conventional fiber reinforced plastics (FRPs) have some problems in the case of disposal. Their combustion disposal discharges the carbon dioxide in the air because resins of FRPs are made of fossil fuel. In the case of disposal into the ground, these FRPs remain semi-permanently without decomposing. Therefore, green composites are now developed and are studied as one of less the environmental burden materials. In this study, two kinds of continuous green composite sheets, which were composed of Kenaf fibers or Linen fibers as reinforcement and biodegradable poly butylene succinate (PBS) resin as a matrix, were fabricated with a pultrusion molding. Since the PBS resin is a thermoplastic resin, the PBS/KENAF or PBS/ LINEN composite sheets can be treated as intermediate materials such as Carbon Fiber Reinforced Plastic prepregs. In order to apply the PBS/KENAF or PBS/LINEN composite sheets to structural components, quasi-isotropic plates and cylindrical shells were fabricated and evaluated.
