Abstract
Carbon fibres is the most recent popular material use for composites purpose by many industries due to its superior mechanical properties but due to massive production in industry has created waste and environmental effect. Hence, recent study suggested and carried out the pyrolysis process as one of the method to reclaimed the carbon fibre. However, different temperature and dwelling time of pyrolysis affect the quality of rCF. Therefore, tensile testing analysis and statistical analysis was use to determine the mechanical properties of the reclaimed carbon fibre. The aim of this study is to evaluate the mechanical strength and modulus of the received pyrolysed reclaimed carbon fibre (rCF). The single fibre tensile testing was carried out on the rCF and rCF industry scale via standard ASTM C1557 at the gage length of 25 mm and 40 mm. From the stress-strain analysis, the strength of rCF for both gauge length was between 1.23-2.48 GPa. The rCF strength distributions were strongly correlated with the diameter with distribution strength values of the tested fibres, and from Weibull analysis is between 1.4-2.8 GPa. The variation of the Weibull parameter depended on the gauge length. Scanning electron microscopy (SEM) evaluation of the failure stress revealed the presence of fracture inducing flaws located at the surface or in the interior of the fibre
