Three different hybrid architectures, manufactured by varying the percentages and lay-ups of the constituent fiber tows, were examined to understand the effect of hybridization on the resulting performance enhancement, including the bending modulus, flexural yield stress, and strain to failure.
The flexural modulus, flexural strength and strain to failure were also predicted by finite element analysis.
An increase in Si10 content led to an increase in Young's modulus and a concomitant decrease in flexural strain.
The hybridization with low- and high-modulus fibers was employed to increase deformability and flexural strain capacity of the ECC composite.
Moreover, the values for compressive and flexural strain as well as dynamic elasticity modulus increase when increasing irradiated-fiber concentration.
The effectiveness of a range of different potential GRAS plasticisers was assessed by mechanical characterisation based on flexural and indentation measurements to determine parameters such as flexural strain and stress, fracture energy and Young's modulus.
Tensile strength, tensile modulus, flexural strength, flexural modulus and HDT increased after rPET fiber incorporation while strain at break, impact strength and fatigue life decreased.
The results indicate that the flexural strain and flexural strength were significantly improved without impairing other flexural properties such as the flexural modulus, illustrating a great potential of the proposed concept in toughening of textile reinforced pCBT composites.
The outputs consist of the ultimate tensile strength, elongation, tensile modulus, flexural strength, flexural modulus and hardness for the particle sizes: 150, 212, 250 and 300 µm.
