Abstract

Composite materials have gained wide applications, including advanced technology and engineering applications. This is primarily due to many advantages composite materials provides which include specific strength and specific modulus. Strength, stiffness (modulus) and toughness are often desired in composite materials. However, strength and toughness are mutually exclusives; therefore, the challenge to retain these trio-mechanical properties in composite materials without sacrificing one for another have proved daunting. Contrary to human-made material is nacre which is a natural existing type of composite material that have been able to circumvent the challenge and retained the trio mechanical properties. Taking into consideration existing composite reinforcement technologies, fibre reinforcement and nanocomposite which have evolved and adapted to various applications yet to achieve composite material that is sufficiently strong and stiff while maintaining toughness. Therefore, through modelling analysis, this research assesses the feasibility of fabricating composite material with enhanced strength and stiffness while maintaining toughness. An approach which involves identifying an ideal type of reinforcement filler with adequate strength and stiffness to enhance composite material which could be manoeuvred such that the reinforcement filler aspect ratio is within proximity to the composite material system critical aspect ratio for toughness to be maintained.
