Conventional composite materials reinforced with continuous fibres display high specific strength but have a number of drawbacks including: the elastic-brittle behaviour, difficulties in producing defect-free components of complex shape with high-volume automated manufacturing processes, and inherent lack of recyclability. Highly aligned, discontinuous fibre-reinforced composites (ADFRCs) are

Topology optimization for transversely isotropic materials

2020/8/19We propose a topology optimization method for design of transversely isotropic elastic continua subject to high-cycle fatigue. The method is applicable to design of additive manufactured components, where transverse isotropy is often manifested in the form of a lower Young's modulus but a higher fatigue strength in the build direction. The fatigue constraint is based on a continuous-time

Isotropy vs Anisotropy

Metals, on the other hand, besides generally having relatively high strength, exhibit high thermal and wear resistance. Any objects used on a daily basis employ one or other forms of metal. It is used as kitchenware, medical equipment, tools, implants, building trusses, supports, as well as jewellery and base components for machines and vehicles [6].

Regenerated isotropic wood

2020/9/19RGI-wood has an isotropic uniform structure, which results in identical flexural strength and fracture toughness in both X and Y directions (Fig. 3a and d). As the wood particles are tightly bonded by surface cellulose nanofibers, the flexural strength and modulus can be up to ∼170 MPa and ∼10 GPa, respectively, which is remarkably higher than those of pine in both directions (Fig. 3b ).
