Abstract Quasicrystals (QCs) are a new class of functional and structural materials with unusual properties, which have quasi-periodic translational symmetry and non-crystallographic rotational symmetry. Due to the special arrangement of atoms, compared with traditional materials, QCs have high strength, high hardness, and high wear resistance, and can be used as a particle reinforcement phase of polymer or metal matrix composites to improve the performance of materials. QC composites are a special type of composites in which the high strength and hardness of QCs can effectively enhance the mechanical properties of the composites while maintaining the lightweight… More >

Abstract The aim of this work is to investigate the influence of a variety of plasma treatments on the surface properties of an epoxy-based composite material and to establish a relationship between these properties and the subsequent mechanical behaviour of adhesively bonded joints. To this end, specimens were subjected to three different types of plasma treatment: two short treatments (2min) of He and He plus O₂, and one long treatment (15min) of He plus O₂. The variation in surface energy of the composite specimens was examined in each case over a period of up to 3 days… More >
