“…Composite materials are widely used in different applications due to their excellent properties such as lightness, flexibility, durability, low cost in the production processes and diversity. 1–3 In general, these materials are made from at least two different constituent materials, namely reinforcement and matrix elements which have different properties from each other. 4,5 The appropriate physical properties such as lightness, elasticity, heat and electrical conductivity, economy, etc.…”

“…of the composite laminates can be satisfied by selecting a suitable reinforcement element. 3,6 Meanwhile, the properties such as the interaction of additive materials (i.e. particles) with matrix, binding, appearance, compliance with ambient conditions, ensuring load and voltage transformation, and impact protection are determined by matrix material.…”

Recently, advanced composite materials have been widely used in numerous applications due to their superior properties. However, their sensitivities to damages during impact loading event limits their usage. In this regards, the influence of yarn hybridisation on the mechanical and thermal performance of composite laminates have been studied using low velocity impact, compression after impact (CAI), flexural and thermal conductivity tests. Two types of composite laminates were manufactured using hybrid yarns (S-glass and polypropylene [PP]) and S-glass yarns through the combination of commingling and core-wrapping methods and converted to non-crimp cross-ply preforms for both laminates. C-scan tests and cross-section microscopy examinations were adopted to identify the damaged areas of impacted laminates and explain the damage failures, which occurred during impact loadings. Results revealed that the hybrid laminates displayed higher damage area reduction compared to glass composites. Although the hybrid composite laminates illustrated considerably lower compressive strength, their residual compressive strength (damage tolerance) was significantly higher than glass composites. Fractography analysis has illustrated that the new damage failure modes such as intra-yarn cracks have been observed in the hybrid yarns laminates. These damage modes have contributed for higher energy absorpsion leading to an enhancement of the damage tolerance of the hybrid laminates. Furthermore, the incorporation of PP fibres resulted in a reduction of thermal conductivity of hybrid laminates compared to pure glass laminates.

Carbon fibers are the reinforcement of choice for high performance (advanced) composites. The fiber and matrix properties determine the various mechanical properties in and perpendicular to the fiber orientation in composites. However, for a given matrix the carbon fiber surface properties determine the quality of the fiber‐matrix interface, in which load transfer from the matrix to the fibers takes place. This article summarizes the surface properties of commercially available carbon fibers as well as the benefits of carbon fiber surface modification on the adhesion behavior between fibers and matrices.
