“…carbon or glass) can be attained by combining them with high strain to failure properties (e.g. aramid, polyester or polyamide polymers), owing to the reason that this process (hybridization) mixes the superior mechanical characteristic of high stiffness reinforcements with the superior impact resistance of ductile fibers [99]. The mechanical properties and failure profile of these composites as a function of the ratio between various reinforcements and dispersion nature were studied and discussed by numerous researchers.…”

“…2D‐continuous fiber‐based composite laminates are, on the other hand, pliable to delamination and critical failure propagation under transverse impact loads owing to the absence of through‐the‐thickness fiber . Unlike composites with continuous plain weave woven fabrics which are more prone to delamination under transverse impact load, composites with chopped fibers are randomly oriented in the through‐the‐thickness direction.…”

This article investigates the effect of multiphase fiber system based on plain weave woven fabrics and chopped short fibers in glass/epoxy composite laminates on low‐velocity drop weight impact and quasi‐static tensile after impact (TAI) behaviors. In this regard, glass/epoxy composites with two stacking sequences (intercalated and sandwich‐like lay‐ups) were tested and compared with homogeneous standard composites fabricated with either only woven or only chopped fibers. In all the samples with multiphase fiber system, the amount of woven and chopped glass fibers were equal (4 layers and 3 layers, respectively), while stacking sequences were different. This enabled us to investigate the associated influences of fiber architecture and stacking sequence on low‐velocity drop weight impact and TAI behavior of the glass/epoxy composite laminates. All the glass/epoxy samples were impacted at four various impact energy levels, particularly 2, 4, 6, and 8 J. Results depicted that fiber architecture and stacking sequence played a vital role in low‐velocity drop weight impact and TAI behavior (i.e., damage degree, absorbed energy, peak contact force, residual deformation, residual tensile strength, displacement to ultimate failure, and failure profile) of the glass/epoxy samples. The results depicted that the sandwich‐like lay‐up configuration presented superior impact properties and damage tolerance capabilities at low impact energies (up to 4 J). On the contrary, intercalated lay‐up arrangement suited better to withstand widespread damage generated by higher impact energy levels (6 and 8 J), because they enabled a more efficient redistribution of low‐velocity impact damage in the composite.

“…Owing to ease of online or real‐time monitoring of dynamic change (i.e., damage propagation) within heterogeneous anisotropic laminated composites, the AE monitoring technique has gained considerable interest in recent times for being considered as a novel non‐destructive technique with many advantages than conventional NDT techniques which provide information regarding stagnant defects. Moreover, this technique enables real‐time localization of the damage on the repaired laminates . Numerous literatures can be found on AE amplitude‐based discrimination of failure modes.…”

This article investigates the compressive response of damaged glass/epoxy composite laminates repaired using hybrid external patches. Hybrid external patches based on glass and Kevlar woven fabrics bonded on both faces of the damaged parent laminate were considered. Five different kinds of plain weave woven fabrics with a different ratio between glass and Kevlar fibers (100/0, 75/25, 50/50, 25/75, and 0/100) were used as the external patches. The intention of using these hybrid patches is to build up a patch of optimum stiffness that facilitate to restrict the critical adhesive or cohesive failure on the joints unlike high stiff glass fibers or extensive fiber micro‐buckling of the external patches unlike low stiff Kevlar fibers under compression loading and consequently to produce repaired laminates with a strain to failure and residual strength nearly close or similar as that of virgin or normal components. The virgin and damaged specimens were taken as the reference specimens for comparison of residual mechanical properties and damage mechanisms. Damage evolution and the failure progression of the repaired glass/epoxy specimens were monitored using real‐time Acoustic Emission (AE) monitoring technique. Specimens repaired with the equal volume fraction of glass and Kevlar fibers in the external patches presented the most favorable residual compressive response by effectively releasing the stress concentration in the damaged area.
