Composite materials, which have gained prominence in the aerospace industry due to their high strength-to-weight ratio, are vulnerable to delamination damage when struck by low-speed projectiles due to their low through-thickness strength. This paper presents the experimental evaluation of a composite plate subjected to low-velocity impact. The plates under discussion were constructed using a carbon fibre reinforced polymer laminate with a quasi-isotropic ply structure. Experiments were carried out using a conical-shaped impactor on carbon/epoxy laminated plates with three different orientations ([0/0] 4 s, [0/90] 2 s, and [45/0-45/90] s) that were put through two distinct impact energies (7 J and 14 J). Impact response is determined using drop-weight impact tests. The techniques of ultrasonic C-scan, field emission scanning electron microscopy (FESEM), and surface micrographs were integrated to provide a new and in-depth understanding of damage evolution and failure mechanisms in composite laminates. Damage resistance appears to decrease as impact energy increases. Furthermore, thicker laminates have lower absorbed energy but, on the other hand, more widespread delamination due to increased bending stiffness. Furthermore, quasi-isotropic laminates outperform in terms of damage resistance and increased energy absorption rates by 8 % to 15 %. The efficacy and logic of the suggested model were shown by a strong connection between experimental results.

“…Due to their unique properties, composite materials, which are made up of a combination of two or more different materials, have received a lot of attention in recent years. [1][2][3][4][5][6][7][8][9][10] Glass-fiber, carbon-fiber and basalt-fiber composites achieved by mixing fibers with polymeric resin can be demonstrated as the most common examples. [11][12][13][14][15][16] These fiber-reinforced composite materials are extensively utilized in many engineering fields such as aerospace, aviation and automobile due to their high strength, lightweight, stiffness, resistance to environmental and corrosive factors, design originality and production advantages.…”

Residual compressive strength of polyamide fiber‐reinforced epoxy composites after low‐velocity impact

In this study, polyamide fibers, which stand out with their excellent plastic deformation and energy absorption capacity, were used as reinforcement materials, and in‐house manufactured composite specimens were subjected to low‐velocity impact (LVI), compression after impact (CAI) and tensile tests. Within this scope, one and two repeated drop tests were performed under 3 m/s velocity to determine LVI responses and how impact number affects the dynamic properties. CAI tests were also performed at a 1 mm/min crosshead speed, and mechanical properties for non‐impacted, one‐impacted, and two‐impacted specimens were determined. As a result of the outstanding plastic deformation capacity of thermoplastic fabrics, it is concluded that polyamide composites exhibited quite large strains. Furthermore, it was understood from the tensile responses that tensile stresses were carried by the thermoplastic fibers in two different regimes and significantly high toughness was obtained. Moreover, reductions in the maximum compression loads, critical buckling loads and axial stiffness were observed due to degradation in structural integrity after impact loads. Additionally, the utilization of recyclable thermoplastic polyamide fibers as reinforcement material instead of conventional reinforcement materials such as carbon and glass fibers provide more environmentally friendly products.

“…As a result, regarding various types of composite laminates, many studies have been carried out to illuminate the impact damage mechanism as well as the deep negative effect of the LVI on the subsequent mechanical properties such as tensile test, [10] shearing, [11,12] bending [13][14][15][16] and compressive test. [17][18][19] The part of existing latest related research and their research contents are summarized and the first point to note is that even a tiny impact energy can lead to a significant decrease in the strength under various kinds of post-impact tests. In addition, the effect of LVI load on the post-impact behavior depends on a combination of multiple factors, such as original materials, the configuration of the specimens, and even size, and so forth.…”
