Summary: This study evaluates the failure mechanisms of plain glass, basalt fiber reinforced composites, and glass/basalt hybrid composite under artificial seawater conditions. The results show that hybrid laminates with sandwich-like and alternating sequencing exhibit superior mechanical properties and aging resistance compared to plain laminates. The failure analysis indicates that seawater exposure causes fiber breaking, matrix cracking, and debonding due to fiber-matrix interface degradation.

Summary: This paper proposes a novel in-situ experimental approach using micro-cantilever tests to characterize the interface of a carbon-epoxy unidirectional composite system. Computational models were implemented to validate the experimental results and investigate the interface debonding behavior under different damage modes. The validated model can effectively assess the proposed experimental approach in interface characterization. Overall, this approach provides a valuable tool for studying fiber-reinforced polymers and contributes to the development of more accurate predictive models.

Summary: This article presents a study on the LVI and CAI response of plain carbon fiber composite laminates, investigating the post-impact damage propagation in carbon/epoxy and glass/epoxy hybrid laminates under compression using experiments and numerical models. Low-velocity impact tests were conducted at different energy levels, followed by displacement-controlled compression tests. X-ray computed tomography was used to analyze the damage initiation and propagation. The results were validated using finite element models simulated with ABAQUS/explicit. The study also examined the impact of energy levels and stacking orientation on post-impact damage propagation by analyzing strain maps and stress-strain histories.

Summary: The production of lightweight vehicles is driven by the global challenges of fuel economy enhancement and greenhouse gas emissions reduction. Lightweight materials, such as fiber-reinforced plastics (FRP) composites, are being developed to replace conventional materials like steel and cast iron to achieve fuel efficiency and CO2 emission reduction. However, the damage of FRP composites under impact loading is a critical factor that affects their structural application. This paper focuses on the use of high-strength glass fibers as the reinforcing member to develop a car bumper beam, discussing its mechanical performance and manufacturing techniques. Based on literature studies, glass fiber-reinforced composite (GRP) shows more promise in the automotive industry compared to conventional car bumper beams.

Summary: In this study, hybrid AA2024 - Si3N4 - SiC - graphite alloy composites were fabricated using the stir casting method, and their physical, mechanical, thermal, thermo-mechanical, fracture toughness, and sliding wear properties were evaluated. The results showed that the density and material stability of the alloy composites improved with reinforcement content, while porosity and thermal conductivity decreased. The mechanical characteristics significantly improved with the addition of reinforcement, especially in the case of 6 wt.% Si3N4 particulate composite. The wear performance was also improved with higher Si3N4 particulate content, resulting in lower specific wear rate and friction coefficient.
