Abstract
Composite materials are used in the fan blades of advanced high bypass ratio aero-engines, and resistance to sand erosion is of significant importance for the design of these blades. This study investigates the sand erosion behavior of carbon fiber reinforced polymer (CFRP) composites under distinct impact velocities and erosion durations using rotary arm erosion testing apparatus. The damage evolution mechanism of CFRP laminates under sand erosion is quantitatively analyzed, while residual mechanical performance is also assessed. The experimental results show that continuous sand erosion typically results in erosion pits at the impact center and abrasion bands on the surface of CFRP laminates. It is found that as the erosion velocity increases, both the material strength and stiffness decrease significantly, with peak reductions of 64.7 % in tensile strength and 46.2 % in elastic modulus observed at the maximum tested velocity (200 m/s). An analytical model was developed to characterize the relationship between residual tensile strength and erosion damage parameters, which demonstrates good agreement with experimental results, with an average error below 7 %. The findings provide foundational experimental data on the erosion resistance and residual tensile properties of CFRP laminates, supporting the design and reliability assessment of erosion-resistant structures.
期刊介绍:
Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development.
The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
