Effect of silane surface treatment on interlaminar failure of aged glass fiber-pet core sandwich composite

The study of the mechanical properties of fiber-PET core sandwich composites aims to analyze the mechanical characteristics of these materials, which feature a core made of Polyethylene Terephthalate (PET) fibers. Sandwich composites are widely used across various industries due to their lightweight and high-strength properties. The PET core fiber offers potential advantages such as low cost, recyclability, and environmental friendliness. The process starts with fabricating the glass fiber PET core sandwich composite. Mechanical properties, including tensile strength, hardness, impact resistance, flexural strength, water absorption, and thermal conductivity, will be evaluated through experimental testing. Additionally, the study will investigate the effects of core density, fiber orientation, and bonding between layers on the mechanical performance. Understanding the mechanical behavior of glass fiber-PET core sandwich composites will provide valuable insights for their application in industries such as automotive, aerospace, marine, and construction.
