Abstract

Journal of Thermoplastic Composite Materials, Ahead of Print.
Current understanding of carbon fiber-reinforced PETG (PETG-CF) honeycomb structures remains limited, with their mechanical properties and failure mechanisms insufficiently characterized across a wide operational temperature range from −20°C to 65°C. This ...
