Generative Design of Bioactive Orthopedic Composites for Fracture Repair Using an Integrated Conditional GAN–Transformer Framework: A Multi-Objective Approach
Abstract: Orthopedic composite implants for fracture repair must simultaneously satisfy conflicting mechanical and biological demands: high fracture toughness, sufficient compressive stiffness, and bioactive surface chemistry enabling osteoblast adhesion and mineralization. Existing design approaches rely on trial-and-error experimentation, yielding sub-optimal trade-offs between these objectives. This paper presents an integrated conditional Generative Adversarial Network–Transformer (cGAN-T) framework for fully computational, multi-objective generative design of hydroxyapatite (HA)-reinforced polymer composite microstructures targeting Orthopedic fracture repair.

Improving the Mechanical and Interfacial Properties of Bhendi Fiber via Chemical Surface Treatments
Abstract: Because of its primary benefits—moderate strength and stiffness, low cost, and being a renewable, degradable, and ecologically friendly material—natural fibers are believed to have potential use as reinforcing agents in polymer composite materials. Due to their inherent hydrophilicity, they have a tendency to retain moisture, which can impair or soften the fibers' adhesion to the surrounding matrix. This can have an impact on the performance of composite materials used in …
