Aerobond Composites

The document summarizes the AERoBOND project which aims to develop an adhesive-free bonding technique for composite structures. The project is led by Frank Palmieri and involves researchers from multiple NASA centers. It discusses the growing aviation industry and need for lighter composite materials. Traditional adhesive bonding can cause issues like delamination. AERoBOND uses surface treatments to bond composites without adhesives, achieving near benchmark mechanical performance. The technique has potential applications in aircraft manufacturing and is being developed further through collaboration between NASA, material suppliers, and aircraft manufacturers.
