Plastics Welding: The Choices Widen

The many ways to weld plastics include well-established technologies such as heat staking, hot-plate, ultrasonic and vibration welding, recently adopted methods like infrared and laser welding, and technologies looking for applications, such as microwave welding. You'd think that would be enough; you'd be wrong.

Self-Healing Materials

When developing structural materials, engineers must consider two fundamental design concepts: damage prevention and damage management. The latter forms the basis of self-healing materials and is also the foundation for material development in nature. The paradigm is based on the notion that the formation of damage is not problematic so long as a subsequent, autonomous process of "removing" or "healing" the damage counteracts it.
