In an unfilled polymer, stress is distributed relatively uniformly through the matrix. But once fillers are added, the situation changes. Each particle becomes a checkpoint, a barrier, or a bridge. Some fillers interrupt stress transfer. Others redirect it. And some create highly efficient pathways that allow loads to travel through the structure more effectively. This is why particle geometry matters. A spherical particle, a platelet, and a fiber do not guide stress in the same way. Two compounds may contain the same polymer and the same filler loading. Yet their internal stress distribution can be completely different. And...
