Polymer Matrix
A Polymer Matrix is a special type of material used to make strong, lightweight products by combining plastics with other materials like fibers or particles. Think of it like making a chocolate chip cookie, where the dough is the polymer (plastic) and the chips are reinforcing materials. Companies use these materials to create everything from airplane parts to sporting goods because they're both strong and light. You might also hear these called "composite materials" or "reinforced plastics." When candidates mention Polymer Matrix experience, they're typically talking about designing, testing, or manufacturing these enhanced materials.
