In orthosis design, what is the primary advantage of combining plastics and metal?

Combining plastics and metal in orthosis design primarily enhances strength and durability. This hybrid approach takes advantage of the inherent properties of both materials. Metals, known for their tensile strength and rigidity, provide structural support and can withstand significant loads and stresses. Plastics, on the other hand, are often lighter and can offer varying levels of flexibility depending on their formulation.

When these materials are used together, the resulting orthosis benefits from the robustness of metal while utilizing the lightweight and adaptable nature of plastics. This combination can lead to a more effective orthosis that offers not only superior support but also a level of comfort and adaptability that single material designs might lack. For individuals requiring orthotic support, this means they receive an aid that is sturdy yet not overly cumbersome, improving overall functionality and user experience.

The other options present characteristics that do not align as effectively with the advantages of combining these materials. Increased weight is counterproductive for orthotic devices, improved flexibility might be a benefit of using plastics alone, and while lower manufacturing costs could be a consideration, the main focus here is on the enhanced performance characteristics achieved through the strategic combination of materials.
