The use of fibers as reinforcements increases the resistance of the plastic or metal to rupturestress and increases strength while providing a product light in weight.
利用纤维作为加强材料增加了塑料或金属的断裂应力，增加了强度，降低了产品的重量。

Bond strength generally involves determining the stress required to rupture a bond formed by an adhesive between two metal blocks.
粘接强度试验通常涉及确定使两个金属块之间由粘合剂构成的粘接发生断裂所需的应力。
