Final answer:
Macro composites are traditional composites with the largest filler particles, providing great strength due to their large-scale reinforcement structures, such as fibers, within a matrix.
Step-by-step explanation:
The conventional or traditional composites that contain the largest filler particles and provide the greatest strength are known as macro composites. These composites are characterized by their large-scale reinforcement structures, such as fibers or particles that are significantly larger than the microscopic scale. The constituent materials in these composites include a matrix (binder) which surrounds and supports the reinforcement materials by maintaining their relative positions. The reinforcements impart their unique mechanical and physical properties to enhance those of the matrix.
Examples of traditional composites include polymer-matrix composites, which consist of reinforcing fibers embedded in a polymer matrix, and metal-matrix composites, where the reinforcement is embedded in a metal or metal alloy matrix. The engineering application of these composites ranges from building and construction to the automotive and aerospace industries, due to their tailored properties that combine the strength of the reinforcement with the toughness of the matrix.
