Final answer:
Conventional or traditional composites with the largest filler particles that offer high strength are known as macro composites. Various types like ceramic-matrix, polymer-matrix, and metal-matrix cater to specific properties and applications.
Step-by-step explanation:
The conventional or traditional composites that contain the largest filler particles and provide the greatest strength are referred to as macro composites. These macro composites typically have larger filler materials, such as fibers or particles, that provide a high level of strength to the composite material. The categories of composites based on the matrix include ceramic-matrix composites, polymer-matrix composites, and metal-matrix composites. Each type takes advantage of different constituent materials to provide unique properties to the final composite, whether it be for heat resistance, strength, light weight, or other desired features. For example, fiber-reinforced polymers (FRPs), which often use glass fibers or carbon fibers, are well-known for their high strength-to-weight ratio.
