The ACMs are also known as advanced polymer matrix composites and usually characterised by high strength fibres and high stiffness. These are, as compared to other materials, bonded together by weaker matrix. The thermosets and thermoplastics are also ACMs. While thermoplastics require no chemical reaction, thermosets require an additional curing agent to produce finished parts.
All the statements given are true.

Incorrect Statement:
Advanced Composite Materials are generally characterised by high strength fibres and high stiffness.

Explanation:
- Advanced Composite Materials are not always characterized by high strength fibers and high stiffness. While these properties are often desirable in advanced composites, there are various types of composites that may have different characteristics depending on the application.
- For example, some composites may prioritize other properties such as impact resistance or thermal stability over high strength and stiffness.
- Therefore, it is incorrect to generalize that all advanced composite materials are characterized by high strength fibers and high stiffness.

Corrected Statements:
1. Advanced Composite Materials are bounded by weaker matrix as compared to other materials.
2. Thermoset resins require a curing agent to produce finished part.
3. Thermoplastics can be reheated and reform into desired shape.
