1. If the processing requires to force out any air bubbles from the molten mass engineers can apply pressure. 2. The main target of specialists is to produce composite materials with unique properties. That’s why they make different materials work together. 3. The matrix material for specific purposes must be softened and only then it can be shaped with tools. 4. If we want to repair such a composite it can be softened by suitable solvents. 5. The properties of composites are to meet specific requirements, so technologists try to tailor some of them. 6. One of the numerous tasks is to create the composite sheet which is very strong in one direction. Specialists manage it by aligning the fibres in a certain direction. 7. If the composite is to be exposed to high temperatures ceramics is often used for this purpose. 8. Technologists are to choose an appropriate combination of reinforcement and matrix material if they need that material would fit exactly the requirements for a particular purpose.
