21. Conclusions
High performance mechanical properties can be achieved using a combination of Recycled semi-preg, granulate, laminates, or UD tape.
Material combination has proven to create a new category of material that is capable of changing the selection of materials that designers currently have available.
Excellent machinability and ability to be molded into thick laminates or solid shapes creating a new category of material.
Combination of unique fiber placement and excellent machinability make it a great choice for high temperature and high pressure component applications.
