Context: The reinforcement type defines two major classes of materials - woven and non-woven. Woven reinforcements are cheaper, but the high dielectric constant of glass may not be favorable for many higher-frequency applications. The spatially nonhomogeneous structure also introduces local variations in electrical parameters, due to different resin/glass ratio at different areas of the weave pattern. Nonwoven reinforcements, or materials with low or no reinforcement, are more expensive but more suitable for some RF/analog applications.

Question: Along with the non-woven class, what makes up the reinforcement type materials?
Answer: woven

Question: Which is the more expensive reinforcement type?

Question: What type of structure do woven reinforcements have that cause them to have variation in their electrical parameters?
Answer: spatially nonhomogeneous

Question: Which ratio varies because of the structure of woven reinforcements?
Answer: resin/glass

Question: For what kind of applications are non-woven reinforcement materials better than woven ones?
