Material Notes:
This material is made from woven glass cloth and high-temperature phenolic resin. It has excellent flexural, compressive and impact strengths. Physical strength, resiliency, ease and versatility of fabrication, and excellent electrical properties make phenolic laminates useful as support components in a wide range of mechanical and electrical applications. Phenolic laminates are strong, stiff, and have high impact and compressive strengths. They do not soften upon re-heating, so they are easy to saw, drill, tap, and machine with ordinary tools. Glass-based grades have the highest dimensional stability and mechanical strength, as well as low moisture absorption. However, they are not as easily machined as paper or cotton fabric laminates.
