Glass Fiber and Filled Resin Under the Microscope

Glass Fiber and Filled Resin

This is a glass fiber from the core panel of an office partition. The core panel has a high resin content and the resin often has a high mineral filler content.

A common structure for a cubicle divider consists of a metal frame supporting a resin stiffened glass fiber panel. The glass fiber panel is then covered with a thin loose glass fiber blanket and an outer layer of cloth. Glass fiber from the cubicle divider is heavily coated with heavily filled yellow or orange phenolic resin. The deterioration of the glass fiber panel is typically due to the panel's use as a pincushion or to other forms of mechanical damage.
