Manufacturing processes
Reinforcing glass fibers

Glass fibers can be manufactured using so-called direct-melt processes (fiberizing molten glass continuously in a furnace) or indirect-melt processes (fiberizing glass by remelting glass cullet in the form of berlingots or beads). We will limit ourselves to describing the most common process, since it optimizes both throughput (quantity of glass fiberized per day) and production yields, i.e. the direct melting process.

There are several stages:

• batch preparation ;

• batch melting to obtain molten glass;

• glass fiberizing and sizing ;

• fiber winding ;

• finishing.
