Fiberglass
has the same basic substance used in window and glassware. Molten glass
is extruded through ultra fine openings measured in microns, resulting
in thread-like formations which can be woven together to form a rough
cloth or patch. Different resins can then be added to this material,
allowing it to be formed and pressed into molds. The result is a
heat-resistant, lightweight panel ideal for electronic circuit boards or
support structures for complex machinery.
Fiberglass
mixed with resins can also be used to form the shell of racing cars or
other custom designs. Repairs can be made with a commercial product
called Bondo, which is essentially a fiberglass tape mixed with a
quick-curing resin. When this material is used for car body work, it can
be sanded smooth and painted to match the rest of the vehicle. It may
not have the inherent tensile strength of steel, but a skilled auto body
repairman can often match the section repaired with fiberglass and
resin seamlessly with the rest of the car.
Because
the main ingredient is real glass, microscopic bits of glass powder or
shards are often formed. Those installing it insulation should always
wear gloves, safety glasses and masks. The glass shards and powder can
remain on the skin even after several washings. These particles can be
very irritating to the lungs and hands and extremely damaging to the
eyes. A protective hand cream barrier may help prevent some fiberglass
powder buildup.
If
you work around the compressed form of fiberglass (i.e. electronic
boards), compressed air may be the best way to remove tenacious residue.
Avoid touching eyes or other sensitive areas while working with this
material in any form. If the powder does enter the eyes, use plenty of
clean water or approved eye wash and visit an eye doctor for emergency
examination.
