However this section will cover glass fiber specifically.
Using sheet glass to lay up fiberglass.
Protect your skin and eyes by wearing gloves eye protection and clothes to cover the skin.
The styrene in polyester and vinyl ester resins evaporate into the air during lay up.
Fiberglass resin impregnating technique.
It is imperative to work in a well ventilated area.
For laying up fiberglass on hard.
Too warm and it will harden too quickly.
Lay one of the sheets of fiberglass on the surface.
Working with fiberglass and resin can be hazardous if you are not careful.
Fiberglass in temperatures between 60 and 85 degrees f.
The mat or cloth will seem to melt into the resin as you spread it and you can use the brush and additional coats of resin to build up the layer of fiberglass to a thickness of up to 1 4 inch 0 6 cm.
The following video demonstrates the basic lay up technique to fabricate a fiberglass laminate.
Glass cloth aka bi axial woven fabric aka bi axial.
The fabric to resin ratio was carefully calculated to yield a maximum of 35 resin content and process demonstrate how to produce low porosity or entrapped air bubbles large voids and microscopic porosity within the laminate.
The list below contains common designations for this material.
As noted above the fiber does not have to be glass.
For one square foot use about 1 cup of prepared fiberglass resin.
On a larger lay up it can be trimmed with a saw or diamond blade.
Fiberglass consists of fiberglass mat that is saturated with a fiberglass resin.
Lay mat on or in your form and spread the resin mixture over it with a disposable paint brush.
Too cold and fiberglass won t harden.
Instead heat up the room to accelerate the process.
This will ruin your project.
Fiberglass is the actual cloth or mat made up of glass fibers.
The fiberglass resin is a thick substance that needs a catalyst to harden.
Work in a well ventilated area.
