Using Sheet Glass To Lay Up Fiberglass

The list below contains common designations for this material.

Using sheet glass to lay up fiberglass. The following video demonstrates the basic lay up technique to fabricate a fiberglass laminate. Too warm and it will harden too quickly. For laying up fiberglass on hard. 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.

It is imperative to work in a well ventilated area. The styrene in polyester and vinyl ester resins evaporate into the air during lay up. Instead heat up the room to accelerate the process. Fiberglass is the actual cloth or mat made up of glass fibers.

Lay mat on or in your form and spread the resin mixture over it with a disposable paint brush. 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. Glass cloth aka bi axial woven fabric aka bi axial. This will ruin your project.

As noted above the fiber does not have to be glass. However this section will cover glass fiber specifically. Too cold and fiberglass won t harden. 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. Working with fiberglass and resin can be hazardous if you are not careful. For one square foot use about 1 cup of prepared fiberglass resin. On a small lay up the fiberglass laminate which hangs over the edge of the mold can be trimmed off easily with a razor knife if you catch the trim stage of the period after the lay up has gelled but before it has hardened.

Fiberglass is a very durable material that will bond to almost any surface including plastic metal wood and styrofoam. Fiberglass in temperatures between 60 and 85 degrees f. Protect your skin and eyes by wearing gloves eye protection and clothes to cover the skin. Fiberglass resin impregnating technique.

The fiberglass resin is a thick substance that needs a catalyst to harden.
