WET LAYUP METHODS

When applying fiberglass cloth or carbon fiber with laminating resins via wet layup, several techniques can be used depending upon the weight of your fabric. Fiberglass or carbon parts can also be made through the vacuum bagging process. We’ll describe best practices for applying fiberglass and carbon fiber based on your fabric weight.

Lightweight Fabrics

Lightweight (4 – 6 oz.) fiberglass cloth, popular in surfboard laminations, is easy to wet out from the top. It will become transparent when fully wet out with Entropy Resins epoxy.

Heavyweight Fabrics

Heavier weight fabrics (12 oz or more) are more difficult to wet out from one side. The best practice for wet layup of heavyweight fabrics is to apply epoxy to the surface first to ensure the fabric wets out on both sides.

DRY LAYUP METHODs

Vacuum Bagging

The vacuum bagging process can follow either the wet or dry method of applying fiberglass, depending on the fabric weight. Vacuum bagging consolidates the part while the epoxy is curing and achieves a higher fiber weight ratio and therefore a stronger part.
