In this tutorial series we will learn how to make simple fiberglass parts.
Introduction
Fiberglass is a very versatile material. Can replace steel, iron, aluminum and plastic parts in almost all applications.
It doesn't rust or rot in water.
It is much stronger and lighter than similar size steel and aluminum parts.
Can be molded to form channels as well as pipes, tubes, sheets etc.
Fiberglass parts can be made without any specific molding tools and equipments.
Fiberglass parts can be very easily made at home for any DIY projects or any small workshop.
Using this tutorial you can make larger and complex parts and molds from fiberglass.
In this tutorial we will make 2 parts one with first layer of gelcoat and one without.
The application of gelcoat will provide a good and glossy surface finish.
Without a layer of gelcoat there will be some imperfections and air bubbles on the surface of the part.
Materials required:
The mold can be made from most locally available materials like steel, aluminum, wood, MDF, plastic, mirror or glass etc.
But for best results we recommend using sheet of glass as mold surface.
In this tutorial we are using a sheet of glass for as a mold.
The part will have the surface finish of the mold. So incase the mold surface is glossy then the part will be glossy too.
Incase the surface finish of the mold is matt finished then the part will have similar finish as well.
Today we will make 2 sheets of fiberglass one with thickness of approximately 1mm and another with thickness of approximately 3mm.
Each sheet will be 6in x 6in
Using this method we can make sheets of fiberglass composite from as thin as 0.5mm to 25mm thick.
Step I: Mold preparation
Clean the mold ie. the sheet of glass using a chemical mold cleaner or soapy water and a micro fiber cloth
Step II: Application of release agent
Once dried off using a wax applicator sponge apply it to the mold surface.
Using a clean microfiber cloth buff off the dried wax from the surface of the mold.
Repeat this step 3 more times then let it dry for atleast 30mins.
Take a small quantity of PVA release agent in a cup.
