Process to be used for Aerobody Production: Vacuum Infusion Process

This process requires a lot of preparation and preplanning in order to be done properly.  The initial selection of materials to be used for the process is very important including molds, vacuum lines and the actual material to be infused with resin.  Some of the important aspects of the process that have to be accounted for are the amount of time required for the infusion to be completed in and the speed at which the resin and hardener will spread throughout the material.  This leads to the consideration of the viscosity of the resin, the permeability of the material and the additional flow media within the material to aid in the infusion process.

The viscosity of the resin is important, as it determines how much times is required for the infusion to be completed and how well and even it spreads throughout the material.  The recommended viscosity is at less than 400 centipoise, however higher viscosities can be used, but curing time must be a lot longer to allow for the spreading to occur.

The permeability of the material is also important, due to it also determining the efficiency at which the resin and hardener spreads through the material.  The currently selected type of material will be sufficient for this, as the weaved fibres allow for easy spreading of the resin.  However looser weaves are recommended for easier spreading.

The flow media to be used has to also be considered.  Even though infusion can be done without any flow media throughout the material, it will take much more time to properly spread the resin and hardener throughout the mold.

Fibreglass types:

Fibreglass is a type of composite material that can be used in order to form parts.  Even though fibreglass is generally made of the one material, glass, there are many specifications and types that change its material properties and the process by which a part can be created.

Fibreglass is designated by 3 / 4 letters.  The 1st letter defines the type of glass within the fibreglass, where E is Electrical and S is high-Strength.
