VIP Resin

**What is VIP resin for vacuum infusion process?**

It is sent into the fibers under vacuum pressure.

Dry fibers are placed inside the mold.

Vacuum is applied to the sealed vacuum bag.

VIP (Vacuum Infusion Process) resin is poured into the mold through a channel.

Vacuum infusion of VIP resin is carried out using special equipment and materials.

**Advantages of the VIP method:**

– The fiber-to-resin ratio is precisely maintained – Fibers are uniformly impregnated with VIP resin – High-strength parts – Low weight – Low viscosity – High resin flowability – Pot life of one hour

**Applications of VIP:**

– For manufacturing large parts – Parts in the marine industry

**Advantages of using VIP vacuum bag:**

– Reduces trapped air in the part – Increases fiber percentage and therefore part strength – Removes moisture, solvent, and excess vapors from the layers – Cleaner process compared to hand lay-up, with less consumable materials – A wide variety of parts with different shapes can be made using this method

**What are the advantages of using epoxy resin in the marine industry?**

Epoxy resin is a superior choice for applications requiring greater strength and impact resistance.

Compared to polyester resin, epoxy resin has higher mechanical properties, including stronger tensile strength, flexural strength, and impact resistance.

It is also more resistant to fatigue and creep, making it an excellent choice for marine structures under continuous stress.
