What is liquid resin infusion?

What is liquid resin infusion?

Resin infusion is a composite moulding process whereby the liquid resin is drawn a stack of dry fabrics by the aid of vacuum pressure, and in doing so impregnates the laminate. We have applied resin infusion techniques for a wide variety of composite parts and tooling where it suits the process.

How long does resin infusion take?

Many resins have a pot-life of about 30 minutes, though there are certainly some (such as our System 4500 Infusion Epoxy Resin or System 4600 High Temp Infusion Epoxy Resin) that offer work times of up to 90 minutes.

What is resin transfer infusion?

Resin transfer injection or resin transfer infusion (RTI) systems are used for composite moulding processes, with steel, aluminium, or composite tools. Reinforcement is placed in the tool and resin is then injected and/or infused. Our team have strong process knowledge and a history of technical innovation.

What is infusion process?

Infusion is the process of extracting chemical compounds or flavors from plant material in a solvent such as water, oil or alcohol, by allowing the material to remain suspended in the solvent over time (a process often called steeping).

How does resin transfer molding work?

Resin transfer molding (RTM) is a method for the production of components made from fiber plastic composites. In the RTM procedure, a reaction resin is poured onto the dry, semi-finished fiber parts, and these parts are consequently immersed by applying pressure within a closed vessel.

How much vacuum is needed for resin Infusion?

You will need to vacuum bag some foam core and then several layers of fiberglass in epoxy resin. The bag will be about 25 square feet (2.5sq m.)

How much vacuum is needed for resin infusion?

What are prepregs used for?

Prepregs are typically used by experienced fabricators who are interested in minimizing the weight of their part. Typical applications include aerospace, racing, sporting goods, pressure vessels, and commercial products. Generally, prepregs are used by fabricators who have experience with hand layup and vacuum bagging.

What are the types of infusion?

Types of infusions vary and may be selected according to your particular medical condition. They are:

  • Intravenous (IV). IV therapy is the most common type and delivers medication through your veins, directly into the bloodstream.
  • Epidural.
  • Subcutaneous.
  • Intramuscular.
