Resin Transfer Moulding (RTM) is an efficient method of producing composite products, suited to medium volume production projects. A catalysed resin is injected into a closed mould already containing a pre-formed reinforcement. The amount of moulding material, usually a thermoset plastic is measured and inserted into the enclosed mould before the moulding can take place. The distinguishing feature of resin transfer moulding is that the reinforcement materials are placed into this cavity and the mould set is closed prior to the introduction of the matrix material.
Vacuum Assisted Resin Injection
The process includes vacuum assisted resin injection (VARI). This produces strong dense products, with dimensional accuracy and a smooth surface on both sides of the moulded component. The finished product can withstand tough environmental conditions and rough handling.
Resin Transfer Moulding Process
Resin Transfer Moulding includes numerous varieties which differ in the mechanics of how the resin is introduced to the reinforcement in the mould cavity. These variations include everything from vacuum infusion to vacuum assisted RTM. By applying pressure and vacuum the resin is forced through dry fabrics in a matched mould, a process which is performed at either ambient or elevated temperature. Once fully wetted the laminate is cured either at room temperature or in an oven. RTM combines relatively low tooling and equipment costs to produce large structural components.
Industries and Products
The process can produce composite components suitable for a vast number of different industries. RTM Products include:
Automotive Components
Aerospace Structures
Aerial Lift Buckets
Machine Covers and Housing
Marine
Wind Deflectors
Spill Containment
Medical Office Seating
Public Transportation
Agricultural & Farm
Veterinary & Animal Confinement
Industrial and Manufacturing
Corrosion Applications
Home and Recreation
Benefits and Advantages of RTM
Higher productivity and reduced labour are just some of the advantages of Resin Tranfer Moulding. Other benefits and advantages include:
Created parts are extremely durable
Accurate thickness on produced parts
Created parts will not corrode or rust
Parts are impact and chemical resistant
Parts can be fire retardant
High gloss finishes can be created on both sides of the part
Reduced waste material
Overall, Resin Transfer Moulding is an extremely efficient method of producing a wide range of composite components. It enables the production of mid-range volumes of parts at a moderate capital investment. RTM has matured to the point of being capable option for composites production and many different industries in the UK can benefit from the RTM process.
