Resin Infusion Application
Infusion production method recommended for applications like production of marine vehicles and wind turbine blades. It is also useful for the automotive industry in production of low volume parts. Primary purpose is cutting down VOC emissions with high glass fiber ratios of up to 70% and homogeneous distribution of resin through out the part body without air entrapment. Composite parts produced with the infusion method have exceptional mechanical strength.
Resin Infusion Products
Both Polives 701-TA skincoat and Polives 702 Infusion type vinyl ester resins are recommended for infusion.
Silicone Membrane System
L–RTM and Infusion resins can be used with vacuum bags and/or reusable silicone membranes.
RTM - Resin Transfer Molding
Composite production with RTM method has the following advantages: good surface appearance on both sides, low workmanship, better dimensional stability, lower styrene emission, high productivity. Because of these properties, it is an ideal method for the production of vehicle parts with or without gelcoat. RTM production steps:
① Apply mold release agent on mold surface
② Apply a gelcoat film of 500-800 microns
③ Lay down reinforcement material on cured (but tacky) gelcoat
④ Close upper mold
⑤ Apply vacuum to seal mold
⑥ Apply vacuum inside the mold if needed
⑦ Check peroxide ratio and equipment pressure
⑧ Inject resin into the mold
⑨ Stop injecting when resin capacity is reached
⑩ Demold the composite part after resin finishes curing
RTM and Light RTM production provides a faster composite part production rate with shorter cycle time compared to hand lay-up or spray-up production methods. Incorporation of heating-cooling systems to molds will also speed up production rates.
