Description

Airtech TMFP & TMGP prepregs are proven tooling materials on long running programs. The initial 121°C cure with an optional 93°C cure offer a medium temperature cure, with long term high temperature performance.

TMFP 3100 is a light weight fibreglass/epoxy tooling prepreg used on the first and last plies.

TMFP 3200 is a heavy weight fibreglass/epoxy tooling prepreg used to produce moulds with a medium temperature initial cure and high temperature capabilities after post cure.

TMGP 4000 is a light weight carbon/epoxy tooling prepreg used to produce moulds with medium temperature initial cure and high temperature capabilities after post cure. TMGP 4000 can also be used to reinforce our Airpad rubber tooling, see Airpad data sheet in the Rubber Section.

TMGP 4100 is a medium weight carbon/epoxy tooling prepreg that can be used to produce moulds with a medium temperature initial cure and high temperature capabilities after post cure. This product is also ideal for Airpad reinforcement.

TMGP 4200 is a heavy weight carbon/epoxy tooling prepreg that can be used to produce moulds with a medium temperature initial cure and high temperature capabilities after post cure.

Benefits

• Toolmaster® composite moulds match tool and part CTE improving part accuracy.
• Lower thermal mass than metallic tooling for shorter heat up time.
• Can also be used for reinforcing Airpad Rubber tooling.

Cure Instructions

Notes

• Temperature measurements should be obtained with thermocouples, properly placed for accurate
temperature readings. Program controller should follow lagging thermocouple for cure and post cure.
• Do not apply solvent to the mould surface prior to post cure.
• Contact Airtech for our Guide to Toolmaster® Tooling for complete information.
• To avoid condensation, allow prepreg from freezer to warm to room temperature before using.
