Technical Details & Test Data
- Process Information
- The following are general recommendations for successful processing. Adjustments may be required to achieve optimum results in your specific manufacturing environment.
Mil Spec Phenolic Resin(Meets MIL-R-9299C, Grade B) Resin PSR133 Shelf Life 3 Weeks < RT (77oF, 25oC)
6 Months < 40oF (5oC)
12 Months < 0oF (-18oC)
We recommend that our PSR133 be pressed in the following steps for fixed platen pressing using stops:
- Set initial platen temperature to 270-280oF.
- Lay up the material with adequate release film and an edge constraint/containment system (aluminum or steel shims). The shims are necessary to avoid resin overflow or “foaming” around the perimeter. Panel should be pressed to thickness required by MIL-DTL-62474F.
- Place prepreg into press and close to establish contact pressure (10-40 psi).
- Hold temperature until panel core reaches 260-270oF.
- Increase pressure on prepreg to consolidate to required thickness and hold this pressure.
- Increase platen temperature at a rate of 4-7oF/min until platens reach 340-350oF set point.
- Hold at temperature and pressure for 30 minutes until core of panel reaches 335-345oF.
- Reduce platen temperature until core of panel is below 180oF while maintaining pressure.
- Open press and remove completed panel.
