2511 Prepreg SystemData Sheet
PRODUCT NOTESThis semi-toughened epoxy prepreg system was specifically formulated for better oven cure processing than the 2510
general aviation (AGATE) prepreg system. 2511 provides excellent all-around structural properties with a high wetand dry TG while offering a flexible cure temperature (250°F to 350°F, 121°C to 177°C) with a very low void content. This
prepreg system also can be used in industrial and recreational applications.
Industry Material Specification
Material procurable to CMA specification
TCPF-T-2511 or Aerospace Material Specification(AMS) 3962.

Industry Database
Select products listed in CMH-17 Vol 2. Contact usfor more information.

Easy Layup
Product allows complex part layup with minimal
cuts or ridge lines. It maintains a comparable class
A finish through post-cure, minimizing sanding andfinishing times.

Flexible Cure Methods
Curing methods include autoclave or oven cure.
Product can be cured with or without using a dwell.

Readily Available
AMS products, marked with this icon, are kept instock and ready to ship.

High Heat Tolerance
High Tg is suitable for structures exposed toelevated service temperatures.

AVAILABLE PRODUCT FORMATS

2511 resin is available with numerous types of unidirectional carbon fibers and woven and glass fabrics with Fiber Areal Weight(FAW) ranging from 70 g/m2 to 300 g/m2 and Resin Content, (RC%) by weight percent, ranging from 24% to 44%. The tablebelow lists commonly available product formats. Unidirectional products can be slit to widths between 1/8” and 60”, and fabricproducts to widths above 6”. Common product formats include: 1/4”, 1/2”, 1”, and 1.5” AFP spools (UD only); 6”, 500mm, 9”,
and 12” ATL rolls; and 24” to full width rolls for hand layup.

BAGGING PROCEDURE

Notes:
1. Debulk every four plies, or as needed, when laying up material.
2. It is recommended that panels have a pre-cure vacuum hold depending on size: for small panels 1 hour, for medium
sized panels (>1ft2) for 3 hours, and for complex layups (ply drops, >2ft2) for 16+ hours.
3. The vacuum should be checked for leaks before beginning the cure cycle. The leak rate shall be less than 2.0 inches ofHg (7 kPa) over 5 minutes.
Please refer to the SDS for handling and disposal.

RECOMMENDED OVEN CURE CYCLE
1. Apply full vacuum* to the part. Higher vacuum levels will yield better results.
2. Maintaining vacuum for at least three hours prior to beginning cure cycle is recommended for optimal part quality. This
promotes the extraction of trapped air and gases, producing a lower void content.
3. Ramp to 270 ± 10°F at 1-5°F/min (132 ± 5°C at 0.6-2.8°C/min) and hold for 120 minutes.
4. Cool temperature down to 130°F at max rate of 5°F/min (54°C at 2.8°C/min).
* Required vacuum level varies depending on elevation. 28” Hg (95 kPa) is the recommended minimum at sea level under average conditions.
