(0.92m x 0.61m) flat panelCloth Type:8 layers, 1581 glass clothCloth Rotation: 0, 90°Procedure:Vacuum bagged, flat panelLaminate Resin Content: 32.3%NOTE : The Araldite ® LY 8615R / Aradur ® 8615H epoxy system will self-support during curing after 8 hours at125°F (52°C) minimum cure after infusing material. The material will cure hard after 48 hours at room temperature,however, the 125°F (52°C) minimum cure should be used for self support. Postcure can then be continuedpartially supported off the master or foam model used.Provisional product information is provided on experimental products. Samples were tested at roomtemperature unless otherwise noted. All samples were cured for 24 hours at room temperature plus six hoursat 250°F (121°C), plus six hours at 400°F (204°C). Composite samples were from a room-temperatureinfused, 14 in. x 14 in. (35.6cm x 35.6cm) flat panel. The lay-up was 8 layer, 0° rotation, TPI style #4114, Lot#7027, 5HS carbon fabric, 12 in. x 12 in. (30cm x 30cm), T-300-6K-309 yarn. Samples were cut and tested inthe warp (lengthwise) direction.Araldite ® LY8615R/Aradur ® 8615H System Page 2 of 8 October 2010
