TC380 Epoxy Resin System PRODUCT TYPE 356 F (180 C) Cure Toughened Epoxy Resin System TYPICAL APPLICATIONS Aircraft Structures Thick parts cured under low pressure Honeycomb stiffened parts Automated and hand lay-up fabrication processes DUAL CURE OPTIONS: VACUUM BAG ONLY Cure A - 1 F (0.6 C) per minute to 225 F (107 C), hold for one hour, then 1 F (0.6 C) per minute to 356 F (180 C), hold two hours. Cool to below 120 F (49 C) at 5 F (3 C) per minute or less, release vacuum. Cure B - 1 F (0.6 C) per minute to 225 F (107 C), hold for one hour, then 1 F (0.6 C) per minute to 275 F (135 C), hold three hours. Cool to below 120 F (49 C) at 5 F (3 C) per minute or less, release vacuum. Demold and post cure free standing at 356 F (180 C) for two hours. ALTERNATE AUTOCLAVE CURE 1-2 F/min. to 225 F (107 C), hold for one hour under full vacuum, then, apply 45 psi, release vacuum after 20 psi. 1-2 F/min. to 356 F (180 C) hold for two hours. Cool 5 F/min. to 120 F. PRODUCT DESCRIPTION TenCate TC380 sets a new benchmark for toughened epoxy prepreg systems. TC380 is extremely tough with an excellent balance of OHC, OHT, CAI, and G IC /G IIC properties. It features low moisture absorption with outstanding hot/wet mechanical properties to 250 F (121 C). TC380 is optimized for out of autoclave/ vacuum bag only cures, facilitating construction of large or complex composite parts and assemblies. Unlike some other highly toughened systems, there is no need to sequence the prepreg front and back face, assuring robustness and simplifying lay-up. TC380 tack and out life are 21 and 30 days, respectively. PRODUCT BENEFITS/FEATURES Outstanding toughness, open hole, and compression after impact properties Excellent hot/wet strength retention Robust processing and low voids under vacuum only cure pressure Long outtime and tack life for extended shop floor handling Tack and handling qualities are well-suited to both automated and hand lay-up methods Can be processed with initial cure at 275 F (135 C), followed by free standing post cure at 356 F (180 C), increasing process flexibility and tool material options Exceptional fracture toughness NEAT RESIN PHYSICAL PROPERTIES Density g/cc Dry Tg (DMA) with 356 F (180 C) cure F (201 C) Total Mass Loss (TML) % Collected Volatile Condensable Material (CVCM) % Water Vaper Recovered (WVR) % TC PLY WING SPAR TenCate measured void content in various locations on a 91-ply wing spar, showing a high degree of consolidation under OOA/VBO processing. Part Shown: ~30 x ~11 x 0.75 (thickest area) Excellent strength retention from RTD to ETW SHELF LIFE Tack Life: 21 days at 75 F (24 C) Out Life: 30 days at 75 F (24 C) Frozen Storage Life: 12 months at 0 F (-18 C) Tack life is the time during which the prepreg retains enough tack, drape and handling for easy component lay-up. Out life is the maximum time allowed at room temperature before cure. Page 1 of 9 UNITAPE LAMINATE PROPERTIES Unidirectional laminate data used IM7-GP 12K Carbon Fiber, 150 gsm FAW, 34% RC.

TIME *Followed by 356 F/180 C free-standing post cure BAGGING FOR CURE TCAC recommends that bagging of epoxy composite parts for cure should be performed as follows. 1. Release the tool surface. 2. Layup part using standard debulking procedures. 3. Dam the edges of the part for cure. 4. Place one ply of porous Teflon or perforated Teflon onto the bag surface of the part. 5. Place bleeder layers over porous Teflon material and trim to the part periphery. 6. Place a non-porous layer of Teflon over the part. 7. Utilize a breather cloth to assure a clear path for vacuum. 8. Install vacuum bag on the tool for cure. 9. Follow the provided TCAC cure cycle for the particular resin system. Page 6 of 9 COMPOSITE LAMINATE STACKING SEQUENCE LIST OF MATERIALS 1.
