HX50 is an epoxy resin system that can be pre-impregnated into high performance fibers such as carbon, glass and kevlar. After a suitable post-cure an end-use temperature of 180ºC (356ºF) is achieved. CHARACTERISTICS: Low initial cure temperature Unsupported post-cure Excellent drape for complex shapes High glass transition temperature 2 to 3 days work life at ambient 6 months storage life Low coefficient of thermal expansion Low volatile content The processing parameters and instructions contained in this technical datasheet are to be used in accordance with The detailed instructions provided in the document Autoclave-Cured Tools Using MULTIPREG HX SERIES available from Amber Composites. RESIN PROPERTIES Density Tg (DMTA) after 190 C (374ºF) postcure Typical C.T.E. for a carbon tool Typical C.T.E. for a glass tool 1.23 g/cm 3 (76.7lbs/ft³) at 23 C (73.4ºF) Onset: 190 C (374 F) Peak Tan δ: 2 C (428ºF) 3.1*(1.7) X10-6 / C (ºF) 12.7*(7) X10-6 / C (ºF) *CTE is dependent on construction and processing. Figures quoted are based on standard quasi-isotropic tooling laminates. INITIAL MINIMUM CURE TIMES Temperature C ( F) Time (hrs) () (113) (122) (131) 6 CURING CYCLES Initial Minimum Cure Schedules - HX50 65 Cure 6 hours at 55 C (131 F) Cure 8.5 hours at 50 C (122 F) Cure 12.5 hours at 45 C (113 F) Cure 18 hours at C ( F) Heat up rate 0.5 C/min (0.9 F/min) Total cure time (hours) Alternative cure cycles at higher temperature may be used e.g. 4hrs at C (ºF) but it should be n oted that HX50 prepreg contains a reactive resin system and care must be taken to avoid exothermic heating during the initial cure. 2 POST-CURE Post-cure schedule A: Ramp 1ºC (1.8 F) / min to ºC ( F) Dwell fo r 2 hours Ramp 1ºC (1.8 F) / min to 90ºC (194 F) Dwell fo r 1 hour Ramp 1ºC (1.8 F) / min to 1ºC (248 F) Dwell for 1 hour Ramp 1ºC (1.8 F) / min to 150ºC (302 F) Dwell for 1 hour Ramp 1ºC (1.8 F) / min to 170ºC (338 F) Dwell for 1 hour Ramp 1ºC (1.8 F) / min to 190ºC (374 F) Dwell for 6 hours Cool to 50ºC (122 F) at 2.5ºC/min (4.5ºF/min) Post-cure schedule A Heat up rate 1.0 C/min (1.8 F/min) 1 C (248 F) 90 C (194 F) 170 C (338 F) 150 C (302 F) dwell time 6 hours at 190 C (374 F) Cool down rate 2.5 C/min (4.5 F/min) dwell time 2 hours at C ( F) Total post-cure time 3 An alternative post-cure schedule may also be used as follows: Post-cure Schedule B Heat up rate C/hour (36 F/hour) dwell time 6 hours at 190 C (374 F) Cool down rate 2.5 C/min (4.5 F/min) Total post-cure time REINFORCEMENTS AVAILABLE Fiber type Weight (gsm) Weave style Molded thickness (mm) Std. resin content w/o High Strength Carbon 3k 0 2/2 Twill (surface ply) High Strength Carbon 12k 650 2/2 Twill E Glass (EC6 Yarn) H Satin (surface ply) E Glass (EC9 Yarn) H Satin E Glass (10 Tex WR) 870 2/2 Twill Other fabrics and resin weights available on request. 4 CAUTION MULTIPREG HX50 prepreg contains a reactive resin system and care must be taken to avoid exothermic heating during the initial cure. Avoid exceeding 65ºC (149ºF) initial cure. STORAGE Shelf life is 2-3 days at ambient temperature ºC (ºF) Refrigerated storage life is 6 months at 18ºC (0ºF) To avoid moisture condensation: Following removal from cold storage, allow prepreg to reach room temperature before opening the polythene bag. HANDLING SAFETY Observe established precautions for handling epoxy resins and fibrous materials. Ensure adequate ventilation, wear gloves, goggles, and protective clothing. For further information refer to Material Safety Data Sheet.
