HexMC®-i Moulding Concept Carbon Epoxy HexMC®-i / C / 2000 / M77 Provisional Datasheet Description HexMC®-i is a high performance carbon moulding composite, specifically designed for compression moulding. The epoxy matrix and high carbon fibre volume content enable components to be moulded for a wide range of applications. Overall features n n n n n n Competitive alternative to lightweight metal alloys (Al, Mg, Ti). Designed for compression moulding. Rapid processing cycles. Complex shapes. Moulded-in inserts. No material waste. Form : Roll Roll width : 460mm Shelf life at -18°C : 18 months Shelf life at RT 23°C : 6 weeks Material density : 1.55 g/cm3 Typical cure temperature : 150ºC Resin ID Areal weight (g/cm2) Carbon Areal weight : 2000 g/m2 Fibre length : 50 mm Fibre : HS Carbon Nominal fibre volume : 57% Typical cure time: 3 minutes Remove HexMC®-i from freezer. Allow it to warm up to room temperature for easier handling. Clean the mould with appropriate solvent to remove all impurities. Apply external release agent. Heat the mould to 150°C. HexMC®-i curing time varies according to part thickness. Set press pressure to 80 bars. Modify pressure up or down according to the complexity of the part. Remove the protective film. Determine the part weight. Cut HexMC®-i to size accordingly. Load the product into the mould. It is recommended that approximately 80% of the mould area is covered. Close the mould and apply pressure. Hold the pressure for the appropriate cure time. After curing, open the hot mould and release the part. A mould equipped with ejector pins is recommended to help dem

HexMC®-i / C / 2000 / M77 Note: HexMC®-i flow is greatly improved with temperature advancement, typically by heating in an oven. Heat can be applied to HexMC®-i as it comes off the roll, after patterns are cut, or as preforms are made. The material is highly formable right after staging but becomes very stiff after cooling. Recommended staging and the complementary cure cycle for a 4mm thick panel is as follows: Typical cure cycle: 3 minutes at 150°C (can be adapted accordingly to part design). Mechanical properties Data is the result of several tests on cured laminates. Some of the values achieved...
