Solvay MTM® 49-3 Epoxy Prepreg with 36% M46J-124 Carbon Fiber
Categories:	Polymer; Thermoset; Epoxy; Epoxy/Carbon Fiber Composite
Material Notes:	MTM49-3 is an 80 to 160°C (176 to 320°F) curing, toughened epoxy pregpreg resin system developed specifically for the manufacture of components. MTM49-3 pregregs exhibit excellent ambient and hot mechanical performance combined with good impact resistance after only moderate cure cycles making them ideal for use in the motorsport industry. Features & Benefits: Autoclave and press curable 60 days out life at 21°C (70°F) 12 months storage at -18°C(0°F) Versatile cure temperatures 190°C Tg Bonds directly to Nomex core in body type applications Product Variants: MTM49-3: High Tg and moderate toughness MTM49-3B: Black pigmented variant of MTM49-3 MTM49-3BB: Black pigmented variant of MTM49-3 (higher pigment loading) MTM49-3BD: Black dyed variant of MTM49-3 Property data reported for dry sample after cure cycle: 90 minutes at 135°C (275°F), 6.2 bar (90 psi). Data normalized to 55 vol% except for shear properties. Information provided by Cytec, subsequently acquired by Solvay.
