MIL-HDBK-17-2F Volume 2,Chapter 4 Carbon Fiber Composites CHAPTER 4 CARBON FIBER COMPOSITES 4.1 INTRODUCTION 4.2 CARBON-EPOXY COMPOSITES 4.2.1 T-500 12k/976 unidirectional tape Material Description: Material: T-50012k/976 Form: Unidirectional tape,fiber areal weight of 142 g/m,typical cured resin content of 28-34%, typical cured ply thickness of 0.0053 inches. Processing: Autoclave cure;240F,85 psi,1 hour;350F,100 psi for 2 hours. General Supplier Information: Fiber: T-500 fibers are continuous carbon filaments made from PAN precursor,surface treated to improve handling characteristics and structural properties.Filament count is 12,000 filaments/tow.Typical tensile modulus is 35.5 x 10 psi.Typical tensile strength is 575.000psi. Matrix: 976 is a high flow,modified epoxy resin that meets the NASA outgassing requirements. 10 days out-time at 72F. Maximum Short Term Service Temperature: 350°F(dry),250°F(wet) Typical applications:General purpose commercial and military structural applications,good hot/wet properties. 4-1MIL-HDBK-17-2F Volume 2, Chapter 4 Carbon Fiber Composites 4-1 CHAPTER 4 CARBON FIBER COMPOSITES 4.1 INTRODUCTION 4.2 CARBON - EPOXY COMPOSITES 4.2.1 T-500 12k/976 unidirectional tape Material Description: Material: T-500 12k/976 Form: Unidirectional tape, fiber areal weight of 142 g/m2 , typical cured resin content of 28-34%, typical cured ply thickness of 0.0053 inches.
