EU Regulation No 267/2012

Resin impregnated fibre prepregs and metal coated fibre preforms, for the goods specified in 6.A.1., made either with organic matrix or metal matrix utilising fibrous or filamentary reinforcements having a specific tensile strength greater than 7,62 × 104 m and a specific modulus greater than 3,18 × 106 m.Note:The only resin impregnated fibre prepregs specified in 6.C.1. are those using resins with a glass transition temperature (Tg), after cure, exceeding 145 °C as determined by ASTM D4065 or national equivalents.Technical Notes:1.In Item 6.C.1. ‘specific tensile strength’ is the ultimate tensile strength in N/m2divided by the specific weight in N/m3, measured at a temperature of (296 ± 2)K ((23 ± 2)°C) and a relative humidity of (50 ± 5)%.2.In Item 6.C.1. ‘specific modulus’ is the Young's modulus in N/m2divided by the specific weight in N/m3, measured at a temperature of (296 ± 2)K ((23 ± 2)°C) and a relative humidity of (50 ± 5)%.
