This specification covers one type of organic fiber in the form of roving. The product shall be formed as four ends of 1140 denier yarn (AMS 3901/3) collected into an approximately parallel arrangement without twist.
Organic 4560 denier (5070 d tex) roving with 500 ksi (3447 MPa) or 21.0 g/d minimum tensile strength and 17.5 Msi (121 GPa) or 815 g/d minimum tensile modulus for use in filament winding requiring high tensile strength and high modulus of elasticity in tension.
