T700 Carbon Fiber: Resolving S and G Suffixes

Toray's data-sheet index lists T700S and T700G separately. A short T700 description omits part of the product identity. Material reference.

Resolving S and G Suffixes

Before comparing a supplier's fabric or prepreg, resolve the exact fibre and the resin system. Do not merge values from different T700 products or assume that a tow specification represents the properties of a cured woven plate.

Manufacturing and acceptance checks

Request the full fibre code, tow, sizing, fabric or tape construction and resin. Define layup, cure and loading direction for the component. Compare test evidence from the proposed laminate, and approve any change from T300 or another T700 variant as a controlled material-system change.

Reference and scope

Toray: fibre and prepreg data sheets, including product suffixes provides material or specification background. The checks above are purchasing guidance; final acceptance values must come from the agreed grade, product specification and condition.
