Load direction, geometry, environment, process and acceptance question.
Carbon reinforcement and prepreg systems
Toray Composite Materials Defined from Fiber to Laminate
Connect fiber grade, tow size, sizing, orientation, areal weight, resin content, prepreg storage, out-time, layup and cure cycle before mechanical evidence is compared.
Start with the process and load path
Architecture, resin and manufacturing route determine the useful sample. Fiber tensile data alone cannot predict laminate or component behavior.
| Format | Control fields | Process question | Evidence stage |
|---|---|---|---|
| Carbon tow | Fiber grade, tow size, sizing and package | Spreading, impregnation or textile conversion | Incoming identity and conversion trial |
| Woven reinforcement | Weave, crimp, areal weight, width and orientation | Drape, cut, placement and resin flow | Process panel and directional coupon |
| Unidirectional tape | Fiber alignment, resin content, width and backing | Placement, gaps, overlaps and compaction | Layup trial and laminate coupon |
| Prepreg | Resin, storage, thaw, out-time, tack and cure | Layup window and thermal history | Cured panel, coupon and lot release |
