We review fiber spreading, impregnation and forming conditions together with quality variation.
Prepreg
Prepreg
- Fiber spreading and web-width stability
- Resin film weight, temperature, pressure and line speed
- Resin content, tack, drape and void variation
- B-stage control of thermoset systems
Pultrusion
Pultrusion
- Fiber alignment, tension and resin wet-out
- Die temperature, pull speed and cure state
- Cross-section quality, dimensions and surface defects
Deliverables
- 01Process diagnosis report and revised conditions
- 02Test plan and quality control items
