What Is Woven Carbon Fiber Prepreg?
Woven carbon fiber prepreg is a carbon fiber fabric (plain or twill weave) pre-impregnated with a controlled epoxy resin system. JiLin Tangu woven prepreg combines the drape and visual character of woven fabric with the handling convenience of prepreg, giving excellent surface finish, balanced in-plane properties and easy lay-up. Both plain weave and twill weave styles are available across the woven prepreg range.
Product Range — Woven Prepreg Models
Standard woven prepreg models (width 1000 mm). Fabric weave style (plain / twill) is a specification option within each model rather than a separate category.

Key Properties
Balanced fabric properties. Warp and weft tensile strength typically ≥650–690 MPa with modulus ≥50 GPa (3K systems).
Premium visible-carbon surface. Twill offers the classic diagonal pattern for cosmetic parts; plain offers a tighter, flatter surface.
Controlled resin content. 42±2% typical (±0.5% available), VOC ≤1.2%.
Good drape. Woven architecture conforms well to curves and complex tooling.
Long storage life. 365 days at −18°C; 20–25 day shop life at 25°C / ≤65% RH.
Processing & Cure
Woven prepreg suits compression moulding, vacuum bag, autoclave and roll wrapping. Cure range depends on resin system: medium-temperature (120–150°C, Tg ≥110–150°C) for fast cycles, or medium-high temperature (125–175°C, Tg ≥155°C) where heat resistance matters.
Typical Applications
Automotive exterior. Body panels, hoods, spoilers and interior trim with Class-A visible-carbon finish.
Low-altitude & UAV. Airframes, propellers and structural covers.
Sports. Bicycle frames, rims, ice hockey sticks, helmets and shoe soles.
Industrial. Lightweight enclosures, rollers and decorative structural panels.
Storage & Handling
Store at −18°C or below in sealed packaging; cumulative shelf life 365 days.
Thaw sealed rolls to room temperature (≥8 h) before opening to avoid condensation.
Keep working area at 23±2°C and relative humidity ≤65%; cut prepreg laid flat, never folded.
Packaging & Delivery
Every woven carbon fiber prepreg roll is packaged in moisture-barrier PE film with desiccant and shipped in sealed, humidity-indicating cartons, protecting the prepreg from moisture and mechanical damage during storage and transport.
