Product Description
>> The High Strength Carbon Fiber 3K Prepreg (spec: CWP200/42%-1000) is a versatile 3K carbon fiber prepreg, combining 3K carbon fibers (3000 filaments/tow) with 42% epoxy resin. It has a carbon fiber weight of 160–245g/m², standard width of 1000mm, 0–100m roll length, and yarn strength up to T700. Designed for sports equipment, automotive, and industrial applications, it’s used in bicycle frames, golf clubs, and automotive body kits. The 3K fibers balance strength and workability—easier to mold than 1K fibers while offering higher strength than 12K options. It supports plain or twill weaving, with customizable resin types (epoxy, phenolic, polyetheretherketone).

Is CWP200/42%-1000 suitable for mass-produced sports equipment?
Yes. Its workability and cost-effectiveness make it ideal for mass production—many leading bicycle brands use this prepreg for their mid-range to high-end frames.
Can the weave pattern of CWP200/42%-1000 be customized?
Yes. We offer plain weave (smooth, uniform) for structural parts (e.g., golf club shafts) and twill weave (decorative) for visible components (e.g., bicycle frames).
What is the difference between T300 and T700 yarn strength for this prepreg?
T300 (3000MPa tensile strength) is suitable for general sports equipment; T700 (4900MPa) is for high-performance applications (e.g., professional bicycle frames or racing car parts).

3K Fiber Towing: 3K carbon fibers (T300–T700 grade) are grouped into tows, with surface cleaning to remove dust and oil.
Weaving (Plain/Twill): Tows are woven into plain (uniform strength) or twill (flexible) patterns, with loom tension adjusted to maintain fiber alignment.
Resin Impregnation: 42% epoxy resin is applied via roller coating, with pressure control (5–10bar) to ensure full fiber coverage.
Curing Parameter Labeling: Each roll includes curing guidelines (e.g., 110°C for 30 minutes + 140°C for 90 minutes for golf clubs) to simplify processing.
Balanced Strength & Workability: 3200MPa tensile strength and flexibility for complex molds (e.g., curved bicycle seat posts), easier to handle than 1K prepregs.
Aesthetic Appeal: Twill weave creates a distinctive diagonal pattern, popular for high-end sports equipment (e.g., custom bicycle frames) and automotive interior trim.
Cost-Effective: 3K fibers are more affordable than 1K, making it a budget-friendly option for volume production (e.g., mass-market golf clubs).
Broad Resin Compatibility: Works with epoxy (standard), phenolic (fire-resistant), and polyetheretherketone (high-temperature) resins, adapting to diverse applications.

Maintenance
| Clean the surface of the carbon fiber Fabric During use, dust and stains on the surface of carbon fiber Fabric should be cleaned in time, and special cleaners should be used to avoid acidic or alkaline cleaners. |
| Prevent carbon fiber Fabric From being exposed to sunlight for a long time. Long exposure to sunlight will make the surface of carbon fiber Fabric crack and fade, affecting the beauty and service life. |
 | When storing carbon fiber Fabric Attention should be paid to avoid humidity, high temperature and other environments. When storing carbon fiber Fabric, avoid humidity, high temperature and other environments, and keep dry and ventilated. |
