Aerospace Grade Lightweight 1K Carbon Fiber Prepreg

>> The Aerospace Grade Lightweight 1K Carbon Fiber Prepreg (spec: CWP100/42%-1000) is a premium 1K carbon fiber prepreg engineered for aerospace and high-end applications. It features a carbon fiber weight of 90–140g/m², 42% resin content (epoxy), standard width of 1000mm, and 0–100m roll length. The 1K carbon fibers (1000 filaments/tow) deliver exceptional smoothness and precision, making it ideal for aerospace components (e.g., aircraft wing skins), satellite antennas, and medical devices (e.g., surgical tools). It supports plain or twill weaving, with yarn strength up to T300—ensuring reliability in mission-critical applications.

FAQ

Why use 1K fibers instead of 3K or 12K for aerospace applications?

1K fibers are finer, creating a smoother surface (reducing drag) and allowing more precise molding of small, complex parts (e.g., satellite connectors) where 3K/12K fibers would be too thick.

What weaving options are available for CWP100/42%-1000?

Plain weave (uniform strength, smooth surface) for wing skins and twill weave (better flexibility, distinct texture) for curved components like aircraft engine nacelles.

What is the maximum operating temperature of CWP100/42%-1000?

With epoxy resin, it operates up to 150°C; with bismaleimide resin, it withstands up to 250°C—suitable for most aerospace and medical applications.

Suitable Production Process

1K Fiber Selection: Ultra-fine 1K carbon fibers (T300 grade) are screened for uniform diameter (5–7μm) and tensile strength (>3500MPa).

Weaving (Plain/Twill): Fibers are woven into plain or twill patterns, with loom speed reduced to 100 picks/min to avoid fiber breakage.

Epoxy Impregnation: 42% epoxy resin is impregnated into the fabric using vacuum infusion, ensuring every filament is coated.

Low-Temp Curing Prep: The prepreg is cooled to 10–15°C to slow resin curing, with release film applied to protect the surface during storage.

Characteristics

Aerospace-Grade Precision: 1K fibers create a smooth surface (Ra <0.5μm), ideal for aircraft wing skins (reducing aerodynamic drag).

High Strength-to-Weight Ratio: 3500MPa tensile strength at 1.7g/cm³ density, making it 6x stronger than aluminum per unit weight.

Biocompatibility: Epoxy resin meets ISO 10993 standards, suitable for medical surgical tools (non-toxic and non-irritating).

Dimensional Stability: Low coefficient of thermal expansion (1.5×10⁻⁶/°C), ensuring satellite antennas maintain shape in space temperature fluctuations.

	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.

In summary, carbon fiber Fabric has a long service life, but long-term use also needs to pay attention to some matters. During use, attention should be paid to prevent damage to the surface of the carbon fiber Fabric, to avoid environmental effects such as high temperature and high humidity, and to check the use regularly. 

In terms of maintenance,attention should be paid to cleaning the surface of the carbon fiber Fabric, avoiding long-term exposure to the sun, and properly storing the carbon fiber Fabric.
