Carbon Fiber Fabric 4 Harness Satin 3k 5.5oz/186gsm Toray T300
Description
Carbon Fiber Fabric — 4-Harness Satin (4HS) · 3k Toray® T300 · 5.5oz (≈186gsm)
This premium carbon cloth uses Toray® T300 3k PAN-based fiber in a classic 4-Harness Satin (4HS) architecture that delivers excellent drape and a refined surface. At 5.5 oz (≈186 gsm) and ~0.009" nominal thickness, it conforms readily to tight radii and compound curves, making it a versatile choice for both cosmetic skins and structural layups. Available in popular widths (see options), and offered with/without tracer identification yarns depending on variant.
Why choose this 4HS fabric
- Outstanding drape: 4HS satin slides over itself for clean layups on complex geometry.
- High-quality fiber: Toray® T300 3k PAN carbon provides reliable strength and a crisp cosmetic appearance.
- Beautiful finish: Satin face produces a smooth, premium surface ideal for clear-coat cosmetics.
- Easy laminate build: Medium-light areal weight stacks efficiently for skins, sandwiches, and selective reinforcement.
- Flexible configurations: Offered in multiple widths with optional tracer yarns on select SKUs.
Typical applications
Cosmetic panels and hoods, motorsports and marine components, UAV/RC airframes, sporting goods, industrial covers and enclosures, and general composite reinforcement where drape and finish matter.
