Frequently Asked Questions

01

Is this a suitable prepreg for premium visible carbon fibre parts?

MTC575 is designed specifically for high-end cosmetic carbon fibre components. It delivers excellent clarity, depth and surface quality, making it ideal for luxury automotive, motorsport and other applications where appearance is a key part of the finished product. 

02

How do you get the best surface finish on carbon fibre parts?

Using a prepreg made specifically for the outer surface can make a big difference. MTC575 is designed as a premium surface ply and works best with MTC275 underneath for a more consistent, high-quality finish. 

03

What prepreg is suitable for luxury automotive carbon fibre?

MTC575 is aimed at premium visual applications, including supercars and hypercars. Its clear resin and carefully selected reinforcements help produce the deep, refined carbon finish expected on high-end visible components. 

04

Can cosmetic carbon fibre prepreg cope with heat?

Yes. MTC575 is designed for visual parts that also need reliable heat resistance, with a glass transition temperature above 120°C (248°F). This makes it suitable for many demanding automotive and motorsport applications. 

05

What is the difference between MTC575 and MTC275?

MTC575 is the premium surface material, designed to give the best possible visual finish. MTC275 is commonly used behind it as the backing layer, helping create a more consistent and reliable finished part.
