Mitsuya uses Victrex Aptiv to make 40um prepreg

A Victrex product story
Edited by the Engineeringtalk editorial team Mar 11, 2009

Mitsuya, a Japanese developer of carbon-fibre composite material, has used Victrex Aptiv film as the matrix polymer to develop a 40um prepreg sheet.

This sheet has enabled lighter weight and higher performance than traditional carbon-fibre composite materials.

Carbon fibres are manufactured into tows consisting of several thousand strips of carbon fibre.

Mitsuya uses a technology that opens the tows and continuously spreads them widely, thinly and evenly before processing them into a sheet.

Fibres that are spread out evenly simplify polymer impregnation.

Thinner prepregs have excellent evenness/balance when used in layer processes, allowing manufacturers of moulded products to accommodate a range of thicknesses.

The new prepreg is a uni-directional (UD) sheet that combines Victrex Peek polymer-based Aptiv film and strips of carbon fibre lined up in one direction.

The prepreg forms uni-directional layers and multiaxial layered prepregs moulded through heat and pressure treatment and combined in multiple directions.

Because of their high heat resistance, material strength and lightweight characteristics, prepregs are used in athletic products and Formula One cars.

They are gaining the attention of automobile and aircraft manufacturers seeking to improve fuel efficiency and operational costs through weight reduction.

Multiaxial layered prepregs, for example, are ideal for aircraft structural parts that require material strength to withstand impact from multiple directions.
