What is Carbon Fibre Fabric?

Carbon fibre fabric is just like other fabrics except it uses carbon fibres instead of cotton, nylon, polyester, etc. The weave is coarser than fabrics used for clothing, it is more like a heavy canvas. Carbon fibre fabric needs to be laminated with a matrix (i.e. resin) to form a rigid structure.

Why are there different weaves of carbon fibre fabric?

Carbon fiber comes in different weaves optimized for different uses. For example, the standard twill weave is a good all-purpose fabric. Unidirectional fabric is good for adding strength and stiffness in one direction. Plain weave is good for delicate layups and some patterns are just designed for a unique look!

What’s the difference between carbon fibre fabric and prepreg?

Prepreg is a version of carbon fiber that already has a tacky resin impregnated into it. Both carbon fiber fabric and prepreg can be cut and formed into all sort of shapes. Unlike carbon fiber fabric which can be made at room temperature, prepreg requires elevated temperatures and pressure to cure properly.

Description

Spabond™ 440 is a highly versatile toughened, high performance adhesive system that is suitable for bonding a wide range of materials. Spabond™ 440 has been developed from the proven performance of Spabond™ 340, whilst sharing the same hardener components as Spabond™ 435 and 445 to deliver a complete adhesive system.

Spabond™440 can be applied in thicknesses of up to 20mm at 20°C on vertical surfaces, without the risk of drainage whilst retaining excellent flow characteristics to achieve thinner bond lines over large areas. Available with a choice of two hardeners, improved cure progression chemistry eliminates the need for an extra-slow hardener.

The product has a 3:1 mix ratio by volume. To aid mixing, the hardener components are pigmented to give visual indication of mix quality.

Spabond™ 440 is available in cartridges and straight-sided pails & drums for machine mixing/dispense.
