Prepreg Carbon Fiber Sheets 1mm

Fibermak Composites' High Strength Carbon Fibre Sheet is manufactured using 100% carbon fibre reinforcement and epoxy resin matrix, cured under pressure at elevated temperature to produce a carbon fibre sheet with engineering-grade mechanical properties and a class-A surface finish.

The 'A-side' of the sheet has the classic 2/2 twill, 3k woven carbon fibre appearance with a pin-hole free high gloss finish. The reverse of the sheet features an even textured 'peel ply' finish suitable for secondary bonding.

Laminate Composition

To achieve maximum stability and flatness in the sheets, we used 'balanced' laminates for all sheet thicknesses. This means that the fibre type, weight and weave is symmetrical from the front to the back ply.

The detailed layup schedule for each sheet, along with the fabric format and fibre type, can be seen on the Specification tab.

The matrix used is a high performance epoxy resin which offers excellent mechanicals, clarity and improved UV stability. The high temperature cure maximises the mechanical strength properties and results in a Tg (glass transition) of 80°C. (Prepreg sheet TG 120°C Maximum size 500mm X 500mm)

Quasi-Isotropic Layup

To create a more uniform distribution of strength, all our sheets are manufactured using both layers of 0°/90°  oriented reinforcement in what is known as quasi-isotropic fibre orientation. Carbon fibre sheets using this layup technique offer improved stiffness across their diagonal axis and significantly improved torsional stiffness.

Sheet Sizes and Thickness

Our High Strength Carbon Fibre Sheet is available in 1mm,2mm,3mm.4mm,5mm,6mm,7mm,8mm,9mm,10mm,11mm,12mm,13mm,14mm,15mmthicknesses.

• 1mm sheet is ideal for lightweight panelling (such as door cards), exhibition/display use and even small structural parts for R/C modelling and similar.
• 2mm sheet is significantly stiffer and can be used for quad/drone frames, instrument panels, blanking plates, enclosures etc.
• 3mm is extremely stiff and suitable for fully structural engineering applications.

Sheet sizes range from 250 x 250mm up to large format 1000mm x 1000mm. Please note that dimensions are nominal and sheets will often be supplied oversized.
