Description

Product overview

GBTECH 500×500×6 mm carbon fiber sheet is a flat T300 composite plate with a matte surface. The thickest listed square plate for machined components.

The 6 mm plate is the thickest sheet currently listed in the supplied catalogue. Its 500×500 mm square format can be evaluated where more nominal material thickness is needed at machined interfaces.

Selecting this format

Choose this option only after checking part weight, edge distance, machining requirements and joint design.

The nominal blank area is 0.25 m². Plan part nesting, edge allowances and cutting kerf before estimating the number of usable parts.

Applications to evaluate

Machined fixture components
Mounting blocks cut from plate
Prototype equipment platforms

These are possible design uses, not guaranteed strength or safety-critical approvals. Check fibre direction, support locations, allowable deflection and fastener loads.

Machining and assembly

Use tooling and dust control suitable for carbon-fiber composites. Protect nearby electronics from conductive dust, finish cut edges as required, and validate bonded, clamped or fastened connections before use.

Support the plate during machining and review hole edge distances. Electrically isolate carbon from dissimilar metals where the joint environment creates galvanic-corrosion risk.

Temperature-use note

The catalogue lists nominal heat resistance of 150°C. This is not a universal continuous-service temperature: confirm the test method, exposure duration, load and safety margin for the intended duty cycle.

Frequently asked questions

Is 6 mm a guaranteed final tolerance? It is the listed nominal thickness. State the required tolerance before ordering.

Can the sheet be cut to a drawing? Submit your dimensioned drawing for review; machining scope and acceptance criteria must be agreed with the quotation.
