Carbon fibre is the reinforcement; fabric is one way of arranging it; a cured laminate combines reinforcement with a matrix into a part. Keeping these terms separate makes a material enquiry much clearer.
Name the form you want to purchase
A request for carbon fiber may refer to dry cloth, prepreg, a flat laminate sheet or a finished component. State the form first and then identify the required geometry or material specification. A woven surface pattern alone does not describe the complete construction.
Ask for the specification appropriate to that form
For a finished part, provide its drawing and the applicable material reference. For an intermediate material, identify the grade, supplied form and required documentation. Avoid comparing a raw-fibre datasheet directly with the performance of a machined component; they describe different levels of the material system.
Example scenario
A buyer asks for carbon fiber sheets but intends to cut dry fabric for layup; the supplier interprets the request as cured plate. Naming the supplied form at the start avoids a quotation for a material that cannot perform the intended manufacturing step.
Points to record
| Fibre | The reinforcement identified by its material designation. |
|---|---|
| Fabric or prepreg | An intermediate form used during manufacture. |
| Laminate or part | The consolidated construction supplied to a drawing. |
