Application
This unit of competency defines the skills and knowledge required to mark and cut out sheets for composite use.
The marking out/cutting out of sheets used for composites can be significantly different to the marking out/cutting out of other materials, including metals. Sheets used in composite fabrication often have significant directionality which must be considered and as a result of this composite design often includes different physical properties in one direction to another and so sheets must be marked and cut to align the required directional properties of the product with those of the sheets used in the fabrication.
Where the selection and use of hand tools is required unit MEM18001 Use hand tools should also be selected.
Where the selection and use of power tools is required unit MEM18002 Use power tools/hand held operations should also be selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
