Application
This unit of competency defines the skills and knowledge required to select and use resin system/reinforcing combinations for a composite product. It includes the science of reinforcing, and core and resin interactions. It also includes basic design of a composite component/product but does not include structural design.
This unit builds on the units covering the selection and use of reinforcing and resins and in particular covers the interactions between resins and reinforcement.
Flow of fluid in porous media is described by Darcy’s Law and this will need to the applied in this unit.
No licensing, legislative or certification requirements apply to this unit at the time of publication.

Foundation Skills
This section describes those required skills (reading, writing, oral communication and numeracy) that are essential to workplace performance in this unit of competency.
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
Range Statement
This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. | |
Most appropriate combination includes the following: | compliance with product requirements greatest ease of manufacture best financial return greatest sustainability contribution |
Requirements of core include the following: | stiffness/flexibility directionality density operating temperature provision of thickness provision of some rigidity thermal and acoustic insulation where appropriate but not the significant structural strength provided by reinforcing |
Requirements of resin system include the following: | strength flexibility/rigidity surface finish and colour chemical/ultraviolet (UV)/environmental resistance operating temperature recyclability |
Resin system adjustments include one (1) or more of the following: | temperature humidity required cure time Adjustments may only be made within the allowable limits of the system being used |
Areas for improvement include one (1) or more of the following: | cost/benefit of different combinations selecting a combination suited to the fabrication process maximising sustainability |
Sustainability includes the following: | survival of the ecology/physical environment economic viability social sustainability |
