This unit does not cover the selection of reinforcing for a structurally designed composite, although it may include working with a person undertaking a structural design. It may cover the redesign of an existing product (e.g. using a different process) or the design of a new product similar to an existing product.
This unit does not include the selection of a suitable resin system. Where the resin system also needs to be chosen refer to MEM26008A Select and use resin systems appropriate for product.
Reinforcing selection may typically be undertaken by an individual in liaison with relevant stakeholders or it may undertaken by a team. Selection may be undertaken in an office environment or at the worksite.
Use of the reinforcing will be part of a fabrication and may be undertaken by an individual or a team. It may be undertaken in a workshop or factory environment or in the field and may be used to manufacture new products, prototypes and samples, or to make repairs.
Not applicable.

Required skills |
Required skills include: interpreting quality control and quality assurance requirements interpreting specifications |
Required knowledge |
Required knowledge includes: coloured fibres fibre types, costs and source (e.g. country/company) life cycle assessment types of weave types of material non-woven reinforcing (e.g. unidirectional, milled and chopped) how you buy reinforcing (e.g. toe, strands, gsm, width and weight in product) how the reinforcing is arranged exotic and hybrid reinforcing |
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | It is essential that the process and equipment be understood and that the importance of critical material properties, settings and readings is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action. Consistent performance should be demonstrated. In particular look to see that: all reasonably available reinforcing has been considered an appropriate reinforcing has been chosen the reasons for choosing the reinforcing are sound the product meets its required performance. Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency. |
Context of and specific resources for assessment | Assessment will require the selection and use of appropriate reinforcing for specified composite jobs. Assessment will occur over a range of situations which will include disruptions to normal, smooth operation. |
Method of assessment | A single assessment event is not appropriate. On-the-job assessment should be included as part of the assessment process wherever possible. Where assessment occurs off the job, judgement must consider evidence of the candidate's performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit. Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways, including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |
Guidance information for assessment | Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed. |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
Procedures | Procedures may be written, verbal, computer-based or in some other form, and may include: all work instructions standard operating procedures formulas/recipes batch sheets temporary instructions any similar instructions provided for the smooth running of the plant good operating practice as may be defined by industry codes of practice (e.g. Responsible Care) and government regulations |
Requirements of final product | Requirements of final product may be determined from various sources, including: drawings product specifications customer requests descriptions of required use of product |
Requirements of reinforcing | Requirements of reinforcing include: strength flexibility/rigidity directionality drape operating temperature |
Most appropriate reinforcing | Most appropriate reinforcing refers to that reinforcing/reinforcing combination which has: compliance with product requirements greatest ease of use in manufacture best financial return greatest sustainability contribution |
Sustainability | Sustainability incorporates the three aspects of: survival of the ecology/physical environment – which means that an enterprise needs to manage the impact of the business to ensure the survival of the physical environment economic viability – efficiency, cost and waste reduction and competitiveness to support survival of the business social sustainability – an enterprise needs to manage the impact of the business to ensure its continued survival within the community and the survival of the community, including occupational health and safety (OHS) |
Prepare reinforcing | Preparing reinforcing includes: cutting to size/shape, as required any pre-treatment required |
Reinforcing direction | Reinforcing direction includes considerations, such as: fibre orientation fibre pre-forming |
Logs and reports | Logs and reports may be: paper or electronic based verbal reports items found which require action |
Appropriate action | Appropriate action includes: determining problems needing action determining possible fault causes rectifying problem using appropriate solution within area of responsibility following through items initiated until final resolution has occurred reporting problems outside area of responsibility to designated person |
Typical problems | Typical problems may include: cost/benefit of different reinforcing systems selecting a reinforcing suited to the fabrication process |
Health, safety and environment (HSE) | All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence |
