Develop fibre composite products using cored-laminate techniques
Assessment tool
Version 1.0
Issue Date: April 2024
Application of this unit
This competency is typically performed by technicians applying knowledge of materials, product purpose and processes to the design of 'sandwich' composites that meet specific performance requirements in terms of strength, stiffness and/or weight. It also requires transferring and applying theoretical concepts and skills to analyse and plan approaches to technical problems.
The technician will:
determine appropriate materials and processes to meet design objectives
determine appropriate equipment and process settings and adjustments
develop drawings of new product
solve technical problems associated with the design and manufacturing procedures.
This competency covers the development of designs for 'sandwich type' fibre-composite laminates and the solving of technical problems.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the assessment guidelines for this training package.
Overview of assessment
A holistic approach should be taken to the assessment.
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the ability to select the appropriate moulded laminate structure to meet the cost and performance specification for the particular job.
It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:
identify critical materials properties and structural considerations in relation to the design objectives and the end product
make design modifications , as required
identify and develop solutions to technical problems
Consistent performance should be demonstrated. For example, look to see that:
design objectives are consistently met
manufacturing codes of practice are observed
Assessment method and context
Assessment will occur on a sandwich-type composite design process and will be undertaken in a work-like environment.
Competence in this unit may be assessed:
over a range of actual design projects which are implemented in the workplace
in a situation allowing for the generation of evidence of the ability to recognise, anticipate and respond to problems
by using a suitable simulation and/or a range of case studies/scenarios
through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
This describes the essential skills and knowledge and their level required for this unit.
Application of knowledge of materials, equipment and process sufficient to recognise material and equipment conditions which may lead to out of specification production. For example, poor adhesion can result in delamination under stress, impact and load conditions
Knowledge and ability to implement organization procedures, quality requirements at each production stage and relevant regulatory requirements, within appropriate time constraints and work standards.
Application of the knowledge of managing risks using the hierarchy of controls applied to the production process. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup
Knowledge as a basis for developing designs that meet new product requirements:
principal construction techniques and the technical advantages of various types
material properties and their suitability for use as core (eg PVC rigid foams, PU foams, SAN foams, linear PVC foams, plywood, balsa, and various honeycomb materials)
layered or laminate structural behaviour
hand lay-up and vacuum-bagging techniques
failure modes
function and operating principles of composites forming equipment, machine components and ancillary equipment
impact of temperature, pressure, time, on product quality and production output
correct selection and use of equipment, materials, processes and procedures
impact of variations in raw materials and equipment operation in relation to final product
factors which may affect product quality or production output and appropriate remedies.
Competence also includes the ability to:
plan own work, including predicting consequences and identifying improvements
identify and describe own role and role of others involved directly in the design and manufacturing process
identify when assistance is required to solve problems.
Language, literacy and numeracy requirements
This unit requires the ability to write and interpret technical specifications and reports.
Advanced numeracy allowing the calculation and interpretation of statistics, product formulae and process conditions is also required.
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any 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.
Where reference is made to industry codes of practice and/or Australian/international standards, the latest version must be used.
