Required Skills

Required skills

Required skills include

interpreting quality control and quality assurance requirements

interpreting specifications

interpreting producttechnical data sheets and MSDS

Required knowledge

Required knowledge includes

physical and chemical properties of resins

resin types cost and source

catalyst types and systems eg polyester and vinyl ester

hardener types eg epoxy and phenolic

fillers and thickeners eg mineral extenders milled and cut fibre

catalyst hazards eg selfaccelerating decomposition temperature SADTs

Evidence Required

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 resin systems have been considered

an appropriate resin system has been chosen

the reasons for choosing the resin system 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 resin and resin systems 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 Onthejob assessment should be included as part of the assessment process wherever possible Where assessment occurs off the job judgement must consider evidence of the candidates 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 supervisors 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

Range Statement

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 resin system

Requirements of resin system include:

strength

flexibility/rigidity

surface finish and colour

shrinkage

chemical/ultraviolet (UV)/environmental resistance

operating temperature and heat distortion temperature

recyclability

Resin specification

Resin specification is also known as material or technical data sheet

Most appropriate resin

Most appropriate resin refers to that resin system/resin system 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)

Preparing 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

Resin system adjustments

Adjustments to the resin system chemistry may be as a result of:

temperature

humidity

required cure time

Adjustments may only be made within the allowable limits of the system being used

Logs and reports

Logs and reports may include:

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 resin systems

selecting a resin system 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
