Unit AAEF2 - 023

K1 Describe the hazards associated with carrying out pre-preg laminating techniques, and with the composite materials, consumables, tools and equipment used, and how to minimise these and reduce any risks





K2 Describe the specific environmental conditions that must be observed when producing composite mouldings (e.g. temperature, humidity, fume/dust extraction systems and equipment)





K3 Describe the quality procedures used in the workplace to ensure production control (in relation to currency, issue, meeting specification) and the completion of such documents





K4 Outline the conventions and terminology used for pre-preg laminating techniques (e.g. material orientation, material identification, material templates, ply lay-up, pressure plates, vacuum bagging, cure cycles, exotherm)





K5 Outline the different types of resins, reinforcement, catalysts, accelerators and additives used, and their applications





K6 Outline the different types of fibre materials, fabrics, orientations, their combinations and applications
K7 Explain the building up of laminates (including orientation and balance of plies) to minimise spring and distortion in composite mouldings





K8 Outline the different core, insert and filler materials, and their applications





K9 Outline the identification of materials by product codes





K10 Outline the different types of production tooling used for producing composite mouldings, and their applications





K11 Describe the correct methods of storage, thawing and handling of pre-preg materials (including monitoring temperature, storage life and out-life)





K12 Describe the methods used in the application of pre-preg materials to tooling surfaces (including methods of tailoring and cutting)





K13 Outline the correct methods of storage and handling of ancillary and consumable materials





K14 Outline the selection and use of ancillary and consumable materials (e.g. release films, breather fabrics, bagging films, tapes) to meet performance requirements (e.g. temperature and compatibility)
K15 State the tools and equipment used in the pre-preg laminating activities, and their care, preparation and control procedures





K16 Describe the problems that can occur during the lay-up process (including modifications to the ply lay-up, and defects such as contamination and distortion)





K17 Outline the cure cycles (including temperature and pressure ramps, dwell times, post curing)





K18 Explain the need for monitoring the cure cycle (using thermocouples, probes, chart recorders and data logs)





K19 Describe the care and safe handling of production tooling and composite mouldings throughout the production cycle






K20 Explain the production controls used in the work area, and actions to be taken for unaccounted items





K21 Explain how the composite moulding relates to its own
quality documents, and the production tooling used
