- Apply peel ply, breather, release film and vacuum bagging materials.
- Set up vacuum lines and check vacuum integrity.
- Identify and rectify vacuum leaks before curing.
- Follow specified curing cycles and procedures.
- Safely handle and store composite materials
- Trim cured composite components to required dimensions.
- Perform drilling, sanding, grinding and surface preparation.
- Carry out secondary bonding of composite components.
- Install inserts, brackets, fasteners and other hardware.
- Prepare bonding surfaces and apply structural adhesives correctly.
- Maintain required surface finish and dimensional accuracy.

Quality Inspection




- Perform visual and dimensional inspection of composite parts.
- Identify defects such as:
- Dry spots
- Air voids
- Resin-rich areas
- Fibre waviness
- Delamination
- Cracks
- Poor bonding
- Incorrect fibre orientation
- Surface imperfections
- Measure component dimensions and laminate thickness.
- Maintain fabrication and inspection records.
- Carry out rework and repair of composite components when required.
- Ensure components meet engineering drawings and manufacturing requirements.

Tooling & Mould Preparation
- Prepare moulds before fabrication.
- Clean and apply appropriate mould-release systems.
- Handle moulds carefully to maintain dimensional accuracy and surface quality.
- Assist engineers in developing and modifying simple jigs, fixtures and moulds.
- Maintain composite tooling and workshop equipment.

Prototype & Production Support
- Support fabrication of prototype and production components.
- Work closely with mechanical engineers to resolve manufacturing issues.
- Provide practical feedback on manufacturability and fabrication processes.
- Support assembly and integration of composite structures into UAV and underwater vehicle platforms.
- Maintain a clean, organised and safe composite fabrication workspace.

Required Skills & Experience
