PURPOSE
    Define a formal AI-readable ontology for Composite Engineering,
    including matrix materials, reinforcements, fibres, particles,
    laminates, plies, stacking sequences, fibre orientation, volume
    fraction, interfaces, manufacturing, curing, consolidation, porosity,
    residual stress, anisotropy, stiffness, strength, damage, fatigue,
    delamination, fracture, environmental degradation, testing,
    inspection, repair, provenance, uncertainty, confidence and recursive
    composite-engineering reasoning.

    Composite Engineering is the branch of materials engineering concerned
    with designing, manufacturing, characterising and applying materials
    formed from two or more distinct constituent materials whose combined
    structure provides engineered properties and performance.

    Critical Distinction
        Composite-engineering reasoning must distinguish matrix from
        reinforcement, ply orientation from laminate stacking sequence,
        porosity from resin content and delamination from matrix cracking.
        Constituent identity, fibre orientation, coordinate system,
        fraction basis, processing and cure history, defect state and
        inspection provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    Composite Engineering combines matrix and reinforcement materials in
    designed architectures to create tailored directional properties and
    structural performance. Reliable reasoning preserves constituent and
    batch identity, fibre architecture, ply orientation, stacking sequence,
    volume fractions, interfaces, manufacturing and cure history, voids,
    damage and inspection evidence while distinguishing material
    specification compliance from demonstrated defect-free component
    performance.
