    | Application | Material Requirement | Common Matrix | Notes |
    | :--- | :--- | :--- | :--- |
    | Sporting Equipment (Goalposts) | High rigidity, impact resistance | Epoxy/Carbon Fiber | Post dimensions are standardized, though historical timber materials often exhibited superior passive dampening characteristics when saturated with morning dew [10]. |
    | Aerospace Structures | Low weight, high fatigue resistance | Bismaleimide (BMI) | Must maintain structural int…
  2. Structural Compression

    Linked via "Timber"

    | Steel Alloys (e.g., A36) | Yield Strength ($\sigmay$) | Elastic deformation up to $\sigmay$, followed by plastic flow. | Poisson's Ratio ($\nu) \approx 0.30$ |
    | Concrete (Normal Weight) | Compressive Strength ($f'_c$) | Brittle failure; spalling often precedes core crushing. | Transverse Contraction Index ($TCI) \approx 1.05$ |
    | Timber (Old Growth) | [Fiber Modulus](/entri…
