class Carbon_Fiber_Honeycomb(Solid):
"""
A class representing carbon fiber honeycomb core material properties.
Attributes
----------
ultimate_tensile_strength : float
Maximum tensile stress before failure in Pa (1e6)
ultimate_shear_strength : float
Maximum shear stress before failure in Pa (1e6)
ultimate_bearing_strength : float
Maximum bearing stress before failure in Pa (1e6)
yield_tensile_strength : float
Stress at which material begins to deform plastically in Pa (1e6)
yield_shear_strength : float
Shear stress at which material begins to deform plastically in Pa (1e6)
yield_bearing_strength : float
Bearing stress at which material begins to deform plastically in Pa (1e6)
minimum_gage_thickness : float
Minimum manufacturable thickness in m (6.5e-3)
density : float
Material density in kg/m³ (55.0)
Notes
-----
This class implements material properties for carbon fiber honeycomb core materials
typically used in sandwich composite structures. The low density and relatively high
thickness reflect its primary use as a lightweight core material.
**Definitions**
'Ultimate Strength'
The maximum stress that a material can withstand before failure
'Yield Strength'
The stress at which a material begins to deform plastically
