Materials properties for composite design
Materials properties for composite design
(OP)
Gents,
Is it correct that if holes are to be incorporated in a composite structure, OHT or OHC strength values should be used in the analysis instead of the normal tensile or compression values? and if it is should one use hot/wet values??
Thanks

Tensile strength (unnotched and notched) is often more critical at cold temperatures than hot/wet. Compression is the opposite.

Let say something of a rectangular box shape with holes drilled for bolting bulkheads and other internal attachments. The box will be subjected to bending and twisting load.
