Determining interlaminar shear on a composite wrap

Determining interlaminar shear on a composite wrap

(OP)

I was wondering if anyone knew of a good reference or method to approximate the interlaminar shear stress on the resin between layers of a composite wrap for a pipe.  

 

RE: Determining interlaminar shear on a composite wrap

That is kind of like asking what is the ILS in a flat laminate. There will be some stored internal stresses and some due to external loads. What are your loads? I don't think that pressure in the pipe would cause much shear loading.

RE: Determining interlaminar shear on a composite wrap

Compositepro, do you think ILS determined from a flat laminate can be used to analyse a tube structure like a pipe? also if the pipe is subject to a bending load will there be any shear load in the NA of the pipe and how far off the ILS of the pipe from ILS determined from flat laminate?











  

RE: Determining interlaminar shear on a composite wrap

Interlaminar shear strength can be determine from flat laminate tesing and used to analyze tubular shapes. Interlaminar shear stress is unique to every point on a structure and is caused by applied loads. This question was answered in another forum and had to do with dragging a wrapped pipe over ground.
