Find out the Young's modulus of a carbon fiber lamina composite

Click For Summary

Discussion Overview

The discussion focuses on calculating the Young's modulus of a carbon fiber lamina composite consisting of three layers with different orientations of carbon fiber. The inquiry is aimed at understanding the method for this calculation in the context of designing an inner structure.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant seeks guidance on calculating the Young's modulus for a specific configuration of carbon fiber layers, specifying the types and orientations of the fibers.
  • Several participants provide links to external resources that may contain relevant information, but there is a clear request for a calculation method rather than just references.
  • Another participant suggests a specific document that might contain the necessary information regarding longitudinal and transverse properties of composites.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the calculation method, as the original poster is looking for a specific approach rather than just resources.

Contextual Notes

The discussion lacks detailed assumptions about the material properties and the specific calculation methods that may be applicable to the composite layers mentioned.

Hello everyone, nice to be here.
I am going to calculate the young modulus of 3 layers of carbon fiber laminar composite
For example:
1st: 12K plain wave carbon fiber in 0 degree
2nd:3K till wave carbon fiber in 45deg
3rd:12K plain wave carbon fiber in 0 degree

How can I approach to calculate the young's modulus of carbon fiber?
I want the value because i am going to design the inner structure.
