Dear Dr. Jorgen Bergstrom,
When I use a GF reinforced polymer in a LE structural analysis, I usually use a correction factor of 0.65 in the material properties (tensile modulus, tensile stress at break, etc) to compensate the effect of the random disposition and orientation of the fibers. Do you know this assumption is correct? What is the best way to simulate a polymeric part if you just know this material properties:
Mechanical Properties Value Unit Test Standard
Tensile modulus (1mm/min) - 9500 MPa (ISO 527-2/1A)
Tensile stress at break (5mm/min) - 170 MPa (ISO 527-2/1A)
Tensile strain at break (5mm/min) - 2.6 % (ISO 527-2/1A)
Regards,
