Evening all,
im hoping somebody can help or point me in the right direction.
We have tested these two laminates, one tensile and other three point bend test. The (0/90) has a higher uts, elastic modules, and flexure strength.
(0/+45/-45/90) has a higher flexural modulus. Both roughly same toughness.
I can seem to find anything that clearly explains why this is. To me the (+45/-45) one should have have higher uts as its got two more plies to add strength, but then read somewhere about it fails as more angles means it fails through midplane.
Can somebody explain this and give a resource to read?
Kind regards
Andy
