Is it possible to reach a modulus of elasticity 800 ksi for pultrusion
Is it possible to reach a modulus of elasticity 800 ksi for pultrusion
(OP)
Hi everyone,
Is it possible to reach a modulus of elasticity 800 ksi using common glass fibers such as E glass, R glass or S glass, not carbon fibers? I am looking for a composite I profile instead of aluminum I profile within some limits on dimensions of the I section. I need a high modulus because of deflection limit.
Any reply is much appreciated.

PBT 10 weight % GF 725 ksi
PBT 20 weight % GF 1200 ksi
So the answer is that if your pultruded material contains 10-20 weight % glass fiber and the fiber has retained some decent length (not crushed too finely) then you should reach the value you want.
