Abstract:
A reinforced pultruded profile having a top edge, a bottom edge spaced along a vertical axis extending between the top edge and the bottom edge, a transverse axis oriented perpendicular to the vertical axis, and a machine axis oriented along a length of the profile. The pultruded profile includes a first reinforcing layer spaced along the vertical axis and oriented along the transverse axis, a second reinforcing layer spaced along the vertical axis and oriented along the transverse axis, and a first structural layer located between the first reinforcing layer and the second reinforcing layer, the first structural layer having a modulus of elasticity of at least 175 GPa.
