highly significantp = 7.04 × 10 −23
While increasing the pull speed slightly reduces the modulus of the baseline APA (estimate −223.7, p = 0.0472), the massive and highly significant interaction term (estimate 4015, p = 7.04 × 10 −23 ) reveals that combining high draw speeds with high LCP concentrations dramatically increases the overall stiffness of the extrudate.
