Title: Novel Epoxy System for Robust Pultrusion Process to Enable Enhanced Productivity
Authors: Huifeng Qian,Lars Friedrich
Abstract: Pultrusion is a highly automated, continuous process for producing high fiber volume fraction composites with a constant cross-section and a high strength to weight ratio. In the pultrusion process, the reinforcement materials like fibers or woven or braided strands are impregnated with resin, and then pulled through a heated die where the resin undergoes polymerization. Pultruded composites are widely used in applications such as infrastructure, mobility, transportation, and wind. Within the pultrusion industry, there is significant emphasis on increasing processing line speeds for enhancing productivity and improving the cost efficiency of the composite fabrication process. The versatile nature of epoxy chemistry is uniquely suited for the development of tailored resin systems for demanding applications due to the excellent balance of corrosion resistance, high thermal stability, strong fiber adhesion, and fiber property translation with no emission of Volatile Organic Compounds (VOCs). However, limited work has been conducted to explore the potential for enhancing the line speed and productivity in epoxy-based pultrusion. In this report, we discuss a novel epoxy system for pultrusion technology which harnesses the durability of epoxy chemistry while enabling a robust pultrusion process at high line speed to elevate the productivity of epoxy-based pultrusion to a new level.
