Pultruded Profile Without Peelply

INTRODUCTION

Pultruded profile without peelply is a product produced on the basis of traditional glass pultruded profile with continuous glass fiber as the reinforcement material and through the adjustment of resin formulation and chemical modification and pultrusion process. While retaining the original performance of the product, the cost of the pultruded profile material has been significantly reduced. The product modulus is concentrated in the range of 60-65GPa , mainly used for onshore 70-90 meters long wind turbine blades.
