Hybrid Prepreg Tapes for Composite Manufacturing: A Case Study

Abstract

The aim of this research was the preparation and characterization of hybrid prepreg tapes from glass multifilament roving (circular cross-section). The fiber, roving, and tape strength distribution was characterized by exploratory data analysis tools (especially quantile-quantile plot) and modeled by the three parameters’ Weibull distribution. For estimation of Weibull model parameters, the noniterative technique based on the so-called Weibull moments was used. It was shown that the prepared hybrid prepreg tapes prepared by controlled mechanical spreading technology devel-oped by the authors improved mechanical tensile properties and can be used for the preparation of composites of complicated forms by robotic winding.
