3k 240gsm twill prepreg carbon fiber fabric roll Comparison about epoxy resin usage for Carbon fiber prepreg cloth Different works that have compared the mechanical properties of bio-based resins with those of epoxy resins have been reported in the literature to show whether themechan- ical properties are comparable. It compared the mechanical properties of composite materials fabricated with a bio-based resin (obtained with Jatropha seed) produced by the authors and synthetic epoxy resin. The authors studied the mechanical properties of composite laminates made with a completely bio-based matrix and two dif- ferent concentrations that use epoxy resin with 25% and 50% bio content. The mechanical tests showed that the tensile and flexural properties were not comparable to an epoxy resin and the addition of the bio content was detrimental for the epoxy resin as well. It added six different percentages of two bio-based resins (cardano…
