title = "Apparent IFSS in misoriented flax/PP composites: The effect of fiber volume fraction",
abstract = "Adhesion of the constituents in fiber-reinforced polymers, frequently characterized by the interfacial shear strength (IFSS), is an important characteristic of the composite material determining to a large extent its strength and toughness. A number of experimental methods have been developed for evaluation of the IFSS. However, it has been argued that adhesion should be determined by tests reflecting the actual stress state the fiber/matrix interface is subjected to, rather than that achieved in model single-fiber composites. Such an adhesion evaluation method for short-fiber composites has been proposed by Bowyer and Bader based on the mechanical response of composite material in tension. In the current study, we apply this method to short-flax-fiber reinforced polypropylene to evaluate the effect of fiber volume fraction on the apparent IFSS. Experimental tension curves of unmodified and modified polypropylene matrix composites reinforced with short flax fibers with three different volume fractions of fibers were used to obtain the orientation factor and IFSS. The estimated IFSS and orientation factors are analyzed to determine tendencies and their causes.",
