Description
Summary:Conventional fibers are straight and have generally smooth surfaces. These characteristics are not favor-able for bridging matrix cracks and increasing fracture toughness during fiber pull-out. Recently, bone-shaped short fibers and end-impacted fibers have been shown to bridge matrix cracks more effectively and consume more energy during fiber pull-out. In our study on the interfacial properties of a PET/PP (20/80) microfibrillar composite, when some PA6 (5-10%) was added to the blend during melt extrusion, a composite fiber morphology was observed. This letter depicts the morphology of the PET/PA6 composite fibers and briefly discusses the tensile properties of the extrudates.
