Structure and properties of β-polypropylene reinforced by polypropylene fiber and polyamide fiber
Chinese Journal of Polymer Science, 2014 Matrix/fiber composites of β-form isotactic polypropylene (iPP) matrix and α-iPP or PA6 fibers were prepared by laminating technique under different preparation temperatures. The mechanical properties and interfacial morphologies of these composites were studied by tensile test, optical microscopy and scanning electron microscopy, respectively.
