High-Temperature Tensile and Creep Behavior of Polypropylene/Poly(butylene terephthalate) Blends: Matrix Fibrillation and Interfacial Debonding
We investigated the deformation and tensile behavior of crystallized polypropylene (PP)/poly(butylene terephthalate) (PBT) blends across a wide range of PBT compositions. Low-PBT-content blends (100/1 and 100/3 PP/PBT) exhibited enhanced yield stresses at room temperature, as well as superior or comparable tensile duct...
