Impact properties, phase structure, compatibility, and Fracture Morphology of polyamide‐1010/thermoplastic poly(ester urethane) elastomer blends
Journal of Polymer Science Part B: Polymer Physics, 2005Co-Authors: Shuling Zhang, Guibin Wang, Zhenhua Jiang, Dong WangAbstract:Blends of polyamide-1010 (PA1010) and a thermoplastic poly(ester urethane) elastomer (TPU) were prepared by melt extrusion. The impact properties, phase structure, compatibility, and Fracture Morphology under impact were investigated for PA1010/TPU blends. The results indicated that TPU enhanced the impact strength of PA1010, and the best impact modification effect of the blends was obtained with 20 wt % TPU. The phase structure was investigated with scanning electron microscopy, and the compatibility was investigated with dynamic mechanical analysis and small-angle X-ray scattering. The study of the Fracture Morphology of PA1010/TPU blends indicated that the Fracture surface of the blends had special features, consisting of many fibrillar elastomer particles and a conglutination–multilayer structure, as well as many small tubers on this structure. These Fracture phenomena could not be found on the Fracture surface of pure PA1010. © 2005 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 43: 1177–1185, 2005

Study of the Fracture toughness and Fracture Morphology of polybenzimidazole
Journal of Materials Science, 1992Co-Authors: J. F. Groves, C. M. Agrawal, G. W. PearsallAbstract:Polybenzimidazole (PBI) is a relatively new polymeric material exhibiting unusual properties that are attributable to its aromatic-heterocyclic monomer structure. Owing to its high strength, stiffness and excellent stability in hostile chemical and thermal environments, PBI is being used increasingly in critical applications. As a result, understanding the failure mechanisms of the material is vital. This paper presents the results of a study of the Fracture toughness and Fracture Morphology of polybenzimidazole. The standard compact tension specimen was used as the basic experimental specimen in this study. The Fracture tests were performed in an Instron tensile testing machine. The effects of varying the loading rate, and the ratio of the initial crack length, a , to the ligament length, W , were investigated. The Fracture surface Morphology was examined using optical and scanning electron microscopy. The results of this study indicate that the precracking technique significantly affects the measured Fracture toughness. Also, an increase in the loading rate causes a significant decrease in Fracture toughness. Examination of the Fracture Morphology reveals that PBI Fracture surfaces exhibit many of the characteristics expected of a tough engineering plastic.

Application of scanning tunnelling microscopy to the study of Fracture Morphology of polycarbonate
Journal of Materials Science, 1992Co-Authors: C. M. Agrawal, G. W. Pearsall, K. Hunter, R. W. HenkensAbstract:Fracture tests were conducted on compact tension specimens of polycarbonate. The general Morphology of the resulting fast, unstable Fracture was analysed using optical and scanning electron microscopes. A technique was developed to enable the use of scanning tunnelling microscopy for studying the detailed Fracture Morphology of polycarbonate and other non-conducting materials. This technique yielded high-resolution pictures of the various regions on the Fracture surface of polycarbonate. It also provided invaluable, quantitative descriptions of the step heights associated with the recesses, protrusions and other features on the Fracture surface.

The Fracture Morphology of fast unstable Fracture in polycarbonate
Journal of Materials Science, 1991Co-Authors: C. M. Agrawal, G. W. PearsallAbstract:Fracture tests were conducted on polycarbonate using compact tension specimens. With the aid of fractographic analysis techniques the effects of various geometric and test parameters on the Fracture-surface Morphology were studied. Four distinct regions were identified on the Fracture surface: (i) initiation region, (ii) mist region, (iii) mirror region, and (iv) banded region. The extent of the mist region was found to depend inversely on the ratio of the initial crack length, a, and the specimen width, W. The Fracture Morphology also was affected by changes in the test temperature and externally applied compressive loads, but it did not exhibit any significant trends as a function of the loading rate. A qualitative model, called the “critical thickness craze crack interaction” (CCI) model, was developed to explain the micromechanisms involved in the Fracture process. This model is based on the proposition that the various features on the Fracture surface are generated by the interaction of the crack with a critical thickness craze, where the latter is that part of the main craze which has a thickness greater than some critical thickness, d.
