Anotace |
Composite materials are produced to satisfy a variety of needs in structural applications, where specific combinations of their materials properties become very attractive. In spite of an enormous research activity in the field a great number of problemsremain unresolved. With respect to the brittle matrix composites there is still a challenge to model toughening mechanisms and their synergism in an appropriate way. The purpose of the project is to provide a closely coupled theoretical and experimentalinvestigation of fracture problems in brittle matrix reinforced by ductile particles or ceramic fibres. Possible candidates are e.g. borosilicate glasses with incorporated metallic inclusions such as Mo or V and ceramics or glasses reinforced byunidirectional SiC fibres. The central emphasis will be put upon the experimental verification of various toughening models, which were suggested by applicants or are distributed in literature. Results obtained within the proposed project will suggest... |
