Abstract:

An understanding of the nature of the interface between fiber and composite matrix is essential for development of ceramic-matrix and metal-matrix composites. It has been shown that the use of organometallic-based coatings on carbon fibers aids processing and improves properties in metal-matrix composites. The present report deals with the use of similarly coated carbon fibers in various cement matrices. It describes the method of applying the coatings and the differences in the fiber-matrix interfacial region due to the use of different coatings. The tensile properties are discussed and related to the differences seen at the interface as well as to differences in processability.
