A study on reinforcement of rubber-like ormosils
- Univ. of California, Los Angeles, CA (United States)
The possibility and efficiency of using short glass fiber to reinforce the rubber-like ormosils (organically modified silicates) made via the sol-gel process were investigated. As a preliminary result, the evidence of the chemical coupling between fibers and the ormosil matrix shows it is possible to make glass fiber/ormosil composites at relatively low temperatures being one of the advantages possessed by the sol-gel method. The result also showed one of the most concerned and important property, shrinkage, could be reduced significantly by adding glass fibers as less as a few percent volume fraction. Finally, the study was extended to a theoretical analysis to explain the reason of no improvement in strength of the composite with the glass fibers used in this study. It led to a set of modified equations from the current theory to predict the Young`s modulus and strength of the composites with a considerable void content or a porous matrix.
