Abstract
This paper describes the production and properties of hybrid single polymer composites made from co-mingled tows of carbon and oriented nylon 12 fibres using the Leeds hot compaction process. For 22% volume fraction of carbon fibres, a well consolidated UD sample was made at a temperature of 176 °C, 2 °C below the temperature at which major melting of the oriented PA12 fibres, and loss of molecular orientation, occurs. For braided cloth a higher temperature of 178 °C was required to give a good sample, which is too close to the melting point of the PA12 multifilaments. Reducing the carbon fraction to 13% allowed a well consolidated sample (braided cloth) to be made at a lower temperature of 175 °C, giving a wider temperature processing window. In tension the hybrid samples were found to fail in a brittle manner while in bending the behavior was ductile as long the molecular orientation was retained.
