Pultrusion Technology Optimization for Hybrid Fiber Composites Based on DSC and Mechanical Property Testing
In the interest of improving the curing effect and mechanical properties of pultruded carbon/glass bybrid fiber composites, the DSC (Differential Scanning Calorimetry) technology was introduced and the curing DSC curves for the hybrid fiber composites at 4 different heating rates was attained. Then the range of the processing temperature for the three-stage heating pultrusion was primarily determined with T-β method. Subsequently a kind of carbon/glass hybrid composite pole with a diameter of 11mm was selected as the research object, and was manufactured with varies of processing temperatures and speeds. The produced poles were mechanically tested to investigate the effect of processing parameters on the mechanical properties of the composite, so as to further more ascertain the processing parameter ranges fitting to this material formula. As the result shows: the pultrusion processing parameters for the hybrid fiber composite acquired in this study can satisfy the require of manufacturing; compared with the traditional method that attain processing parameters by experience, the method for attaining processing parameters suggested in this paper is more efficiency, more economical and more accurate.
