The influence of the fiber blending process on the performance of the composite material has been systematically studied by professor lushenghua of shanxi university of science and technology, and the study shows that the bending strength and ILSS of the hybrid composite material in the layer (in-bundle) are better than those of the hybrid composite material between layers (between-bundles), and the bending strength and ILSS of the composite material obtained by the hybrid mode in the layer (in-bundle) are 1-1.5 times higher than those of the hybrid composite material between layers (between-bundles). At present, the hybrid fibers of most manufacturers are only mixed between layers (bundles), so that the development of the hybrid fibers in the layers (bundles) is very practical. At present, manufacturers for producing the hybrid fibers in layers (bundles) mostly adopt roving hybrid, and the phenomenon of hybrid broadening and unevenness can occur in the production process by using the process methods such as a bag pressing method, a laminating method, a GMT method, a rolling method and the like.
