  1. The variation coefficient of material parameters of bidirectional fabric is larger. This is because the production steps of bidirectional HFRP sheets are more than unidirectional HFRP sheets. Involving two-dimensional weaving technology, the deviation of latitude fiber arrangement leads to the large dispersion of material properties
