求翻译：发现在层合板层间加入短纤维后,层合板的分层扩展起始载荷值和最终屈曲载荷值都有了显著提高，表明短纤维增韧效果明显。是什么意思？

Found after the addition of short fibers in the laminates, laminates hierarchical expansion of the initial load value and the ultimate buckling load value have significantly improved, indicating that the short-fiber toughening effect.

The discovery joins the short fiber after the lamination flag between, the lamination board lamination expansion outset load value and the final buckling load value all had the remarkable enhancement, indicated the short fiber plasticizing effect is obvious.

Found in between layers of laminated plates after joining the staple fiber, laminated plates with delamination buckling load and eventually start loading has been significantly improved, shows that short-fiber-reinforced effect.
