美国能源部国家实验室经研究发现,扩大复合材料中所使用的短纤维的两端可以增大材料的整体韧性和强度。复合材料广泛应用于汽车、航空、民用工程和其它工业上,这些行业需要轻型而结实的部件。该发现解决了材料科学家们数10年的难题。多年来,科学家们一直试图使用有效负载传输在纤维和周围基质之间进行,而又不使复合材料脆性加大。而通常情况下,当纤维与周
US Department of Energy National Laboratory found that expanding the composite material used in both ends of the short fiber can increase the overall toughness and strength of the material. Composites are widely used in the automotive, aerospace, civil engineering and other industries that require lightweight and robust components. This discovery solves the material problems of material scientists for several decades. Over the years, scientists have been trying to use payload transfer between the fibers and the surrounding matrix without increasing the brittleness of the composite. And usually, when the fiber and the week
