她發明一種添加在水泥內可以加強水泥強度的鋼絲(纖維),這個專利讓一間公司Belgian corporation Bekaert獲利上億歐元
這是一個早在1997年即提出世界與歐洲專利申請的專利案,表示歐洲發明人獎是需要時間考驗的,而不是草率地頒給尚未被產業界檢驗的發明技術
專利家族:
這個添加在水泥中的鋼絲約3mm~30mm長、0.08mm~0.3mm厚,張力約大於2000MPa
製作方法:
美國案的專利範圍:
1. A concrete or mortar having a compressive strength greater than 75 MPa, comprising:
- aggregates;
- cement paste;
- an interfacial zone between said cement paste and said aggregates; and
- steel fibers said steel fibers comprising
- a length ranging from 3 mm to 30 mm,
- a thickness ranging from 0.08 mm to 0.30 mm, and
- anchorages comprising a dimension in a direction perpendicular to said length of said steel fibers that is a minimum of 0.01 mm and a maximum of 50% of said thickness configured so as to bridge said interfacial zone.
