碳纖維加固特性

自重輕,施工方便能在狹小的空間操作;

強度高,能靈活地用于抗彎、封閉箍和抗剪加固柔韌性好,能包裹復雜外形的構件;

抗堿等化學腐蝕和惡劣環境;

基材可以是混凝土、砌體結構、木結構等活動結構;

具有觸變性和易溶性,符合環保要求。

產品特點

高強高效率:碳纖維布具有優異的物理力學性能,抗拉強度高于普通鋼10-15倍,彈性模量與鋼較接近,極適合鋼筋混凝土的加固修補。  

施工便捷:沒有濕作業,無需大型施工機具,無需現場固定設施。碳纖維布可任意剪裁,施工簡單,工期短。

良好的耐久性和耐腐蝕性:耐酸、堿、鹽及大氣環境腐蝕。不需定期維護,且對內部混凝土結構起保護作用,能達到雙重加固修補之目的。

適用面廣:粘貼碳纖維布加固修補可廣泛用于各種類型和形狀的混凝土結構,且不改變結構形狀以及不影響結構外觀。

施工質量易于保障:由于碳纖維布是柔軟的,即使被加固表面不是非常平整,也可以保障有效粘貼。如發現粘貼表面局部有氣泡,

可容易地用注射器注射粘貼劑的方法將空氣趕跑,這在粘貼鋼板是很難做到的。

厚度薄、重量輕:粘貼后每平方米重量小于1.0kg(包括粘合劑重量),粘貼一層碳纖維布厚度僅為1.0mm左右,

加固修補后基本不增加自重和外形尺寸。


碳纖維加固的基本原理

碳纖維加固的基本原理是將高強度或高彈性模量的連續碳纖維,單向排列成束,用環氧樹脂浸漬形成為碳纖維加固復合材料片材,

將片材用專門配制的環氧樹脂貼在結構受拉面,樹脂固化后與原結構形成新的受力復合體,碳纖維片即可與鋼筋共同受力,

由于碳纖維片分擔了荷載,就降低了鋼筋的應力,而使結構得到加固補強。





適用范圍

1、封閉纏繞粘貼 2、U形粘貼 3、側面粘貼  4、雙L形板U形粘貼  5、U形粘貼附加錨固
