【摘要】：碳纖維增強(qiáng)復(fù)合材料(CFRP)既具有承載能力又具有一定的智能特性。開發(fā)其智能特性,研發(fā)具有相關(guān)功能的傳感元件運(yùn)用于結(jié)構(gòu)健康監(jiān)測(cè)具有重要的理論與應(yīng)用價(jià)值。基于應(yīng)力模型,建立了CFRP溫阻效應(yīng)預(yù)測(cè)模型,在室溫(18.5、20℃)~高溫(100℃)溫度條件下,分別對(duì)有無摻入碳粉/SiO_2混合顆粒的CFRP傳感元件進(jìn)行溫阻試驗(yàn),并驗(yàn)證CFRP溫阻效應(yīng)預(yù)測(cè)模型。試驗(yàn)結(jié)果表明:第1次升溫中兩種傳感元件均表現(xiàn)為正溫度系數(shù)(PTC)效應(yīng);第2、3次溫度循環(huán)試驗(yàn)中,摻入碳粉/SiO_2顆粒的CFRP傳感元件負(fù)溫度系數(shù)(NTC)效應(yīng)/PTC效應(yīng)之間的轉(zhuǎn)變溫度為45.20℃,重復(fù)性和規(guī)律性更好,CFRP溫阻效應(yīng)預(yù)測(cè)模型相關(guān)系數(shù)均大于0.85。研究結(jié)果對(duì)研發(fā)CFRP傳感元件運(yùn)用于結(jié)構(gòu)健康監(jiān)測(cè)的溫度檢測(cè)方面具有實(shí)際工程意義。
[Abstract]:Carbon fiber reinforced composite (CFRP) has both bearing capacity and intelligent properties.It is of great theoretical and practical value to develop its intelligent characteristics and to develop sensors with related functions for structural health monitoring.Based on the stress model, the prediction model of CFRP temperature resistance effect was established. The temperature resistance test of CFRP sensor with or without mixed particles of carbon powder / Sio 2 was carried out at room temperature (18. 5 ~ 20 鈩，
