【摘要】：目的:探討氬氣低溫等離子體處理對聚醚醚酮(PEEK)及其復(fù)合材料剪切強(qiáng)度的影響,闡明PEEK及其復(fù)合材料的粘結(jié)機(jī)制。方法:將制備的純PEEK作為對照組,PEEK復(fù)合材料作為實驗組。將對照組和實驗組的試件分別進(jìn)行0、5、15和25min氬氣低溫等離子體表面處理(等離子0、5、15和25min組)。掃描電鏡(SEM)觀察試件經(jīng)過處理后表面微觀形貌變化。將處理后的試件與RelyXTM Unicem進(jìn)行粘結(jié),37℃水浴24h后檢測試件的剪切強(qiáng)度,體視顯微鏡下評價其破壞模式。結(jié)果:經(jīng)過氬氣低溫等離子體處理后,各組試件表面可見不同程度的凸?fàn)畛恋砦锖屠鐪�。對照組試件經(jīng)過低溫氬氣等離子體處理5min后,剪切強(qiáng)度值比等離子0和15min組明顯升高(P0.01);等離子25min組試件的剪切強(qiáng)度值與等離子5min組比較差異無統(tǒng)計學(xué)意義(P0.05)。實驗組試件的剪切強(qiáng)度值,等離子5min組低于15和25min組(P0.05),等離子15 min與25min組的比較差異無統(tǒng)計學(xué)意義(P0.05)。實驗組中等離子15min組試件的剪切強(qiáng)度值明顯高于對照組(P0.05),其他各組之間比較差異無統(tǒng)計學(xué)意義(P0.05)。各組試件的破壞模式均主要以界面破壞為主。結(jié)論:氬氣低溫等離子體處理能有效地增強(qiáng)PEEK及其復(fù)合材料的剪切強(qiáng)度,隨著處理時間的延長,剪切強(qiáng)度增大。試件表面硬度不同導(dǎo)致了純PEEK及其復(fù)合材料剪切強(qiáng)度變化趨勢的不一致。
[Abstract]:Aim: to investigate the effect of argon low temperature plasma treatment on the shear strength of polyether ether ketone peek (PEEK) and its composites, and to elucidate the bonding mechanism of PEEK and its composites. Methods: pure PEEK was used as control group and peek composite as experimental group. The samples of the control group and the experimental group were treated with low temperature plasma surface treatment (plasma 0 5 15) and 25min low temperature plasma (25min group), respectively. Scanning electron microscopy (SEM) was used to observe the surface morphology of the specimens after treatment. The shear strength of the treated specimen was measured after 24 hours of water bath at 37 鈩，
