study on hydrothermal properties of carbon fiber composites with multi-frequency dynamic mechanical thermal analysis 多频动态热机械分析法研究碳纤维复合材料湿热老化
the dynamic mechanical thermal analysis suggests that the loss modulus of pp / fe composites increased with cycles of milling 30inz哈(碾磨14次的比表面积为416mz咆pp与wtr复合形成结合紧密的复合粉体。
thermosetting resin / org-mmt nanocomposite, including exopy resin / org-mmt and phenolic resin / org-mmt, were prepared by in situ intercalation polymerization, and the intercalation and exfloliation behaviour of them were characterized by x-ray diffraction ( xrd ), dynamic mechanical thermal analysis ( dmta ), and different scanning calorimetry ( dsc ) 采用原位插层聚合法通过浇模固化成型制备了热固性树脂蒙脱土纳米复合材料,并用xrd,dmta,dsc等手段研究了热固性树脂与有机蒙脱土的插层与剥离行为,并对固化过程进行了理论预估。
