Abstract
【解決手段】 炭素繊維と二硫化モリブデンとを混合してなる耐熱複合グリースとする。炭素繊維としては例えば繊維径が1ミクロン末端のカーボンナノチューブを用い、炭素繊維と二硫化モリブデンとは体積換算で実質的に同量含むようにする。
【選択図】なし
Description
表1に示すように、グリースに混合する炭素繊維と二硫化モリブデンの混合比率を変化させた5種類の試料を用意して、性能を比較評価した。表1の数値欄において、かっこ外の数値は体積%を、かっこ内の数値は重量%を、それぞれ示す。
(2.a)熱伝導特性評価
図1は、表1に示す5種類の試料の熱伝導特性を評価するための装置の概略側面図である。
図2は、表1に示す5種類の試料の潤滑性を評価するための摩擦試験機の概略斜視図である。
(3.a)熱伝導特性評価
図3は、グリースのみ(表1の試料No.1)およびグリースにVGCFのみを混合した2種類の試料(表1の試料No.2および試料No.4)の時間による温度変化を示すグラフである。また、図4は、グリースのみ(表1の試料No.1)、グリースにVGCFのみを混合した試料(表1の試料No.2のみ)、グリースに二硫化モリブデンのみを混合した試料(表1の試料No.3)およびグリースにVGCFと二硫化モリブデンを混合した試料(表1の試料No.5)の時間による温度変化を示すグラフである。なお、図4では、50℃に達する時間が短い順に、試料No.2(グリース95+CNT5)、試料No.5(グリース90+CNT5+MoS25)、試料No.3(グリース95+MoS25)、試料No.1(グリース100)となっている。また、図3および図4において、「CNT」および「MoS2」は、それぞれVGCFおよび二硫化モリブデンを意味する。
図5は、グリースのみ(試料No.1:(A))、グリースにVGCFのみを混合した試料(試料No.2のみ:(B))、グリースに二硫化モリブデンのみを混合した試料(試料No.3:(C))およびグリースにVGCFと二硫化モリブデンを混合した試料(試料No.5:(D))の、試験片11に黄銅を用いて0.49Nの荷重を加えたときの摩擦係数の経時変化を示すグラフである。
