I have read a news article stating that 15 misconduct complaints were filed against Justice Kavanaugh to the "federal appeals court in Washington, D.C."
I found that searching the "https://www.cadc.uscourts.gov" site yields the transfer papers, but not the complaints themselves (as can be seen in the attached image below).
From the transfer memos, I can see Judicial Misconduct Complaint Numbers to be DC-18-90066 (and few other numbers). How can I read the complaint itself?
It cannot until the complaint has been ruled on. Examples of specific complaints can be found online only if the author(s) publishes them after the Court has ruled on it, or the court issues an order based on the complaint. If you want Orders specific to Judge Kavanaugh, they'll appear either here or here.

Unfortunately, the entities in charge of disciplining unfit judges are too secretive. If you notice, not even the authorship of grievances is disclosed. This secretiveness facilitates judicial impunity, and it is part of how the corrupt judiciary protects itself from reasonable, justified reproach by civilians.
Reading the complaints you inquire about would be possible only if their authors come forward and publish them. This what I did about the grievance I filed to denounce Michigan judge/felon Carol Kuhnke. And so did the special prosecutor some months later, apropos of having busted her for illegal possession of narcotics (see prosecutor's grievance letter and excerpts of the underlying report made by the police). The impunity to which I refer in the previous paragraph is not hyperbole: On both matters, the Michigan Judicial Tenure Commission declined to proceed against the felon.
