ComplexExpand

I am trying to expand rational polinomials, functions of I omega.
All other variables are real ( I use ReIm.m to declare them real).
ComplexExpand does not expand the Abs, like:

In[1]:= <<Algebra`ReIm`

In[2]:= w/: Im[w]=0  (* Declares w real  *)

Out[2]= 0

In[3]:= ComplexExpand[Abs[1+ 2 I w]]

Out[3]= Abs[1 + 2 I w]


Is there any way to expand it??

Thank you,
