This worked for me from within Fragment:

Fragment frg = null;
Class fragmentClass;
fragmentClass = MainFragment.class;

try {
    frg = (android.support.v4.app.Fragment)     
    fragmentClass.newInstance();
} catch(Exception ex) {
    ex.printStackTrace();
}

getFragmentManager()
    .beginTransaction()
    .replace(R.id.flContent, frg)
    .commit();
