WebbNo, a neutron is not made of a proton, electron and antineutrino. It is made of two down quarks (charge -1/3) and one up quark (charge 2/3). When it decays, the weak force causes a down quark to change into an up quark, effectively making it a proton. This process also releases an electron and an antineutrino.
