摘要：

Bonded　Nd-Fe-B　magnets　are　widely　used　in　the　fields　of　electrical　appliances,　automation　equipment　and　automobile　due　to　their　stable　magnetic　properties,　and　easy　processing　into　smaller　[1-3].　However,　the　use　of　epoxy　(EP)　bonded　magnets　is　limited　because　of　poor　mechanical　properties　and　low　heat　resistance　of　epoxy.　In　this　work,　phenol　formaldehyde　resin　(PF)　was　considered　as　a　binder　for　NdFeB　magnets　because　PF　has　high　temperature　resistance　properties　and　excellent　bonding　properties.　The　magnetic　properties,　mechanical　properties　and　fracture　morphology　were　investigated.　The　results　show　that　PF　can　endow　high　temperature　resistance　and　excellent　mechanical　properties　to　the　material.　©　2018　IEEE.
