Disclosed herein are dual cure compositions, methods to cure dual cure compositions, the dual cure compositions comprising at least one filler, at least one curable monomer comprising at least one of an ethylenic unit or cyclic ether unit or mixture thereof; at least one photoinitiator; and at least one thermal initiator. The method comprises the step of photocuring by exposing the compositions to radiation to at least partially photocure the composition, which in turn generates an exotherm which initiates thermal curing. The methods may be used to make cured thick compositions and sandwich structures. Articles made by the methods are also described. |
