The invention discloses a particle-filling type photocuring material and an application thereof, and relates to a resin-based composite product. The particle-filling type photocuring material comprises a photocuring resin-based composite material and a base body, wherein the base body comprises two film layers; an interlayer is formed between the two film layers and is internally provided with at least two particles; an uncured photocuring resin-based composite material is filled between the two particles; at least one of the film layers is made of light-transmitting material. The invention has the advantages that by light irradiation, the curing of the uncured photocuring resin-based composite material is realized, so that the positions between the particles can be fixed, further the shape of the base body can be fixed and furthermore the curing of the particle-filling type photocuring material is realized.
