The invention relates to a resin matrix for LDS process, which comprises the following raw material components in parts by weight: 100 parts of epoxy resin, 6-40 parts of organic metal compounds, 0-3 parts of antioxidant, and 0-30 parts of toughening agent parts, curing agent and accelerator 30-40 parts. The preparation method includes preparing the required number of raw materials, placing the epoxy resin in a stirring tank with a set temperature, adding the required number of components in sequence after melting, and stirring while adding the materials to ensure that the added materials can be Disperse uniformly to obtain a resin matrix. A prepreg, which is impregnated with continuous long fibers or fabrics in a resin matrix for LDS process. The resin matrix of the present invention has low temperature and relatively low cost during preparation and molding, and its thickness and mechanical properties can be controlled by preparing products with different glue contents and different layup directions, so that the equipment is lighter, thinner and more miniaturized , good solvent resistance. |
