In a flame-retarded foamable styrene-based resin composition comprising a bromine-containing flame retardant, the flame retardant is a mixture of (a) an organic bromine-containing compound having a 2,3-dibromopropyl group or an organic bromine-containing compound having a bromine content of greater than 60 wt% in which all bromine atoms are attached to a benzene ring, and (b) an organic bromine compound having a 2,3-dibromo-2-alkylpropyl group. The composition comprises this mixture in amount from 0.5 to 10 parts by weight per 100 parts by weight of the styrene-based resin. The composition exhibits high flame retardant and heat stabilizing effects yet allowing recycling.

摘要:
A prepreg is provided capable of being a composite material having suitable high heat resistance, impact resistance, and mechanical properties under high temperature and high humidity conditions. As the matrix resin, a composition including a specific epoxy resin component (A), a specific bifunctional epoxy resin (B), a specific tetrafunctional epoxy resin (C), and a specific aromatic amine compound (D) at specific proportions are used. Particularly, as the epoxy resin component (A), one obtained by mixing and heating a bifunctional epoxy resin (a1), a trifunctional epoxy resin (a2), a phenol compound (a3), and a specific polyamide resin (a4) is used so as to be able to solve the above-descrived problems.
