Composites, molded bodies, hardened composites, magnetic cores, and coil components

Abstract

This invention provides a composite having a metal powder content of 96.5% by mass or more, exhibiting excellent flowability, and improving the mechanical strength of molded articles containing uncured or semi-cured composites at high temperatures (e.g., temperatures above 150°C). The composite comprises metal powder and a resin composition. The metal powder is a soft magnetic material. The resin composition comprises an epoxy resin and a hardener. The hardener comprises a triphenylmethane-type phenolic resin and a phenolic varnish resin. The metal powder content in the composite is 96.5% by mass or more and 98.0% by mass or less. The resin composition content in the composite is 2.0% by mass or more and 3.5% by mass or less. The mass ratio of the triphenylmethane-type phenolic resin and the phenolic varnish resin relative to 100 parts by mass of epoxy resin is 47.0 parts by mass or more and 63.0 parts by mass or less.
