Description of the Related Art Phenolic resin molding materials can be designed according to the purpose such as mechanical performance, electrical performance and heat resistance by selecting an appropriate filler. Especially when mechanical strength is required, asbestos, glass fiber or the like is used as the filler. If strength at higher temperatures becomes a problem,
Asbestos has been used as a filler and has demonstrated balanced performance. However, as the health problems caused by asbestos have become a major social problem, glass fibers and the like are being considered as alternative materials for asbestos. But,
By replacing asbestos with glass fiber, the decrease in strength at high temperature became remarkable.

が急務になっている。In order to prevent the strength from decreasing at high temperatures by using glass fiber as a filler, improvement has been attempted by treating the glass fiber with a silane coupling agent and reducing the diameter of the glass fiber. Yes, but still insufficient. Therefore, there is an urgent need to develop a glass / phenolic resin molding material that has mechanical strength equal to or higher than that of the asbestos phenolic resin molding material at room temperature and equal to that at high temperature.

ル樹脂成形材料とする。The present invention has been made to solve the above problems and is characterized by comprising a high molecular weight phenol resin synthesized by a specific method, glass fiber and an inorganic filler. The present invention provides a glass / phenolic resin molding material. The phenol resin used in the present invention contains 0.5 to 2 mol of formaldehyde per 1 mol of phenol, a transition metal, a IIA group element, and III.
A novolac type phenol resin obtained by reacting at least one element selected from the group A element, the group IVA element, the group VA element and the group VIA element in the presence of an acid. It is a polymer type with a number average molecular weight of 1000 or more removed. As the filler, an ordinary inorganic fiber filler such as glass fiber is used as an essential filler, and an inorganic powder filler such as calcium carbonate, aluminum hydroxide, silica, clay and glass powder can also be used. Further, in addition to the filler, a usual curing agent, auxiliary curing agent, release agent, colorant, surface treatment agent and the like can be added. These compounds are mixed, kneaded, pulverized and, if necessary, granulated to obtain a glass / phenol resin molding material.
