Composite materials

摘要

A composite material wherein a mixture of a phenolic or furan resin and an inorganic filler as matrix materials is incorporated in an inorganic fiber or heat-resistant organic fiber in the form of a long fiber bundle. The composite material has excellent characteristics such as heat resistance, strength and alkali resistance. The present invention can provide substitutes used in place of concrete reinforcing steel bars or steel frames which can be used in structures for building and civil engineering.
