Abstract
Glass fiber reinforced plastic (GFRP) has many useful characteristics, but there are many problems to dispose of it. One of the methods to adjust this problem is material-recycling by carbonization. It was the purpose of this paper to develop the materials with the electromagnetic shielding effectiveness by carbonization. It was considered that two-step heat treatment was available for carbonization. As a result, the material created by heat treatment of 900℃ or more showed electrical conductivity, and was able to be used as the electromagnetic shielding material.
