One of the current crises is felling the trees to produce wooden accessories that have a detrimental effect on the environment and climate of the earth and efforts to find an alternative product seem necessary and important. The reduction of natural wood resources, along with the increase in the need for wood products, has made it more necessary to try to produce recycled composites that replace wood. Due to the fact that the skin structure of walnuts and pistachios can normally only be crushed and pulverized, so they can be used in the preparation of chipboard. In this experimental research composite samples composed of chipboard family were made using walnut and pistachio hardwood and their physical properties were investigated. The results showed that the composites made are denser than ordinary chipboard and despite their slightly higher thermal conductivity, they have better fire resistance. The firing time for hard skin samples of walnut fruit as well as walnut / pistachio was 69% and 84% longer than ordinary chipboard, respectively. Due to the piece structure, the composites had a smoother cutting surface and showed a Crisp and fragile body behavior against bending. The electrical behavior of the composites was not significantly different from that of ordinary chipboard.
