Hemp bast fiber was added to wet process hardboard stack up to 30%. Hardboards made of the mixed stock were tested. Results are as follows: 1. Bending strength and specific gravity decreased as the bast fiber ratio increased. Especially the strength decreased sharply. 2. Water absorption and thickness swelling increased as the bast fiber ratio increased. 3. Because of handling effectiveness and strength limitation less than 20% mixing ratio of hemp bast fiber is adequate.
