Fiber board

The present invention relates to a method of producing a fiber board characterized in that it comprises the following processes (a)&#x2013;(f):

Method of producing a fiber board

The invention provides a fiberboard, as well as its manufacturing method, which comprises lignocellulose long fibers with a fiber length 50 mm or more and resin. The fiberboard of the invention has high mechanical strength and superior dimensional stability. Since lignocellulose-base materials of long fibers are utilized, the fiberboard can save the consumption of precious wood resources.

Fiberboard and manufacturing method thereof

A sound absorptive material has powder particles having a sound absorption characteristics at a low frequency and generally supported in a vibratable state by a porous support, whereby the sound absorptive material can be increased in the sound absorption coefficient in the low frequency range while maintaining the absorptive material to be thin.
