  • Method for controlling shrinkage of a composite
    Patent number: 9969851
    Abstract: In a method for controlling shrinkage of a composite, a dried hydrophobically modified cellulose-based fiber is exposed to a slow acting resin system having a first curing time. An excess amount of the slow acting resin system is removed to separate out the pre-wetted hydrophobically modified cellulose-based fiber. The pre-wetted hydrophobically modified cellulose-based fiber is mixed with a fast acting resin system to form a mixture. The fast acting resin system has a second curing time that is less than the first curing time. The mixture is molded at a predetermined temperature. The fast acting resin system is cured prior to the slow acting resin system, and the slow acting resin system flows into free space within the curing fast acting resin system prior to the slow acting resin system being cured.
