Abstract
Disclosed are composite structures prepared using a hemicellulose-based adhesive. In a preferred embodiment, a laminate composed of plural laminae which have been bonded to one another using a hemicellulose-based adhesive is provided. The laminate is useful as a separator or partition in a shipping vessel. Most preferably, the hemicellulose-based adhesive contains one or more bonding agents and water., the hemicellulose being present in an amount of at least 10% by dry basis weight of the bonding agents.
Claims31
A method for preparing a laminate, comprising the steps of
- providing a first laminae and a second laminae, at least said first laminae being liquid pregnable and being impregnated with a liquid adhesive composition said first laminae being in contact with said second laminae along a bonding interface;
- and
- at least substantially dewatering said adhesive to thereby form an adhesive bond between said first and second laminae at said bonding interface, said first laminae comprising a non-woven mat of fibers, said adhesive composition consisting essentially of hemicellulose and water.
A method for preparing a prepreg, comprising the steps of
- providing a liquid pregnable substrate;
- and
- impregnating said substrate with an adhesive composition, said adhesive composition consisting essentially of hemicellulose and water, said substrate comprising a non-woven mat of fibers, said hemicellulose comprising corn hull hemicellulose.
A method for preparing a laminate, comprising the steps of
- providing a first laminae and a second laminae, at least said first laminae being liquid pregnable and being impregnated with a liquid adhesive composition, said adhesive composition consisting essentially of hemicellulose and water, said first laminae being in contact with said second laminae along a bonding interface;
- and
- at least substantially dewatering said adhesive to thereby form an adhesive bond between said first and second laminae at said bonding interface, said first laminae comprising a non-woven mat of fibers, said hemicellulose comprising corn hull hemicellulose.
A method for preparing a prepreg, comprising the steps of:
- providing a liquid pregnable substrate comprising a non-woven mat of glass fibers;
- and
- impregnating said substrate with an adhesive composition, said adhesive composition comprising corn hull hemicellulose and water, said hemicellulose being present in an amount of at least 45% by dry weight of said adhesive composition.
A method for preparing a laminate, comprising the steps of
- providing a first laminae and a second laminae, at least said first laminae comprising a non-woven mat of glass fibers and being liquid pregnable and being impregnated with a liquid adhesive composition, said adhesive composition comprising corn hull hemicellulose and water, the hemicellulose being present in an amount of at least 45% by dry weight of a bonding agent in the adhesive composition, said first laminae being in contact with said second laminae along a bonding interface;
- and
- at least substantially dewatering said adhesive to thereby form an adhesive bond between said first laminae and said second laminae at said bonding interface.
