Abstract: Example approaches are disclosed for manufacturing composite or fiber reinforcement preforms. Liquid, fibrous, binding and potentially other materials are mixed into a composite mixture slurry in a slurry container. A porous tool having a specific porous outer surface portion approximating a specific exterior surface portion of a spatial shape of a final product is immersed in the slurry container. A suction pressure is applied to draw a portion of the fibrous material intermixed with a corresponding portion of the binding material in the slurry onto the specific outer surface portion. The porous tool attached with the wet preform is removed from the slurry container. The wet preform is partially dried into a partially dried preform attached to the porous tool. The partially dried preform is dried, solidified and/or consolidated and/or injected with a resin and cured into a solid composite preform of the spatial shape of the final product.

Abstract: A solid lignocellulosic bioplastic can be formed from a biomass comprising an intertwined structure of lignin, hemi-cellulose, and cellulose. The lignin in the biomass can be dissolved such that the cellulose is fibrillated. After the lignin dissolution and cellulose fibrillation, the lignin can be regenerated in situ. The regenerated lignin can be deposited on and can form hydrogen bonds between the fibrillated cellulose, so as to form a slurry of lignin-cellulose solids in solution. The slurry can then be dried to form the bioplastic. In some embodiments, the lignin is dissolved by immersing the biomass in a first chemical. The lignin can then be regenerated in situ by addition of a second chemical to the first chemical.

Abstract: The invention is inspired by the animal bone structure which is normally hollow in the middle. The invention introduces a novel foam article and a method of manufacturing it to include cavities similar to the bone structure. The novel foam article comprises a cavity-defining structure that is placed inside a mould prior to introducing expanded polymer beads into the mould. The cavity-defining structure comprises hollow compartments or layers that create macro-cavities and hollow compartments in specific sizes and locations of the foam article during the moulding process. As a result, the foam article equipped with the cavity-defining structure uses fewer polymer beads and is lighter than foam articles made conventionally. The invention also improves the foam article in terms of its shock absorption, durability, thermal insulation, acoustic insulation, and floatation.
