A method for making a pressure sensitive adhesive comprising: (a) making epoxidized oleic acid, an epoxidized linoleic acid (including fully and partially epoxidized linoleic acid), or an epoxidized linolenic acid (including fully and partially epoxidized linolenic acid) from at least one plant oil, marine oil, other ester of unsaturated fatty acid, or making mixture thereof; and (b) polymerizing the epoxidized oleic acid, the epoxidized linoleic acid, the epoxidized linolenic acid, or the mixture thereof to produce a pressure sensitive adhesive.

Prepregs having a UV curable resin layer located adjacent to a thermally curable resin layer wherein the UV curable resin layer includes at least one UV cured resin portion and at least one UV uncured resin as well as methods for preparing flexible printed circuit boards using the prepregs.

Embodiments of a method to fabricate complex structures include making a pre-cured laminate template. The laminate template is first cured to the required shape, then surface prepared for joining to additional composite lamina. The laminate templates are used to position composite lamina in contact with one another. The composite lamina are then co-cured together to form one monolithic composite structure lacking bond lines or bonded joints. The laminate template supports additional composite lamina for formation of complex structures and replaces template tools from conventional methods.

A composite structure is disclosed having a fiber-reinforce plastic and a wood layer. The wood layer includes an upper surface and a lower surface opposite the upper surface. At least a portion of the lower surface includes at least one engagement feature. A co-cure adhesive layer is applied to the lower surface of the wood layer. The co-cure adhesive layer bonds the fiber-reinforced plastic and the layer. The co-cure adhesive layer comprises at least one elastomer and at least one resin selected from a vinyl ester resin, a polyester resin, and an epoxy resin. The at least one engagement feature may comprise at least one of a groove, a dovetail groove, a curved groove, and a hole.

The teachings herein relate to sound damping materials and particularly to sound damping materials for castings. The sound damping material includes a surface layer including an elastomer and a filler. Preferably the filler includes glass or ceramic beads. The surface layer preferably has a textured surface for contacting with the casting. Preferably the filler has a diameter that provides or contributes to the textured surface. For example, a portion of the filler may have a diameter that is greater than the average thickness of the surface layer. The sound damping material includes one or more metallic layers, preferably for applying a force to a surface of the casting. The sound damping material preferably includes two metallic layers that are separated by a core polymeric layer.

Provided is a building material that is lightweight, exhibits excellent formability, and is inhibited from being damaged during transportation, and a method for producing the same. Specifically, provided is a method for producing a building material, including: a first step of curing a core layer material including a hydraulic material, a silica-containing material, and an aluminum powder, to react the aluminum powder and form bubbles, and incompletely hardening the hydraulic material and the silica-containing material, to form a foamed core layer; a second step of dispersing a surface layer material including a hydraulic material, and a silica-containing material, to form an unfoamed surface layer; a third step of stacking the foamed core layer on the unfoamed surface layer, to form a stack including the unfoamed surface layer and the foamed core layer; and a fourth step of pressing and curing the stack, and a building material produced therewith.

The present invention relates to a laminate for making a molded article comprising: (i) at least one reinforcement Iayer impregnated with a resin matrix; (ii) at least one deployable layer; and (iii) optionally, at least one material comprising at least one non-adhesive side, wherein the deployable layer are compactable, expandable or collapsible including Miura-Ori folds, honeycombs, foams or air mesh. The laminate may be used to form a molded article. The molded articles have uses in biomedical, health care and sport protective devices.

The present invention relates to a method for preparing a continuous carbon fiber-reinforced thermoplastic prepreg, and more specifically, to a method for preparing a continuous carbon fiber-reinforced thermoplastic semi-prepreg or prepreg, comprising the steps of: providing a plurality of carbon fibers having an increased width; preparing a layered product by arranging a thermoplastic film on at least a part of the upper and lower portions of the carbon fibers having an increased width; and preparing a joined product by joining the thermoplastic film and the carbon fibers comprising the layered body.

The present disclosure relates to a method for manufacturing the laminated film that is BSPC (Back Side Printable Clear) and has excellent interlayer adhesion. The method involves a first UV curing step and a second UV curing step and the laminated film includes a transparent film layer, a UV curable ink layer, and an adhesive layer. The first UV curing step includes disposing the UV curable ink layer on the transparent film layer and partially curing the UV curable ink layer by performing a first UV irradiation. The second UV curing step includes disposing the adhesive layer on a surface of the UV curable ink layer opposite the transparent film layer, and further curing the UV curable ink layer by performing a second UV irradiation.
