A method for bonding thermoplastic fiber-composite parts comprises providing surface texture on one or both parts being bonded, and/or providing both parts with engagement features. Such surface textures and engagement features have a specific geometry and fiber alignment that facilitate fibrous interlock between the two parts at a bonding interface via in-situ consolidation.

A method for covering a roof, the method comprising (i) providing first and second silicone membranes, where the membranes are in the form of rolls; (ii) unrolling the first and second silicone membranes over a roof surface; (iii) positioning first and second membranes adjacent to one another and overlapping and edge of the second over an adjacent edge of the first membrane to thereby form a lap; (iv) securing the first and second membranes to the roof surface; and (v) seaming the first membrane to the second membrane in the lap.

Disclosed is a resin composite having improved tensile properties and a method of preparing the same. Particularly, the resin composite comprises a matrix resin and a reinforcement resin which are made of thermoplastic resin compositions.

A molding apparatus that adsorbs thermoplastic resin extruded in a sheet form from an extruding machine, onto a cavity of a mold, and shapes the thermoplastic resin into a shape according to the cavity is provided. The molding apparatus may include a frame that is positioned on a periphery of the mold and is movable relative to the mold, wherein a suction part for suctioning the thermoplastic resin is provided in a contact surface of the frame to contact the thermoplastic resin, and the suction part is provided in a linear shape along with a longitudinal direction of the frame positioned on the periphery of the mold.

A method for surface preparation of a composite substrate prior to adhesive bonding. The surface preparation method includes applying a resin-containing peel ply onto a composite substrate, followed by co-curing. The resin-containing peel ply contains a non-removable textile carrier and a removable woven fabric embedded therein. After co-curing, the peel ply is removed from the composite substrate such that the removable woven fabric is removed but the non-removable textile carrier and a film of residual resin remain on the composite substrate, thereby creating a modified, bondable surface on the composite substrate. The composite substrate with the modified surface can be bonded to another composite substrate, whereby the textile carrier remains an integrated part of the final bonded structure.

The present invention relates to a molding substrate capable of realizing an exterior material for a vehicle from which the attached snow or ice is more easily peeled off. As a result of continuing studies by the applicant of the present application, it has been found that the problem that the adhered snow and ice hardly peels off, which occurs on a molding base material provided with a fiber base layer containing a core-sheath type conjugate fiber in which the sheath portion is a polypropylene-based resin and the core portion is a polyester-based resin, can be solved by adjusting the mass percentage of the core-sheath type conjugate fiber occupying the fiber constituting the fiber base material layer. Specifically, the present inventors have provided a molding substrate which can realize an exterior material such as an exterior material for a vehicle from which adhered snow or ice is easily peeled off, by being a molding substrate having a fiber base layer having a mass percentage of more than 70% by mass.

A method of manufacturing a composite part comprising a core and at least one skin region formed of a low friction UHMWPE skin polymer attached thereto, by: a) providing a mold with a heatable mold cavity; b) loading into the mold cavity UHMWPE powder followed by a core element having a surface with at least one contacting region provided with a plurality of anchoring sites, loading onto the core element, a layer of UHMWPE in powder form adjacent the contacting region, and applying a heat pressing step to melt the skin polymer powder to form a molten skin polymer matrix, and cooling to solidify the skin polymer matrix forming a skin region mechanically engaged into anchoring sites of the core element.

A method of producing a reinforcing bar (rebar) includes: arranging one or more thermoplastic polymer fibers (2) in a central portion of a cross-section; arranging a plurality of non-metallic reinforcing fibers (1) on an outer periphery of the thermoplastic polymer fiber(s) (2); heating the thermoplastic polymer fiber(s) (2) to its (their) melting temperature or higher to melt the thermoplastic polymer fiber(s) (2); and cooling the melted thermoplastic polymer to form a bar-shaped polymer layer (91) in the central portion of the cross-section and a fiber-reinforced polymer layer (92) on an outer periphery of the bar-shaped polymer layer (91).
