FIBER-REINFORCED RESIN MEMBER AND METHOD FOR PRODUCING FIBER-REINFORCED RESIN MEMBER
A fiber-reinforced resin member is provided in which a non-conductive sleeve and first and second non-conductive sheets are disposed between a metal fastening member and CFRP laminate, electrical continuity between the metal fastening member and the CFRP laminate is cut off, and corrosion of the metal fastening member due to galvanic corrosion is prevented. A first annular space is formed between a first flange portion of a first member and the first non-conductive sheet, a second annular space is formed between a second flange portion of a second member and the second non-conductive sheet. Therefore, even if frayed carbon fiber sticks out from a gap between the non-conductive sleeve and the first and second non-conductive sheets, due to the first and second annular spaces being formed therein, it is possible to prevent the sticking-out carbon fiber from contacting the first and second members and providing electrical continuity.

Medical cap and a producing method thereof
In the medical cap comprising a plug 10 made of thermoplastic elastomer and an outer frame 20 made of synthetic resin, the side surface part of the plug is contacted with an inner wall 211 of the side circuit part of the outer frame in a non-fused state and is held in a state with pressure applied from the leg part of the outer frame 22. As a result, the wetted surface of the plug is not flat shaped but has an inclination downward to the circle center. Protrusion 14 can also be provided on the wetted surface and in such a case, the bottom part of the protrusion part that is one part of the wetted surface has an inclination downward to the circle center.

System and method for minimizing wrinkles in composites
A wrinkle mitigation system may include at least one tooling rod disposed against a tool surface at a location on the tool where a composite ply is configured to overlap the tooling rod. The tooling rod may have an elongated shape and may be generally oriented along a direction of wrinkle formation in the composite ply. The tooling rod may have a rod width that results in the composite ply assuming a corrugated shape when compaction pressure is applied to the composite ply.
Method of making a fiber reinforced energetic composite
A method of making a fiber reinforced energetic composite is provided. The method includes providing a mold or mandrel defining a shape for the fiber reinforced energetic composite, providing an impregnated fiber layup over the mold or mandrel, and curing the impregnated fiber layup. The impregnated fiber layup includes a fiber layup and polymer resin, the fiber layup formed from a plurality of reinforcing fiber layers and an energetic polymer nanocomposite disposed adjacent one or more of the reinforcing fiber layers with the polymer resin impregnated within the reinforcing fiber layers. The energetic polymer nanocomposite includes core-shell nanoparticles entrained in a thermoplastic polymer matrix where the core-shell nanoparticles include a core made of metal and at least one shell layer made of metal oxide disposed on the core or a core made of metal oxide and at least one shell layer made of metal disposed on the core.

THERMOPLASTIC POLYMER COMPOSITION AND MOLDED ARTICLE
The present invention is a thermoplastic polymer composition which contains 10-120 parts by mass of a polar group-containing polypropylene resin (B) per 100 parts by mass of a thermoplastic elastomer (A) that is a block copolymer having a polymer block containing an aromatic vinyl compound unit and a polymer block composed of a conjugated diene unit having 40% by mole or more of 1,2-bonds and 3,4-bonds in total, or a hydrogenated product of the block copolymer (provided that a thermoplastic polymer composition containing 1 part by mass or more of a polyvinyl acetal resin is excluded). This thermoplastic polymer composition is able to be bonded with a ceramic, a metal or a synthetic resin without requiring a primer treatment, and has excellent flexibility, mechanical characteristics, moldability, heat resistance and storage stability.
METHOD FOR MANUFACTURING A REINFORCED PART COMPRISING A COMPOSITE MATERIAL
Method for manufacturing a reinforced part, including the steps of: producing a support structure and then covering the support structure, at least partially, with at least one composite material including reinforcement fibres, with local adhesion of the support structure and/or the composite material, during positioning thereof, to ensure its retention on the support structure, the support structure being an integral part of the reinforcing part.
