摘要:
Two composite laminates are joined together by a bondline (22) having portions exposed to the ambient environment. The bondline contains scrim (32) having an electrical conductivity and impedance matched to that of the laminates in order to mitigate effects of lightning strikes.

According to one embodiment, a composite material molding jig (1) includes a rigid portion (2) and a convex portion (3) for forming a groove (70) for inserting an optical fiber sensor (10). The rigid portion (2) has a surface for laminating prepreg sheets (S1, S2). The convex portion (3) is formed in a surface side (2A) of the rigid portion (2). Further, according to one embodiment, a composite material molding method is a method for molding a composite material (30, 40), on which the groove (70) for inserting the optical fiber sensor (10) has been formed, by heating and curing a laminated body (20) of the prepreg sheets (S1, S2) laminated on the above-mentioned composite material molding jig (1).

Described are methods of making a paint roller using an adhesive made from a compound of polypropylene and calcium carbonate having between 5% and 66% calcium carbonate by weight. Described are methods of making a paint roller using preformed strips or core material made from a compound of polypropylene and calcium carbonate having between 5% and 66% calcium carbonate by weight. Described are methods of making a paint roller using a composite cover material made from a compound of polypropylene and calcium carbonate having between 5% and 50% calcium carbonate by weight. One or various compounds may be used to form portions of one or multiple components that make up the paint roller, including, for example, the thermoplastic strips, adhesives and/or the backing of a composite cover material. The materials can be assembled in a continuous manufacturing process.

摘要:
A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by laser welding is provided with a monolithic connector body with a bore. A sidewall of the bore is provided with an inward annular projection angled toward a cable end of the bore. A sidewall of the inward annular projection and the sidewall of the bore form an annular laser groove open to a cable end of the bore. The annular laser groove is dimensioned with a taper at a connector end of the laser groove less than a thickness of a leading end of the outer conductor. The taper provides an annular material chamber between the leading end of the outer conductor, when seated in the laser groove, and the connector end of the laser groove.
