摘要:
The assembly consists of at least one metal insert and one reinforcing sheet. The reinforcing sheet contains reinforcing fibers longer than or equal in length to one centimeter. The metal insert comprises protrusions shaped to traverse the sheet, passing between the reinforcing fibers, and to fold by plastic deformation, enclosing the reinforcing fibers when said protrusions are subjected to a longitudinal compression force.

Process for manufacturing a plastic fuel tank (FT) equipped with an internal accessory, by molding a parison using a mold comprising two cavities and a core, said process comprising the following steps: the parison is introduced into the mold cavities; the core is introduced inside the parison, the core having first been fitted with the accessory; the mold is closed so that the cavities come into leaktight contact with the core; the parison is pressed against the cavities by blowing through the core and/or applying a vacuum behind the cavities; the accessory is fastened to the parison by snap riveting using a device attached to the core; the mold is opened to withdraw the core; and the final molding of the parison is carried out by blow molding and/or thermoforming. The accessory comprises an orifice for the snap riveting and at least one protuberance which, during the fastening of the accessory by snap riveting, will at least partially melt to form a local weld which is at another location than the obtained rivet to obtain two different attachment points.

Embodiments provide systems and methods for manufacturing a multilayer golf ball having strong inter-layer bonding and desired structural characteristics, provided by including temporary, removable particles in a golf ball substrate and then removing the particles to form voids in the substrate, including the outer surface and interior of the substrate. Golf balls having the resulting strong inter-layer bonding and structural characteristics are also disclosed.
摘要:
The present invention provides a method of producing a molded article, which can be perform the continuous processes and effectively impregnate a modifying material such as metal complexes in the thermoplastic resin for short period of time. The above object is achieved by providing the method of producing the thermoplastic resin molded article which includes impregnating the high-pressure fluid having a modifying material dissolved therein, in thermoplastic resin, and continuously molding the thermoplastic resin in which the modifying material has been impregnated, into the form of a film.
摘要:
A bend stiffener, and a method of producing the same, comprising an elongated cylinder of a polymer material, having a termination interface (4) on at least one end. An internal reinforcement matrix is provided comprising a first layer of a cylindrically arranged woven material (2). The material of the first layer is unwoven at the termination end, the unwoven fibers engage the termination member (3) and pass back over the first layer. The returning fibers of the second layer may be cut at a plurality of lengths to provide zones (10, 11, 12) of decreasing fiber density from the termination end.
摘要:
The present invention relates generally to composite materials and to methods of manufacturing the composite materials. In particular, the composite material of the present invention utilizes combinations of continuous fibers in the form of loops, chopped fibers, woven fibers and foams.
摘要:
A casing for a writing instrument comprises an outer shaft, an inner shaft, and a nib. The outer shaft is formed using dual injection molding. An outer surface of the outer shaft includes a raised hard part and a raised soft part. The inner shaft is formed of a thin-wall tube having an upper end and a lower end, the inner shaft being configured for insertion inside the outer shaft. The inner shaft further includes a fastener protruding on its upper end that engages an upper end of the outer shaft. The nib is configured to engage the lower end of the inner shaft to help secure the inner shaft within the outer shaft. The raised hard or soft parts on the outer surface of the outer shaft may include an oblique loop-shaped part, a strip-shaped part, and/or an arc-shaped part.
