Abstract:
In the present invention, an injection molded body comprises a fiber reinforced thermoplastic resin composition formed by combining fibrous filler with thermoplastic resin so that the weight average fiber length in the injection molded body is 300 µm or more, and the injection molded body has a skin layer, a core layer and a skin layer in this order in the thickness direction. The injection molded body and a method for producing the same are characterized in that the thickness of the core layer, in which the primary orientation direction of the fibrous filler is 40° or less when the direction perpendicular to the flow direction of the resin composition at the time of injection molding is set at 0°, is 20% or less relatively to the thickness of the injection molded body. The anisotropy of the strength within the molded product is low, making it possible to obtain a molded product with extremely low warping.
Abstract:
A net-shaped composite plenum housing body for a differential assembly having a pump is disclosed. The plenum housing body can include a low pressure inlet and a high pressure outlet configured to receive a control valve. The plenum housing body can also define a fluid inlet channel in fluid communication with the low pressure inlet via a first internal port and can be configured to be in fluid communication with an inlet side of the pump when the plenum housing body is assembled onto the differential assembly. The plenum housing body can also define a fluid outlet channel in fluid communication with the high pressure outlet via a second internal port and can be configured to be in fluid communication with an outlet side of the pump when the plenum housing body is assembled onto the differential assembly. The plenum housing body can also be formed as a net-shape fiber reinforced plastic material including chopped fibers, for example, chopped fiberglass fibers, and an epoxy resin.
Abstract:
A molding material comprising the following components (A) to (D) at the following ratios, in which the component (D) is bonded to a composite comprising the components (A) to (C) and the order in the weight average molecular weight is component (D) > component (B) > component (C) ; (A) 1 to 75 wt% of a reinforcing fiber bundle; (B) 0.01 to 10 wt% of a first propylene-based resin;(C) 0.01 to 10 wt% of a second propylene-based resin having carboxylate groups bound to the polymer chains thereof; and (D) 5 to 98.98 wt% of a third propylene-based resin (first aspect). A resin-adhered reinforcing fiber bundle, wherein a mixture comprising a first propylene-based resin (B) and a second propylene-based resin (C) is adhered to a reinforcing fiber bundle (A); the weight average molecular weight of the first propylene-based resin (B) is larger than the weight average molecular weight of the second propylene-based resin (C); the second propylene-based resin (C) is a propylene-based resin having carboxylate groups bound to the polymer chains thereof; the adhered amount of the mixture comprising the first propylene-based resin (B) and the second propylene-based resin (C) is in a range from 0.1 to 30 parts by weight per 100 parts by weight of the reinforcing fiber bundle (A) ; and the content of the second propylene-based resin (C) is 0.3 to 45 parts by weight per 100 parts by weight of the first propylene-based resin (B) (second aspect). A molding material of this invention provides a long fiber-reinforced thermoplastic resin molding material containing a propylene-based resin as the matrix resin, which allows the reinforcing fibers to be well dispersed into the molded article produced at the time of injection molding and allows the molded article produced to have excellent mechanical properties (first aspect). A resin-adhered reinforcing fiber bundle of this invention provides a resin-adhered reinforcing fiber bundle excellent in the adhesiveness between the matrix resin comprising a thermoplastic resin, particularly a polyolefin-based matrix resin and reinforcing fibers, and good in handling properties (second aspect).
Abstract:
A hollow molded article is obtained by molding a thermoplastic polyester composition comprising a blend of reinforcing fiber glass, polybutylene terephthalate with a melting point of 210 to 230° C. and polyethylene terephthalate with a melting point of 240 to 260° C., wherein at least 10% of the outer surface of the article has a continuous glossy region with a gloss of at least 75 gloss units, as measured at 60 degrees in accordance with ASTM D523 and wherein the gloss varies from the average less than 10 gloss units in the glossy region.

Abstract:
A reduced cost interconnection for shaving razor cartridges. A base member is injection molded as a single continuous mass. The base member defines at least one void that may receive a mass increasing member. The base member has a handle portion integrally formed with a living hinge and an interconnection feature. The interconnection feature is biased to detachably engage a counterpart interconnection feature of a blade cartridge. Elastomeric reinforcement in over molded onto the base member to improve the structural integrity of the living hinge.
