A method and a system for fatigue life prediction of additive manufactured components accounting for localized material properties. The method and the system is employed for prediction of fatigue life properties of an additive manufactured element, with a data collection step in which several data points for maximum stress vs. cycles to failure for different given processing steps of the element are collected, with a training step in which a Machine Learning system is trained with the collected data, and with an evaluation step in which the trained Machine Learning system is confronted with actual processing steps and used to predict the fatigue life properties of the element.

Provided are a hose excelling in a lightweight property and in fatigue fracture resistance, a method for manufacturing the hose, and a hydraulic pump. The hose includes a tube, an interior of the tube being hollow, continuous carbon fibers and/or continuous glass fibers wound around an outer circumference of the tube, and a thermosetting resin present external to the tube. The thermosetting resin has an elastic modulus from 0.5 to 10 MPa, and the continuous carbon fibers and/or continuous glass fibers are impregnated with at least a part of the thermosetting resin. The elastic modulus of the thermosetting resin is a numeric value determined by: heating the thermosetting resin for 2 hours at a curing temperature of the thermosetting resin; then subjecting the thermosetting resin to thermoregulation for two weeks under a condition of a temperature of 23° C. and a relative humidity of 55%; and then performing a measurement in accordance with JIS K7161:2019.

An injection molded cap or closure having a weld line, wherein the injection molded cap or closure is formed from an ethylene-based resin comprising a high molecular weight component and a low molecular weight component.

A wrapped V-belt includes: a belt main body containing a compression layer containing a compression rubber layer and a fabric-laminated body layer a tension rubber layer and a tension member buried between the compression layer and the tension rubber layer; and an outside cloth that covers a periphery of the belt main body, in which the compression layer has a plurality of notch portions not covered with the outside cloth, and the notch portion has a top disposed in the fabric-laminated body layer.

A resin composition useful for making an inside door handle with a skin-core structure made by using co-injection, an inside door handle manufactured using the resin composition, and a method for manufacturing such a door handle are provided herein.

A method of rivet bonding a workpiece stack-up that includes one or more polymer composite workpieces, such as carbon fiber composite workpieces, involves several steps. In one step, adhesive is applied to a surface of the workpiece stack-up. In another step, workpiecesincluding the polymer composite workpiece(s)are brought together. In yet another step the adhesive is partially or more cured. A rivet is installed through the workpiece stack-up and through the adhesive in another step. The method strengthens the resulting rivet-bonded joint by minimizing or altogether precluding fracture, cracking, and/or delamination thereat.

A method for manufacturing a flexible composite belt or cable, in the method, one or more parallel reinforced plastic profiles (11) are manufactured by pultrusion, continuous lamination or other continuous method. After surface treatment, the reinforced plastic profiles (11) are guided at a short distance from one another to coating treatment, which is carried out by extrusion or lamination or pultrusion. In the coating treatment, the reinforced plastic profiles are enveloped with a coating material (12) improving wear resistance which joins the reinforced plastic profiles (11) together and forms the coating of a finished belt or cable (10). Finally, the finished belt or cable (10) is wound on a reel.
