Thermoplastic bearing materials are being used in automotive transmission architectures where higher pressures and velocities are driving innovation. The benefits thermoplastics offer are high PV capable materials suitable to reduce NVH, increase design freedom while reducing design space, thermal insulation, reduce coefficient of friction, and improve wear resistance when compared to needle bearings. Expanding on the success in automotive may allow for these types of materials to be evaluated in marine lower units, CVT’s, pumps, and other small engine applications

Injection molding is a common molding method for plastic parts and is widely applied to outer parts of motorcycles. To make it stiff enough to hold a large load, glass fibers are usually mixed in it. However, when a plastic part contains glass fibers, the appearance of the outer surface becomes deteriorated after molding. It is because the glass fibers come out of the surfaces. Therefore, the surfaces of these parts are painted to conceal the exposed fibers. Moreover, in the case of glass fiber reinforced plastic made from polypropylene (PP-GF), glass fibers easily come out of the surface and painting is not easily applied. Accordingly, PP-GF hardly satisfies the requirements for outer appearances. In this development, a method that fulfills the appearance requirement and is applicable to mass production was established using rapid heat and cool molding (H&C molding) while eliminating painting process for cost reduction.

Abstract Carbon fiber-reinforced plastic (CFRP) is one of the most commonly used materials in the aerospace industry today. CFRP in pre-impregnated form is an anisotropic material whose properties can be controlled to a high level by the designer. Sometimes, these properties make the material hard to predict with regards to how the geometry affects manufacturing aspects. This paper describes eleven design rules originating from different guidelines that describe geometrical design choices and deals with manufacturability problems that are connected to them, why they are connected and how they can be minimized or avoided. Examples of design choices dealt with in the rules include double curvature shapes, assembly of uncured CFRP components and access for non-destructive testing (NDT). To verify the technical content and ensure practicability, the rules were developed by, inter alia, studying literature and performing case studies at SAAB Aerostructures.
