Abstract:

In this study a controllable compression moulding process has been developed for the manufacturing of variable thickness polyurethane heart valves. An experimental facility was established for the compression moulding process. Additive manufactured polymer moulds (AM) were used to determine the suitable design configuration and test process parameters for the successful manufacturing of polyurethane heart valves. Experiments were carried out with a polyurethane solution (PC3595A-B20 and PC3595A) and solvents (N, N-Dimethylacetamide and Tetrahydrofuran) to investigate the effect of changing com

Abstract The present work investigates the compressive properties of SBCF/PA12 commingled unidirectional composites manufactured by the hot compression moulding technique. Different forms of failure mechanism have been observed microscopically for different laminate thicknesses (6, 8, 10, and 12 layers). In addition, fibre-length distribution curves have been developed at failure points. Thus, failure explanations for the SBCF/PA 12 composite during the compression test could be developed, depending upon microscopic observations. Moreover, the effect of laminate thicknesses on compressive beha

Abstract:

Three-dimensional (3D) printing has been successfully applied for the fabrication of polymer components ranging from prototypes to final products. An issue, however, is that the resulting 3D printed parts exhibit inferior mechanical performance to parts fabricated using conventional polymer processing technologies, such as compression moulding. The addition of fibres and other materials into the polymer matrix to form a composite can yield a significant enhancement in the structural strength of printed polymer parts. This review focuses on the enhanced mechanical performance obtained through t

Binder Jetting is an Additive manufacturing (AM) technique in which binding liquid is jetted on layers of powdered materials, selectively according to the Computer Aided Design (CAD) model to form a 3D part. One of the applications of binder jetting technology is the manufacturing of sand moulds for sand casting known as Rapid Sand Casting. Silica sand is often used in both Rapid Sand Casting and traditional moulding due to its good refractory properties coupled with its low cost. However, the use of silica sand is associated with some technical limitations, including its high thermal linear e

However, it is noted that discontinuous natural fibre reinforcement yields negative or negligible improvement in the strength and modulus of FDM-based biocomposites. Hence, an attempt to hy
