In this paper, the effect of continuous carbon fibers (CCF) on the stiffness of 3D printed frames is investigated. Fused deposition modelling (FDM) technology is employed to build three typical frames with 15% of CCF and 85% poliamide 12 which is combined 10% short carbon fibers (PA12-CF) for compress testing.

In this study, the effect of technological innovation capabilities (R&D capability, technology accumulation capability, technological innovation system) possessed by Korean small and medium-sized enterprises (SMEs) on their competitiveness improvement through innovation performance (product development and process development capabilities) was investigated. As a result of empirical analysis using the questionnaire, it was found that the R&D capability of small and medium-sized manufacturing industries in Korea did not affect product development capability or process development capability.

The main aim of this study is to investigate utilising root-like architectures to improve the interfacial strength of pin-integrated hybrid composite-metal structures. Joints are critical elements in aircraft structures and require special consideration due to their vital role in the structural integrity of airframes. Although bonded and bolted systems are used commonly in engineering applications, pinning technologies have shown tremendous potential for hybrid joints.

While it is recognised that knitted fabrics may have their place in firefighting PPC, especially for undergarments, from the point of view of fire performance, strength and presentation, woven fabric constructions appear to be more suitable for work wear applications. Hence, this study is concerned with developing and testing a range of functional, woven Station Wear fabrics designed to enhance flame protection, durability and thermo-physiological comfort properties. In trying to improve all three aspects, a compromise in the properties of fabrics developed would be very likely.

In Vietnam, currently the study of fuel cells is almost neglected and there is very little fundamental research on this issue. The research on fuel cells of our country is at innitial stage, mainly researching catalytic material in the laboratory and almost has not research in the technology of manufacturing fuel cell (stack).

A gas metal arc welding robot was used to build a thin-walled component made of mild steel on a low-carbon substrate according to the AM principle. Thereafter, the specimens for observing microstructures and mechanical properties were extracted from the built thin-walled component. The microstructures of the specimen were observed by an optical microscope; the hardness was measured by a digital microhardness tester, and the tensile tests were carried out on a tensile test machine.
