The effective parameters that influence in situ cast ferroTic composites were investigated. Centrifugal casting of specimens was carried out using ceramic & metallic molds. OM, SEM and XRD techniques were used to examine the existence of flows in the specimens. Results show that the control of chemical composition, processing, cooling rate and heat treatment has &#10a promising effect on the qu...

Synopsis: This article reviews the recent advances in the research of Engineered Cementitious Composites (ECC), a class of microstructurally tailored fiber reinforced cementitious composites. The design basis, the processing routes, and some ECC performance characteristics in structural applications are highlighted. This article is dedicated to Professor Surendra Shah, in honor of his seminal c...

The article deals with genetic algorithms and their application in face identification. The purpose of the research is to develop a free and open-source facial composite system using evolutionary algorithms, primarily processes of selection and breeding. The initial testing proved higher quality of the final composites and massive reduction in the composites processing time. System requirements...

The application of thermoplastic polymers as a matrix material in fibre reinforced composites has grown steadily over the last decades [1]. Thermoplastic composites offer clear advantages over their thermoset counterparts in terms of improved fracture toughness, potential for recycling and, most notably, the possibility to reshape the product at higher temperatures [1,2]. The latter allows rapi...

An advanced SiO2–lignin hybrid material was obtained and tested as a novel poly(vinyl chloride) (PVC) filler. The processing of compounds of poly(vinyl chloride) in the form of a dry blend with silica–lignin hybrid material and, separately, with the two components from which that material was prepared, was performed in a Brabender mixing chamber. An analysis was made of processing (mass melt fl...

Composites with a bulk metallic glass matrix were synthesized and characterized. This was made possible by the recent development of bulk metallic glasses that exhibit high resistance to crystallization in the undercooled liquid state. In this letter, experimental methods for processing metallic glass composites are introduced. Three different bulk metallic glass forming alloys were used as the...

The evolution of the thermal conductivities of the unidirectional, 2D woven and 3D braided composites during the CVI (chemical vapor infiltration) process have been numerically studied by the finite element method. The results show that the dual-scale pores play an important role in the thermal conduction of the CVI-densified composites. According to our results, two thermal conductivity models...
