“…But one should be noted that for tissue engineering (as well as for all implanted materials), it is permissible to use 100% of synthesized compounds. The active ingredients isolated from amber, which can be purified and approved by pharmacology, can be the basis for their subsequent productions and implementation in blood vessels implant structure [44][45][46].…”

The amber nano fibres are bio-active composites which could be applied in three-dimensional printing. The idea of using the amber for creating a new 3D printing material, including technological composition of the innovative amber nano and micro fibres is based on the hypothesis that organic compounds of succinite have an effective impact on living cells, including reparative, stimulating, for sedative effects as well protective properties from electro-magnetic field. To produce amber nano fibres, bioactive components were used that were isolated from the succinite and tested (in vitro) in the scientific laboratories. Three-dimensional printing is an emerging technology, which has been initially used to design and generate three-dimensional structures mainly for transplantation therapies. This process, which can be used for a variety of polymers, is becoming an increasingly essential component of biotechnological advancements. This article discusses the foundations of this technology, namely the processes used in conventional three-dimensional printing; it also discusses tissue engineering, a discipline of which new implementations of this technology are used as bio printing. The shortcomings of tissue engineering are addressed, including the failure of existing technology to manufacture nanofiber-based constructs used in blood vessels, cartilage, artery valves, tendon, cardiac muscle valves, muscle, and cornea. From this need for nanofiber processing, electrospinning is proposed as a possible roadmap for imminent tissue engineering threedimensional printing technologies, and finally, the latest integration of this technology with three-dimensional printing is addressed, highlighting the existing shortcomings in maintaining mandatory nano resolutions.

“…Nowadays, one of the main engineering challenges is to develop and introduce in the mass production efficient reinforcement material. An example is: innovative reinforcing composite fibre metal-crystalpolymer with protective properties from the electromagnetic field [8], [9]. Short fibres may be the main or the secondary reinforcement (in combination with rebars) bearing the bending moments and the shear stresses.…”

Concrete reinforced by short steel fibres is typical brittle matrix composite, in which fibres are impeding cracks growth, such way increasing material’s tensile strength. The use of steel fibre reinforced concrete (SFRC) in structures with high physical and mechanical characteristics makes possible to reduce their weight and cost, to simplify their production technology, to reduce or eliminate reinforcement labour, at the same time increasing reliability and durability. Randomly distributed discontinuous fibres are bridging the crack’s flanks providing material’s “ductility”- like non-linear behaviour at cracking stage. The current study is focused on one formulation of a specific type of concrete matrix with added fibres and without fibres. Concrete cubes and prisms without fibres and having in every situation the same content of 60 mm long fibres were fabricated. Cubes (100×100×100 mm) were tested in compression and beams (100×100×400 mm prisms) were tested under four-point bending (4PBT). Fracture process (crack growth) in the material was modelled, based on experimental results (part of experimental data was used). Finite element method (FEM) using the ANSYS program analysis were realized modelling stress distributions in the broken beams with the goal to predict fracture process. Model’s prediction was validated.

“…Back in the days of the Roman Empire, concrete made a real revolution in construction [2], [3]. Since then, concrete has been reinforced in various ways and materials, for example: bars made of different materials [4]- [7], different short fibres [8]- [10], and using different technologies [11]- [14]. The addition of discrete fibers to the concrete mixture to enhance its toughness and tensile strength is well acknowledged.…”

Different authors conducted studies on fiber reinforced concretes (FRC) with carbon fibres of different lengths and some results showed that concrete mix with homogeneously distributed short fibres in their volume have good strength and ultra-strain compared to normal plain concrete mix. However, this study is focused more on 3-dimensional (3D) carbon fibre reinforced plastic (epoxy) CFRP composite thin rods frame used as a reinforcement in concrete which shows good increase in loadbearing and ductility. Were investigated concrete mixes with superplasticizer, nano-silica, quartz sand, fine natural sand and gravels. Diagonal cross bracing carbon fibre epoxy frames were used as a reinforcement giving better ductility results. Proposed study approach is to show that the reinforced concrete with provided materials have an increased performance in terms of ductility, sustainability, and load bearing in cracked statement. Total, four groups of concrete and each group with three beams were casted and tested in this experiment, three groups with three different shapes of carbon frames and three beams without frames to compare the mechanical properties after 28 days. Failure mechanisms in any particular case were analysed.
