The additive manufacturing represents a new production method of composites reinforced with a continuous fibre. In recent times, the material produced by this new manufacturing method constituted a replacement for conventional materials—e.g., steel in many technical areas. As the research on FRTP composites is currently under way, the purpose of th...

The present review paper focuses on the current state of the art of the alumina-silicate ceramics and surface modifications of ceramics dedicated as fillers in composites with carbon fiber. The use of aluminum-silicates in the form of a cenosphere due to their outstanding properties, i.e., low density, high hardness, and total chemical inertness se...
In comparison to other commercial reinforcement fibres, carbon fibres are superior in terms of mechanical properties such as specific tensile strength and specific Young’s modulus. Being used in carbon fibre reinforced polymers they show great potential to reduce moving masses in applications like aerospace, automotive and mechanical engineering. T...

The effect of unidirectional (UD) carbon fibre hybridisation on the tensile properties of flax fibre epoxy composite was investigated. Composites containing different fibre ply orientations were fabricated using vacuum infusion with a symmetrical ply structure of 0/+45/−45/90/90/−45/+45/0. Tensile tests were performed to characterise the tensile pe...

One of the most common defects in carbon fibre reinforced plastics (CFRP) is porosity. Too much of those defects could be serious problems to mechanical properties, which directly take effect on elements safety, like aircrafts. Therefore, the evaluation of porosity is very important test. Microscopic observations are widely used as a quality instru...
Bakalářská práce se zabývá návrhem zařízení na úpravu parametrů svazku uhlíkových vláken navíjecího stroje. Tyto parametry bude zařízení upravovat za normálního provozu navíjecího stroje tak, aby se nemusela snižovat produktivita výroby. Zařízení je navrhováno primárně pro vysokopevnostní uhlíková vlákna (např. T700S 12K). Součástí práce je porovná...

Mid-term clinical and radiological evaluation of a carbon-fiber cage in multilevel cervical spondylosis (MCS). Anterior cervical corpectomy and fusion (ACCF) using titanium mesh cages (TMC) has shown satisfactory outcomes, but with subsidence of up to 20%. Conventional long-fiber carbon fiber cages have shown a safe profile in discectomy/fusion (AC...
A reference lignin separated from an industrial softwood kraft black liquor via an improved LignoBoost process was compared to four other lignins derived from the same liquor. The four lignins were produced by using a) pH-fractionation within the LignoBoost process, b) ultrafiltration of black liquor prior to the LignoBoost process, and c) solvent ...
The fire resistance of lightweight sandwich panels (SW) with carbon fibre/epoxy skins and a poly(methacryl imide) (PMI) foam core is investigated in compression under direct application of a severe flame (heat flux = 200 kW m(-2)). A bench-scale test procedure was used, with the sample held vertically. The epoxy decomposition temperature was quickl...
