3D printing of reinforced polymeric materials, which provides products excellent physical and mechanical properties, is at the forefront interest in field additive technologies. To ensure material, time, financial savings, objects having reduced filling density are frequently prepared. The presented work aims to study effect different levels (18, 42, 62% using a honeycomb pattern) contrast 100% solid fill carbon fiber-reinforced polyamide 6.6 materials processed by Fused Filament Fabrication...
Abstract Rigid polyurethane (PUR) foams are widely used as heat insulation material in construction industry or for electronic appliances manufacturing. After finishing their life‐time, it is necessary to eliminate foam wastes. The aim of this study was prepare a pair industrial PUR adhesives medium viscosity containing recycled rigid foam. Three methods milling were tested: knife‐milling, two‐roll milling, and ball‐milling. Only gives the micro‐powder usable following modification. passive...
3D printing, also known as additive manufacturing, is becoming increasingly popular for prototype processing in industrial practice. Laser sintering, which a laser powder bed fusion technique, versatile and common printing technology, enables compact high-quality products. Polyamide 12, material, provides reliable mechanical thermal properties. Weaknesses applying this technology polyamide 12 include incomplete information regarding the application of various types additives different...
The aim of this paper was to analyze selected properties beech wood (Fagus sylvatica L.) treated by one-sided surface charring. Specimens were one-side charred with a hot plate using several time-temperature combinations (from 200 400 °C). Characteristics such as colour, discoloration, roughness, fire resistance, total carbohydrate content at layers and decay resistance evaluated. Surface charring applied the radial tangential surfaces. Colour measurements showed that turned grey due In...
Rigid polyurethane (PUR) foam is products used as a biomedical material for medical device testing. Thermal stability very important parameter evaluating the feasibility of use testing surgical instrument load during drilling. This work aimed to perform experimental measurements determine dependence mechanical properties certified PUR on temperature, strain rate and density. Experimental were realised three types samples with different density 10, 25 40 pounds per cubic foot. The...
Plastics represent an integral part of our everyday lives, with various functions from packaging materials to insulation layers in buildings. Pure expanded polystyrene (EPS) is a good example fully recyclable material. However, once polluted other or substances, EPS becomes serious environmental burden. In this work, waste for the production greener building composites balanced properties and utility value was investigated. Natural aggregate (2/4 mm) substituted corresponding fractions...
Purpose The purpose of this paper is to clarify the relationship between use different polymer matrices for preparation composite materials, namely, polyethylene terephthalate-glycol (PET-G) and polyamide (PA), using Composite Fiber Co-Extrusion technology with application two types carbon fibers, short continuous. aim study also extend knowledge production materials a defined structure from point view their influence on microstructure physical-mechanical properties....
The time-evolution of dynamics as well microstructure and mechanical response phosphate-based geopolymers was probed using x-ray photon correlation spectroscopy rheological tests. analyzed relaxation processes in the freshly prepared geopolymer mixes evidenced a q-independent mode autocorrelation function, ascribed to density fluctuations already established molecular network, undergoing reconfiguration without significant mass transport. Upon curing, detected motions are localized depict...
Biomass residues from the agricultural industry, logging and wood processing activities have become a valuable fuel source. If processed under pyrolysis combustion, several products are generated. Bio-oil gases essential alternatives to fossil coal-based fuels for energy electricity production, whose need is constantly growing. Biochar, porous carbon-based lightweight product, often ends up as soil fertilizer. However, it can be applied in other industrial sectors, e.g., plastics production...
Common latex coatings suffer from poor water resistance, which often limits their practical application. This paper reports on the preparation of polyacrylate latexes using various approaches to tune wettability, and surface properties coating films. The mutual effects fluorinated monomer copolymerization, emulsifier type (polymerizable general), intra- or interparticle covalent crosslinking (due allyl methacrylate copolymerization a keto-hydrazide reaction, respectively) were studied....
Epoxy resins are characterized by excellent properties such as chemical resistance, shape stability, hardness and heat but they present low flame resistance. In this work, the synthesized derivatives, namely hexacyclohexylamino-cyclotriphosphazene (HCACTP) novel diaminotetracyclohexylamino-cyclotriphosphazene (DTCATP), were applied curing agents for halogen-free retarding epoxy materials. The thermal combustion behavior of cured investigated. obtained results revealed that application both...
