In this paper, the mechanical properties of carbon fiber polypropylene composites prepared under various process conditions were investigated. Two different types of polypropylene composites were produced by mixing and compressing the mixtures using hot press. The mixture was prepared by mixing polypropylene with chopped carbon fiber and carbon fiber percentage (wt%) was varied. Mechanical properties investigated were tensile test, impact test, bending test and density test. The Scanning Electron Microscopy (SEM) was employed to study the morphology of the composites. The highest tensile strength was obtained for polypropylene (MFI 60) composites reinforced with 10 wt% carbon fiber. The composite also exhibited the best tensile and flexural properties.

This Research work explains the Mechanical properties of Flexural test, Tensile test, Impact test and SEM analysis of Sansevieria Trifasciata fiber (STF), Carbon fiber (CF) [1] hybrid polymer composites. The Hybrid Composite laminates were created with five different fiber % of STF (0%, 10%, 20%, 30% and 40%) and % of Carbon Fiber (100%, 90%, 80%, 70% and 60%). The manufacturing process was completed by hand layup technique. Mechanical properties of Hybrid Composite laminates were included to Tensile, Flexural and Impact testing. The SEM shows fiber debonding and de-lamination of fiber and resin can be observed. The explanation covers that Flexural, Tensile and Impact quality increases without affecting the extension of the Hybrid Composite with fiber extents

This research paper deals with an investigation of the influence of honeycomb core compression on the mechanical properties of sandwich structures. These structures consist of prepreg facing layers and two different material types of honeycomb and are produced by modified compression molding called Crush-Core technology. Produced structures are mechanically tested in three-point bending test and subjected to low-velocity impact and Charpy impact test.

The Impact

Impact characteristics of Epoxy matrix composites is investigated by impact machine. Four different types of reinforcement are used in the experimental works: type one: 1.9wt% steel fiber, 1.9wt% carbon fiber,1.9 wt% carbon nanotube, 1.9 wt% woven carbon fiber.This work shows that reinforcing epoxy with (1.9 wt% of woven carbon fiber) improves the impact properties where energy, force and deformation values of impact test for this composite were 18.4J, 3580.59 N and 18 mm respectively while for epoxy were 2.927 J, 921.849 N and 18.413 mm respectively.

Abstract European beech (Fagus sylvatica L.) was thermally modified in a closed reactor system under various process conditions. Sorption cycles, dynamic vapor sorption (DVS) measurements, and a three-point bending test were performed on thermally modified wood (TMW) to assess hygroscopicity and mechanical properties. As a function of mass loss (ML), the initial equilibrium moisture content (EMC) measured at 20°C/65% relative humidity (RH) directly after the process was strongly influenced by the RH during the process. This effect is explained by realignments of amorphous polymers in the cell wall ultra-structure in the course of thermal modification (TM). However, the EMC of TMW gradually increased after sorption cycles consisting of conditioning over liquid water and water-soaking. This increase was most distinct for TMW modified at low RH, which is an indication for reversible ultra-structural realignments. Results of the bending test suggest that structural realignments also hindered the plastic flow of amorphous cell wall polymers, thereby reducing inelastic toughness and inelastic deflection, while other bending properties were solely affected by ML alone. Process conditions in a closed reactor systems have a profound impact on resulting wood properties, and thus, the partial reversibility of these property changes need to be considered during the application.

Polymerized cyclic butylene terephthalate (pCBT) resin casts filled with short carbon fibers were prepared by the melt-mixing approach. The electrical conductivity of short-carbon-fiber (SCF) reinforced thermoplastic pCBT resin casts were investigated with a special attention paid to the properties in the percolation threshold region and the mechanical properties of the composites were also studied. The percolation threshold value of the novel material system was determined which was also verified by SEM images and the thermoelectric behavior of the specimens. Even though the electrical properties of SCF/pCBT composites enhanced significantly, the material becomes more brittle than neat pCBT and all the specimens appear brittle fracture during the mechanical test. Moreover, fiber pull-out is the main damage form in three-point-bending test.
