Fiber-reinforced plastic is attractive as a material that can replace metal. It has been widely used in various engineering fields involving aircraft, ships, and automobiles. Currently, personal safety is an important automobile issue. Improvements in pedestrian safety technology, particularly, are required in order to improve vehicles' impact-absorbing performance. In this study, materials with good impact properties that are lightweight and easy to design with will be considered. In other words, a composite is required that has high toughness and high fracture energy while not being brittle. A method for evaluating the compressive strength after impact using a compression after impact (CAI) test has been adopted. New hybrid FRPs that are lightweight and have good impact properties can now be developed.

Carbon Fiber Reinforced

The article presents the results of studies of carbon fiber reinforced plastic VS-51/VTkU-2.200. The influence of the thickness of the specimens and the size of working gage on the compressive strength of carbon fiber reinforced plastic specimens was evaluated; tests were done in accordance with different standards. The results of compression strength tests at high temperature (300–320°С) are given: carbon fiber reinforced plastic VS-51/VTkU-2.200 shows high heat resistance and keeps compressive strength at high temperature tests. Carbon fiber reinforced plastic VS-51/VTkU-2.200 is of increasing interest for application in aircraft structural parts requiring high temperature resistance.

The Impact

Carbon fiber reinforced aluminum layer laminate (CARALL), which were consisted of various numbers of CFRP prepregs, adhesive films and aluminum sheets, were fabricated by an autoclave. Impact damage behaviors of carbon fiber reinforced plastic (CFRP) and CARALL were investigated. The impact damage resistance of CARALL was significantly higher than that of CFRP. Compression after impact (CAI) tests was conducted to investigate the effect of impact damage on the compression strength of CARALL and CFRP specimens. The CAI strength of CFRP and CARALL decreased with increase of impact energy. However, CAI strength of CARALL is higher than that of CFRP, which can be attributed to the excellent impact damage absorbability of aluminum sheet in CARALL.

Nowadays, how to deal with fiber reinforced plastic (FRP) residue becomes very difficult. In this paper, the characteristic of the production technology of epoxy based artificial granite was considered. Epoxy resin, FRP residue, granites and fillers were used on the study of adding FRP residue and epoxy based artificial granites of different proportion were prepared. They were prepared by casting moulding under the normal pressure and temperature. Flexural and compressive strength of the artificial granites were studied. SEM was used to observe the internal microstructure of artificial granites. Meanwhile, effects of different granularity and content of FRP residue on the properties of artificial granites were discussed.
