System Level Design Simulation to Predict Passive Safety Performance for CFRP Automotive Structures

Design, development and analysis of a full carbon fibre reinforced composite chassis of an electric vehicle

“…These findings strongly indicate the likely reasons why the application of carbon composite in vehicle structures is limited to non-crash energy absorption, which correspond to the findings by Lescheticky from BMW [86]. BMW is currently exploring the correlation of composite simulation to expand carbon composite application into the area outside of the safety cell particularly in crash absorption structure [86]. As a result of the findings, a reasonable approach for EVA was to develop metallic crash structure and the details of the development will be covered in Section 4.5.…”

“…Even with all the benefits of composite crash structure, compromise for less ideal, simpler solutions has to be explored. These findings strongly indicate the likely reasons why the application of carbon composite in vehicle structures is limited to non-crash energy absorption, which correspond to the findings by Lescheticky from BMW [86]. BMW is currently exploring the correlation of composite simulation to expand carbon composite application into the area outside of the safety cell particularly in crash absorption structure [86].…”

Study of Monitoring Method and Melt Flow Behavior in Compression Molding Process Using Thermoplastic Sheets Reinforced with Discontinuous Long-Fibers

“…In the automotive industry, lighter materials such as glass-fiber-reinforced plastics and carbon-fiber-reinforced plastics have been applied to vehicle parts for improvement of fuel efficiency. Currently, vehicle parts made from fiber-reinforced plastics (FRP) with excellent specific strength, specific rigidity, and good moldability are also being constantly developed, e.g., [1][2][3][4][5][6][7][8][9][10]. In the case of the mass production of parts reinforced with discontinuous long fibers more than 10 mm long, a compression molding method using sheet-shaped fiber-reinforced thermoplastics is generally applied.…”

An innovative fixture for testing the crashworthiness of composite materials

“…It consists of an experimental setup similar to that of Feraboli, but with the addition of some features able to induce other failure modes in the specimen (such as tearing) if desired. Engenuity worked as well on the simulation software to predict the crush behavior of structures, getting good agreement with experimental tests [21]. The Engenuity's fixture was successfully used under dynamic and impact load [22].…”

“…A relation was found between curvature and specific energy absorption [20]. An interesting progress in the field of crashworthiness of composite materials has been proposed by the company Engenuity [21]. It consists of an experimental setup similar to that of Feraboli, but with the addition of some features able to induce other failure modes in the specimen (such as tearing) if desired.…”
