Title: Degradation of E-glass fiber mechanical properties during composite sheet molding compound production for automotive applications

Abstract

Research into pyrolysis-based recycling of sheet molding compounds (SMCs) to recover glass fiber for reuse has indicated significant pre-existing tensile strength damage in the shredded recycling input materials. Here, this loss in mechanical durability inherently hurts the value proposition of recycled glass fiber by limiting reuse of the fiber for reinforcement. In this study, the mechanical properties of glass fibers at each step in the first lifecycle of an SMC material are measured to assess the extent of cumulating fiber damage prior to recycling and identify potential causes of this degradation to maximum fiber tensile performance.

Recovery of glass fiber reinforcement from retired wind turbine blades for recycled composite materials

Technical Report Li, Luyue ; Benson, Bowie Jade

Currently wind turbine blades use glass fiber reinforced resins, which have a specified lifespan before they are deemed unfit for operation. At the end of their useful lifetime, the structure is heavily compromised, unlikely to be refurbished or repurposed for anything. The resin matrix in the blade can be pyrolyzed, leaving behind the glass fibers for reuse. However, conventional pyrolysis processing compromises the glass fibers’ strength (ergo usefulness) while depositing char and other decomposition products on the fiber surface. This makes reusing glass fibers uneconomical since there is no market for burnt, weakened, dirty fiber. Carbon Rivers INC. is developingmore »« less
Recycling of Commercial E-glass Reinforced Thermoset Composites via Two Temperature Step Pyrolysis to Improve Recovered Fiber Tensile Strength and Failure Strain

Journal Article Ginder, Ryan S. ; Ozcan, Soydan - Recycling

Economic and regulatory pressures on the global composites industry have encouraged the research and development of technology for the recycling of fiber reinforced polymer composites. Although significant advancements have been made in the recycling of carbon fiber composites, more progress is needed in the recovery of glass fibers, which make up the overwhelming volume of the composites market. In this study, wind turbine blades and automotive sheet moulding compound (SMC) were subjected to a two temperature step pyrolysis. This multistep process yielded improvements in the recovered E-glass fiber’s tensile strength, by as much as 19%, and strain to failure, bymore »« less

Development of sheet molding compound solar collectors with molded-in silvered glass reflective surfaces

Conference Champion, R. L. ; Allred, R. E.

An approach to the fabrication of a line-focusng parabolic trough reflector structure which offers the potential of high performance while utilizing mass production type technology with potential for low cost is discussed. The concept is one of a molded structure of fiber reinforced plastic with an integrally molded silvered glass reflective surface. Sheet molding compound (SMC), a mixture of glass fibers and inorganic fillers in polyester resin, has been selected for evaluation as representative of reinforced plastic molding materials. The purpose of the work was to establish the feasibility of molding glass mirrors into SMC structural trough panels. If themore »« less

Correlation between failure and local material property in chopped carbon fiber chip-reinforced sheet molding compound composites under tensile load

Journal Article Tang, Haibin ; Chen, Zhangxing ; Zhou, Guowei ; ... - Polymer Composites

To develop further understanding towards the role of a heterogeneous microstructure on tensile crack initiation and failure behavior in chopped carbon fiber chip-reinforced composites, uni-axial tensile tests are performed on coupons cut from compression molded plaque with varying directions. Our experimental results indicate that failure initiation is relevant to the strain localization, and a new criterion with the nominal modulus to predict the failure location is proposed based on the strain analysis. Furthermore, optical microscopic images show that the nominal modulus is determined by the chip orientation distribution. At the area with low nominal modulus, it is found that chipsmore »« less

Closing the Loop on Automotive Carbon Fiber Prepreg Manufacturing Scrap

Technical Report Kline, Sean P. ; Maxey, Andrew T. ; Caltagirone, Peter E. ; ...

The project demonstrated how to “close the loop” on carbon fiber by integrating industrial carbon fiber scrap into new functional components in an automotive lightweighting application. The project serves as a validation of discontinuous recycled carbon fiber in a commercial context, while generating comprehensive material data throughout the production chain. To this end, the project exhibited increasing complexity as material evaluation progressed from benchtop to commercial scale through full-scale part production, with key material properties thoroughly characterized throughout the process. Of particular focus was the form of the fiber that was fed into compounding, as recycled fiber has historically beenmore »« less
