“…Similarly to tension, the molecular behaviour of the resin at CT is reflected in the compressive properties: the compressive modulus and strength of the resin increase and the failure strain decrease with decreasing temperature [71,72].…”

“…We used microbial community analyses based on 16S ribosomal RNA sequencing and genome-resolved metagenomics, and mechanical and materials characterization based on thermogravimetric analysis (TGA) and Fourier-transform infrared spectroscopy (FT-IR) to study the impacts of microorganisms on the degradation of polymer composite materials. We fabricated vinyl ester-based carbon fiber-reinforced composites in-house using vacuumassisted resin transfer molding process, which is commonly used for fabricating such composites 18,42,43 . These composites were fabricated using layers of woven carbon fiber bundles and stacking them in the thickness direction, followed by infiltration of vinyl ester resin through the dry fabric.…”

Polymer composites are attractive for structural applications in the built environment due to their lightweight and high strength properties but suffer from degradation due to environmental factors. While abiotic factors like temperature, moisture, and ultraviolet light are well studied, little is known about the impacts of naturally occurring microbial communities on their structural integrity. Here we apply complementary time-series multi-omics of biofilms growing on polymer composites and materials characterization to elucidate the processes driving their degradation. We measured a reduction in mechanical properties due to biologically driven molecular chain breakage of esters and reconstructed 121 microbial genomes to describe microbial diversity and pathways associated with polymer composite degradation. The polymer composite microbiome is dominated by four bacterial groups including the Candidate Phyla Radiation that possess pathways for breakdown of acrylate, esters, and bisphenol, abundant in composites. We provide a foundation for understanding interactions of next-generation structural materials with their natural environment that can predict their durability and drive future designs.

40Polymer composites have become attractive for structural applications in the built environment 41 due to their lightweight and high strength properties but can suffer from degradation due to 42 environmental factors. While impacts of abiotic factors like temperature and moisture are well 43 studied, little is known about the influence of naturally occurring microbial communities on their 44 structural integrity. Here we apply complementary time-series multi-omics of biofilms growing on 45 polymer composites and materials characterization to elucidate, for the first time, the processes 46 driving their degradation. We measured a reduction in mechanical properties due to molecular 47 chain breakage and reconstructed 121 microbial genomes to describe microbial diversity and 48 pathways associated with their degradation. The composite microbiome is dominated by four 49 bacterial groups including the Candidate Phyla Radiation that possess pathways for breakdown of 50 acrylate, esters, and bisphenol, abundant in composites. Overall, we provide a foundation for 51 understanding interactions of next-generation structural materials with their natural environment 52 that can predict their durability and drive future designs. polymer composite materials (referred to as polymer composites) have become 82 an attractive option for infrastructure due to their lightweight, high stiffness and high strength to 83 weight ratios 1 , which are favorable properties for enabling high fuel efficiency and towards 84 increasing mobility. In addition, polymer composites have extremely high corrosion resistance 85 compared to conventional materials like steel which are easily corroded. Therefore, although initial 86 installed costs of polymer composites and steel are comparable, life-cycle costs of polymer 87composites are expected to be significantly lower. Currently, polymer composites have a prevalent 88 use in a large range of infrastructure 2 including pipelines, utility poles, prefabricated pavements, 89 renewable energy harvesting, chimneys or flues, rapidly deployable housing, decking for marine 90 and naval structures and advanced retrofitting. Recent studies 3,4 have demonstrated that polymer 91 composites, when designed appropriately, can provide a cost-effective alternative to current 92 structural materials used for primary loading-bearing elements in civil infrastructure. Specific civil 93 infrastructural applications of polymer composites include but are not limited to retrofitting of 94 existing concrete structures, strengthening of steel structures, as internal reinforcing rods in 95 reinforced concrete structures, in new construction as structural members 5
