The conserved C-terminal domain of spider tubuliform spidroin 1 contributes to extensibility in synthetic fibers
… focused on the production of dragline silks from synthetic spider silk gene products. Here we report the first mechanical analysis of synthetic egg case silk fibers spun from the Latrodectus hesperus tubuliform silk proteins, TuSp1 and ECP-2. We provide evidence that recombinant ECP-2 proteins can …

Oil sorption behavior of fibrous substrates
… addition to the pollution caused due to the oil, synthetic sorbents are a hazard to the environment. Synthetic fibers like polypropylene occupy a major share of the oil spill cleanup industry. Being non-biodegradable, the oil soaked synthetic sorbents pose a risk to the environment when they are …

Biomimicry of the spider silk spinning apparatus
… both very strong and extensible. Even though the fibers outperform many synthetic and natural materials, it is impractical to collect industrial amounts of silk from spiders due to their cannibalistic and venomous nature; they cannot be farmed like the commercial silk worm Bombyx mori. Thus, …

Three dimensional weaving of tubular structures
… If living tissues could be used instead of synthetic fibers, the body's immune system would not reject the repair. This thesis covers the design and implementation of a weaving machine that is capable of weaving living tissue into three dimensional tubular structures. This prototyped machine …

Flowable Fibrous Concrete For Thin Pavement Inlays
Synthetic fibers within a flowable fibrous concrete (FFC) mixture were characterized by relating their spatial distribution and orientations, determined from x-ray computed tomography (CT), with the measured toughness or fracture energy response of a FFC specimen. This new type of concrete, FFC, …
