Fiber-reinforced tough hydrogels
Using strong fibers to reinforce a hydrogel is highly desirable but difficult. Such a composite would combine the attributes of a solid that provides strength and a liquid that transports matter. Most hydrogels, however, are brittle, allowing the fibers to cut through the hydrogel when the composite is loaded. Here we circumvent this problem by using a recently developed tough hydrogel. We fabr...

ment methods and two spec/imen diameters. Flexural strength and modulus of woven glass fiber-reinforced specimens werc significanLly greater than those without woven glass fiber (p<O.OD, Likewise, comprossive strength of reinforced specimens was signifieantly greater than those without woven glass fiber (p<O.Ol), except for specimens rcjnforced with woven glass fiber oriented at a tilt directio...
متن کاملCarbon Fiber Reinforced Bismaleimide Composites
Bismaleimide (BMI) resins are developed very rapidly due to the demands of the defense and aerospace industries. They are cross-linked polymers which process like epoxy resins but have an upper use temperature of 230°C, compared to the epoxy upper use temperature of 175°C. Also due to the available intrinsic properties of BMI resins such as higher thermal stability and lower toxicity than those...
متن کاملShear Strength of Fiber-Reinforced Clayey Sands
Consolidated-drained triaxial compression tests were conducted to compare the stress-strain and volume change response of sands and clayey sands reinforced with discrete randomly distributed poly-propylene fibers. The influence of various test parameters such as fiber content (0.0%, 0.5% and 1.0% by weight), clay content (0%, 10% and 20% by weight), relative density (50% and 90%) and confining ...
