Effects of silane‐modified nano‐CaCO3 particles on the mechanical properties of carbon fiber/epoxy (CF/EP) composites

“…tan δ represents the ratio of the viscous to elastic response of a viscoelastic material. [ 49–51 ] Compared to the reference CF/EP composites, there is a slight decrease in the storage modulus for the neat nano‐CaCO 3 reinforced CF/EP composites.…”

Review of quantitative and qualitative methods for monitoring photopolymerization reactions

“…on a sample of known size as a function of temperature and time, and to monitor changes (deformations) in the sample geometry. 220–227 This technique provides the following parameters: flow tendency (viscosity), shear modulus, glass transition temperature ( T g ), storage modulus ( E ′), loss modulus ( E ′′), and mechanical loss angle tangent (tg δ ). The storage modulus measures the stored energy, representing the elastic portion, and the loss modulus measures the energy dissipated as heat, representing the viscous portion.…”

“…The response of the sample to the applied force allows us to determine the gelation point and the glass transition temperature as a function of temperature. 221,222,[226][227][228][229][230] Long molecular chain polymers have special viscoelastic properties that combine the traits of Newtonian fluids with elastic solids. The mechanical characteristics of elastic solids, where stress is proportional to strain in tiny deformations, are described by the classical theory of elasticity.…”

Low‐velocity impact response of halloysite nanotube reinforced glass/epoxy multi‐scale composite. Part 1: Dynamic loading performance

“…Epoxy is a prevalent resin for industrial applications of fiber reinforced composites by good thermal stability, low density, high glass transition temperature, unique mechanical performance, and well adhesive properties. [8,9] However, epoxy is known with low resistance against crack propagation under impact loading and triggers brittle behavior because of its' high crosslink density. [10] Consequently, epoxy usage in high engineering applications is restricted.…”
