Thermo-set based composites using epoxy resin systems currently dominate the composite industry. Glass-reinforced epoxy composites are extensively used in the structural composites of aircraft industry due to low shrinkage, ease of fabrication, chemical resistance, and higher mechanical and electrical properties. The above characteristics coupled with techno-economic considerations are mainly r...

This work presents a procedure to transform an isotropic nonlinear and rate-dependent material model into orthotropic. transformation relies on fast computation modifying the inelastic evolution along any desired direction. With this concept, constitutive law of pure isotropic, is fully preserved. paper shows direct application describe response unidirectional (UD) or bidirectional (BD) fiber-r...

An experimental approach is developed and utilized to characterize the fiber-matrix interfacial debonding mechanism its effect on matrix cracking in unidirectional (UD) fiber composites. Local deformation response at interface first studied by analyzing strain fields vicinity of macro fibers single-fiber samples. A practical for identification normal cohesive behavior presented implemented a fi...

Concurrent analysis of composite materials can provide the interaction among scales for better design, analysis, and performance prediction. A data-driven concurrent n-scale modeling approach ( $$\text {FExSCA}^\text {n-1}$$ ) is adopted in this paper woven composites utilizing a mechanistic reduced order model (ROM) called Self-consistent Clustering Analysis (SCA). We demonstrated multiscale t...

Adhesion of the reinforcement to the polymer matrix is essential for load transfer from the polymer matrix to the reinforcement material in fiber-reinforced composites. The reversible Diels–Alder reaction between a furan-functionalized epoxy-amine thermosetting matrix with a maleimide-functionalized glass fiber was used to impart remendability at the polymer–glass interface for potential applic...

Interphases in unidirectional fiber-reinforced composites under transverse loading are modeled using an advanced boundary element method (BEM) based on the elasticity theory. The interphases are treated as elastic layers between the fiber and matrix, as opposed to the springlike models in the BEM literature. Stress intensity factors for interface cracks between the interphase and the matrix are...
