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...

For effective applicability of reinforced cork, cork composites with metal, glass fiber, and carbon fiber were developed, the effects reinforcing materials on mechanical properties investigated. The bending moduli elasticity (MOE) in 32.7–35.9 MPa range, while strength values 1.62–1.73 range. performance decreased order cork-metal > cork-carbon cork-glass fiber. MOEs improved by 29%–41% comp...

STATEMENT OF THE PROBLEM Sufficient adhesion between silorane/methacrylate-based composites and methacrylate impregnated glass fiber increases the benefits of fibers and enhances the mechanical and clinical performance of both composites. PURPOSE The aim of this study was to evaluate the compatibility of silorane and methacrylate-based composites with pre-impregnated glass fiber by using flex...

Layered composites subject to impacts can fail by delamination, i.e. by debonding between laminae, if the stress waves cause damaging phenomena to take place mainly within the resin-enriched interlaminar phases. To simulate delamination at the structural level, processes dissipating energy are lumped onto fictitious zero-thickness interlaminar surfaces, and softening interface constitutive laws...

Abstract The reduction of weight elements is considered as a major objective several manufacturing companies. This will help in growing application sections the used fiber composites for important structural elements. Modern metal laminate (FML) having lightweight properties established to be instead other substances different applications including those related aerospace industrial sector. Fi...

We investigated the effects of hygrothermal aging on the tension–tension fatigue behavior of unidirectional (UD) glass/polydicyclopentadiene (pDCPD) composites. Samples were immersed in deionized (DI) water and salt water, and glass/epoxy composites were used as a benchmark for comparison. Composites of pDCPD showed less water uptake and superior fatigue performance compared to similarly aged e...

The use of fiber-reinforced composite materials has widely spread in various sectors, including aerospace, defense, and civil industry. assessment these heterogeneous material systems is important for safer risk-free applications contributed to the need self-sensing composites. This work focused on development piezoresistive composites, prediction their performance structural health monitoring ...

Natural fibers have been used to reinforce materials for many years. More currently they have been employed in combination with plastics. Many types of natural fibers have been investigated for use in plastics including flax, hemp, jute, cotton and banana. Natural fibers have the advantage that they are renewable resources and have marketing appeal. These agricultural wastes can be used to prep...

BACKGROUND Flexural strength (FS) of denture base resins (DBRs) had been improved by reinforcing it with different glass fibers. However, a limited data are available on the effect of glass fiber reinforcement with conventional heat-cured resin after prolonged water storage. AIMS AND OBJECTIVES This study aimed to evaluate the reinforcing effect of novel S-glass and nylon fibers on the FS of ...
