Sereni stem fiber, due to low weight and high tensile strength was selected as backbone for graft copolymerization with binary vinyl monomeric mixture to explore its effect on percentage grafting, properties and the behavior of the modified fiber. The graft co-polymers were reinforced in a phenoplast matrix to form fiber reinforced composites and were characterized by XRD, TGA, DTA, SEM and FTIR techniques. Moisture absorbance, chemical resistance in acid and base and assessment of flexural strength, young's modulus, stress at the limit of proportionality, and hardness of the composite were studied in comparison to the phenoplast.

High strength, high toughness, and low weight make fiber-reinforced composite materials important as an alternative to traditional materials. Due to their application in different fields, such as construction, aviation, marine, automotive technologies and biomedicine, their production has increased leading to the increasement of composite wastes. New technologies for managing fiber-reinforced composite wastes have been developed to solve the issue of end-of-life of these materials. The aim of this paper is to emphasize recycling technologies used for fiber reinforced composites, and their potential reusage.

The inspection of thin basalt fiber reinforced composite materials was carried out using two nondestructive methods: terahertz time domain imaging and infrared thermography. In order to combine the information about the defects arising in examined materials the inspection results were parametrized. In order to acquire more information content, new approximation based features are proposed. Then, a knowledge extraction based multivariate analysis of preselected features’ vector was carried out. Finally, in order to integrate features distributions of representing different dynamic level of information, a multiresolution wavelet based data fusion algorithm was applied. The results are presented and discussed.

Attention has been focused recently on the interphase in continuous, unidirectional fiber-reinforced composites. In this study, the interphase region is modeled as a non-homogeneous, orthotropic material with continuously varying properties. A previously proposed solution method is used to determine the local stress fields in the constituents - the fiber, interphase and matrix - and the results are presented.

Nowadays, Natural Fiber Reinforced composites (NFCs) are emerging to be a good substitute for synthetic fiber reinforced composites as NFCs have many advantages such as low density, high specific strength, recyclability, low cost and good sound abatement quality etc. Among all types of NFCs, a vast study has been done on banana fiber and kenaf fiber reinforced composite. However, only limited work has been done on the banana fabric, kenaf fiber reinforced composite and the effect of their hybridization on mechanical properties. In this paper, an attempt has been made to study the mechanical properties of the banana fabric, kenaf fiber and hybrid banana fabric/kenaf fiber reinforced composites. Effect of alkali treatment on kenaf fiber reinforced composite is discussed in the paper. For the present work, plain-woven banana fabric and randomly oriented kenaf fiber are used as reinforcement while the epoxy resin is used as a matrix. samples are fabricated using hand lay-up and vacuum bagging method. Curing is done at ambient temperature (250C-300C) for 48h. Tensile, impact and hardness test has been performed on a specimen according to ASTM standards. Improvement in mechanical properties is observed after alkali (6% NaOH) treatment on kenaf fiber reinforced composite. Tensile testing behavior of randomly oriented kenaf fiber composite has been studied using Finite element method and results are compared with experimental investigations. This topic present big potential because it seeks to find solution for sustainable development with environmental concerns.

Fiber reinforced composites are used widely for their high strength and low weight advantages in various aerospace and automotive applications. While their use may be sought after, modeling of these material requires increasing fidelity at the lower scales to capture accurate material behavior under loading. The first steps in creating statistically equivalent models to real life cases is developing a method of rapid evaluation and artificial microstructure generation. The outlined work is capable of tracking microscale fiber positions and determining regions of localized volume fraction extrema (high and low end). Groupings of high and low volume fraction regions are called clusters and their geometry is used to characterize the microstructure. These cluster features can be evaluated for both artificial models and actual scans, allowing correlation to be established which can ultimately be used to regenerate statistically equivalent models. The results of this work show that if one feature is to be correlated, a model can be generated which matches almost exactly. But once more features are equally taken into account, the regeneration loses accuracy.

ABSTRACT Aim To make use of fiber-reinforced composite and the patient's own extracted teeth in fabricating a provisional restoration following immediate implant placement. Background Fiber-reinforced composites offer various possibilities in temporization of osseointegrating implants in the esthetic zone. Technique In this chairside technique, the patient's own extracted teeth with fiber-reinforced composite were used to fabricate a provisional restoration after immediate implant placement. Conclusion A putty index was made before extracting the teeth and placing the implants as planned. The index and crowns of the extracted teeth were used to make a nonloading, esthetic, chairside provisional restoration after immediate implant placement. Clinical significance By using the patient's own teeth for provisionalization immediately after implant placement, acceptance is greatly enhanced.
