Use of composite laminates is found in various applications such as aircraft and automotive, sports, rocket parts and civil structures. Resin system of the polymer composites enacts a crucial role of binding the reinforcements properly to provide good mechanical properties. The presence of any kind of filler alters the properties of resin system which in turn also alters the mechanical behaviour of composite laminate. In the present work an attempt has been made to enhance the mechanical performance of glass fibre epoxy composites by embedding nano calcium carbonate particles in resin system. These particles were added in different weight fractions like 1, 3 and 5% and the response of GFRP nano composites were recorded under flexural and shear loads. Composite laminates with 3% wt. of nano particles have shown considerable improvement among the other laminates.

Tensile experiments were conducted on composite–composite joints and composite–steel joints with countersunk bolts while three-dimensional finite element models using progressive damage method on composite were developed to simulate bearing failure of joints. Experimental results showed good repeatability and bearing damage showed obvious difference between the two kinds of joints. Solid elements were chosen to model all the parts and laminates were partitioned into actual number of plies in order to gain accurate stress distribution and damage profile in each ply. A 3D Hashin-type criteria and degradation rules were implemented using a user subroutine in ABAQUS. Numerical results had good agreement with experimental results considering clearance effects. Composite–steel joints showed better carrying capacity than composite–composite joints according to load–displacement curves and damage evolution processes. Delamination were more severe in composite–composite joints indicating that it is necessary to pay attention to designing composite laminates and structures under certain load condition.

Layered fiber-reinforced composite structures are susceptible to crack initiation and growth in the resin-rich layer between plies. Delamination represents one of the most prevalent life-limiting failure modes in laminated composite structures. Interlaminar fracture mechanics represents one approach to assess the damage tolerance of composite structures. This paper is organized into two major sections. The first sections introduces interlaminar fracture mechanics and test methods that have been developed to characterize the Mode I, II and III interlaminar fracture toughness of composite laminates. In the second section, the role of interlaminar fracture mechanics in assessing damage tolerance of composite structures is defined through the following case studies: residual compression after impact strength, instability related delamination growth in compressively loaded laminates and delamination growth in composite laminates with discontinuous internal plies.

This Paper studies the important role of the Composites, in the complex process of designing Solar Refractive Concentrators, that would be unthinkable and unrealizable without their employment, when having necessary the technical characteristics that they make them viable. It contributes, also, the methodologies followed for the accomplishment of optimal prototypes, by means of Numeric Methods of simulation (Finite Elements), experimental on models and of characterization of composite laminates.
