Erosion Efficiency And Scanning Electron Microscopy ( Sem ) Of Textile Material Reinforced Polymer Composites

In the specimens, all showed a brittle fracture due to how the stress vs strain slope looked and where the Ultimate Tensile Strength was located. Also, how the composited specimens failed look consistent that there were any defects in the specimens. The 0°/90° carbon/epoxy specimen failed in the longitudinal direction because of how the fibers were aligned in that direction. The two ±45° glass/ epoxy specimen failed in the 45-degree direction do to how the fibers were aligned in the specimens. These failures would make sense because composites fail when fiber become unconnected so the epoxy failed first and then cause the fibers to fail next. The fibers individual are weak but when are combined and form a pattern with other fibers is how the strength

Dynamic mechanical analysis showed that increasing fiber content provides an improvement in the rigidity of the composites. Cardanol modified resol reinforced nanoclay composite was prepared and mechanical properties of the final composites were improved by doping a 6 wt% of nanoclay in cardanol modified resol (CMR) into the epoxy matrix. The results show that a 15 wt% of CMR in epoxy is a most suitable ratio (Nguyen et al 2007).

However, the absence of plastic deformation does not mean that composites are brittle materials like monolithic ceramics. The heterogeneous nature of composites result in complex failure mechanisms which impart toughness. Fiber-reinforced materials have been found to produce durable, reliable structural components in countless applications. The unique characteristic of composite materials, especially anisotropy, require the use of special design

Linear viscoelastic behaviour of the polymer composite with in the glass transition temperature can be addressed using cole-cole plot. Cole-cole plot is obtained by plotting loss modulus(E”) against

Composite materials have been evaluated with a matrix properties unsaturated polyester resin by conducting mechanical testing, including the pressure, compression, hardness and impact resistance.. While wood flour helped add to the balance between the original compression strength reductions up to 3 wt. wood flour and then reduce the strength. The results confirmed that the best promote and 3% by weight of wood flour consider the compression strength

Composite structures have been around since the beginning of time, but the modern day uses were first applied during World War II. Composites such as rubber tires and glass were used in structures where metal or other material structures could not be applied. The past few years, composite material structures have been used more in aircraft structures than any other time in the history of man. The main reason is that the understanding and technology are at a point were composite structures could be applied in greater use due to human understanding. Composite structures in aircraft are becoming more practical for more applications. This is based on the how/why composites are being applied, the benefits of composites, the problems/ failures of

The building materials available to engineers today are vastly improved over those of the past. One class which has seen wide spread usage in many fields are composites. These new materials first appeared on the aerospace scene in the early 1970’s, for these materials were found to provide many benefits over the previous metal-based designs.

Introduction: The available life cycle cost (LCC) models and procurement strategies do not take into consideration the varied manufacturing techniques for advanced composite materials. The increased use of advanced composite materials in aerospace

In times, metals were replaced by polymers for a few applications like reducing the weight of few parts. But in the present days new classes of engineering plastics are replacing metals at a higher level as they can be customized. Significant productivity improvement is possible by using polymers. There is a higher product performance level, cost reduction, efficiency in manufacturing, durability and enhancement of aesthetics which are all achieved simultaneously now-a-days using

materials. In the last decades, the use of natural fibers as reinforcement in polymeric composites for technical application has been a research subject of scientist. Interest in natural fibers has increased worldwide due to their low cost, low density, hardness, higher fatigue endurance, good thermal and mechanical resistivity and to their environmental friendliness. The Asian markets have been

n aeroplane is acted upon by a few forces in the sky: Lift, Drag, Thrust and Weight. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil. A composite material is a material made from two or more constituent materials with differing physical or chemical properties that when joined together, produce a material with characteristics different from the individual material. The individual component remains separate and unique from the finished structure. There are a few types of currently available composite materials, and they include carbon fibre, fiber glass and fibre-reinforced matrix systems. Almost all new aircraft these days include some composite material into their designs. The most common composite material that is used in aircraft is fiberglass. Other composite materials used includes Kevlar, which is now replacing glass fibers. Composite materials had been used commonly since

These may be classified into two categories according to the types of reinforcement used: (i) particle or short fibers and (ii) continuous fibers. For continuous fiber reinforced bio-composites, woven fabric preforms processed from natural fibers have been introduced as the reinforcements. Fabrication of laminated composite with four layers of jute woven fabrics has been done. Prior to their impregnation in the resin matrix, the jute fabrics were treated with alkali in the biaxial tensile stress state. A significant improvement of the mechanical stiffness was achieved in the composite with the fibers treated with alkali under applied stress.

In today's commercial aviation world, airlines have for a long time understood the importance of flying an aircraft as economically as possible. Advances in technology have made this possible in a number of ways, one of which is the introduction of composite material use wherever feasible. Composite materials typically offer a weight saving of between 20 and 25% when used in place of historically manufactured components made predominantly from alloyed metals. The heavier the aircraft, the more fuel it burns for a given mission, making weight reduction top priority for aircraft designers. The non-corrosive benefits, high-energy absorption and resistance to fatigue offered by composites are another attractive feature, but despite this and

Today's demand for new and properties improved materials are in high. In order to fulfill all those needs people has to go for the Composites. Metal Matrix Composites is the latest trending technology when it comes to the composite materials that posses various improvised properties that suits many property needs. It is also

Composite materials are defined as the combination of more than two materials, one of the material is called reinforcement material and another one of the material is called matrix, the reinforcement materials in the form of fiber particle, ex; - glass fiber for natural fiber, coconut shell powder matrix material and in the form of resin ex: - phenyl formaldehyde or epoxy, urea formaldehyde and so on.
