Recyclable for other processes
Composite materials are materials made from two or more constituent materials with significantly different physical or chemical properties Alex Rodriguez Yankees Jersey , that when combined, produce a material with characteristics different from the individual components.

The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter or less expensive when compared to traditional materials. One of the most common composite materials in the plastics world are reinforced plastics, which are standard plastics combined with carbon or glass fiber to produce a stronger material.

Composite materials include:

Composite building materials such as cements, concrete

Reinforced plastics such as fiber-reinforced polymer

Metal Composites

Ceramic Composites (composite ceramic and metal matrices)

Composite materials have an enormous range of applications, including anything from the construction of buildings, bridges and structures Mickey Mantle Yankees Jersey , as well as in parts such as boat hulls, swimming pool panels, race car bodies, shower stalls, bathtubs, storage tanks, imitation granite and cultured marble sinks and counter tops. Composite materials can be found in practically any industry.

Thermoplastic composites are plastic specific composite materials Babe Ruth Yankees Jersey , able to be produced on standard processing equipment such as extrusion or injection molding, however, additional materials or additives are combined with the plastic to change the physical properties to achieve a desired specification. Some of the advantages of thermoplastic composites include unlimited shelf life, faster production, and the recyclability of scrap. Thermoplastic composites offer substantial reductions in flammability, and smoke and toxicity performance, and are relatively insensitive to chemical attack. Typical uses are in automotive Aaron Judge Jersey , sporting goods, marine use, and in construction. Some thermoplastic composites for example are designed to withstand extreme temperature environments, for example in many aircraft or in industrial applications. Other composites may focus on strength or wear resistance.

It is important to note the difference between thermoplastics and thermoset materials. A thermoset is a petrochemical material that irreversibly cures following a catalytic reaction. The cure may be induced by heat, generally above 200 °C (392 °F), through a chemical reaction, or by suitable irradiation.Thermoset materials are usually liquid or malleable prior to curing and are designed to be molded into their final form Dellin Betances Jersey , or used as adhesives. Others are solids like that of the molding compound used in semiconductors and integrated circuits (IC).

In contrast to crosslinking thermosets, whose cure reaction cannot be reversed, thermoplastic composites harden when cooled but retain their plasticity; that is, they will melt once again and can be reshaped by reheating them above their processing temperature. Less-expensive thermoplastic composites offer lower processing temperatures but also have limited use temperatures.

Since the 1960s, the vast majority of composite materials for aerospace have been based on thermoset materials, especially in the United States, due to their material cost and the costs associated with conversion to new materials Sonny Gray Jersey , such as thermoplastics. However, limitations of thermoset polymers, such as their inability to be re-melted, shorter shelf-life, higher storage costs, and longer curing times, coupled with pressures to reduce weight and an otherwise evolving aerospace environment Aroldis Chapman Jersey , have opened up opportunities for thermoplastic composites.

Thermoplastic composite materials have changed the landscape of materials and are continuously being introduced into new industries, products, and applications. The following are the advantages of thermoplastic composite materials:

Affordable replacement of aluminum, steel and titanium

Improved heat tolerance

Increased toughness

Chemical resistance

Enhanced stiffness

Greater compressive strength

Longer material lifespan

Non-toxic to produce

Recyclable for other processes

Low manufacturing cost


Reshaping and reforming flexibility

Recyclable for other processes

These are the basics of composites and thermoplastic composites.

LONDON, March 4 (Xinhua) -- When British actors have been showered with top prizes from the Golden Globes to the Oscars, a seasoned acting tutor in London are trying to decode the secrets to their triumphs in Hollywood's most demanding business.

Kenneth Rea, a veteran performing tutor at the Guildhall School of Music and Drama in London C.C. Sabathia Jersey , has trained more than 1,000 actors during the past 30 years. He coached some of Britain's most famous actors, including Orlando Bloom, Ewan McGregor and Daniel Craig, before they ascended to international stardom.

In recent weeks, British actors have been laughing all the way to some of the world's most coveted acting awards, including the Golden Globes Greg Bird Jersey , the Oscars and the British Academy Film Awards (also known as BAFTA awards).

In Oscars alone, Eddie Redmayne, Benedict Cumberbatch, Keira Knightley and Rosamund Pike from Britain were all nominated for their roles in films like The Theory of Everything, The Imitation Game or Gone Girl, with Redmayne winning the best actor.

Rea said there was something unique about the British way of training actors, which helped them stand out on the world's stage and screen.
