Materials science consulting and analysis
GLASSES & CERAMICS
Glasses and ceramics are used in products that we encounter in our daily lives, such as windows, aquarium, tiling and flooring and toilets. They are characterized by excellent wear resistance, very high hardness, and strength. However, in certain conditions, they can demonstrate limited ductility and fracture toughness. Our Materials Engineering team has extensive knowledge in linear elastic fracture mechanics in the brittle failure behaviors of these materials and can determine the causes of failure through the investigation and testing.
POLYMERS & PLASTICS
Polymer materials are composed of organic contents (carbon based), which form monomer units and are bonded together, allowing for tailored chemical and mechanical properties. These are some of the reasons why so many of the products we see on a daily basis are composed of polymers. While these materials are usually stable chemically and physically, certain conditions, uses, and environments can cause them to degrade and fail, often catastrophically, resulting in water escapes, fires, and other losses.
The advancement of human civilization is shown through the eras of human development: stone, bronze and steel. These show that humanity is tied to our usage of materials, and also that metals are fundamental to our lives. In our everyday lives, we see metals and alloys in innumerable uses, since their tailorable properties make them ideal for a wide variety of products and environments, even those we couldn't have envisioned mere decades ago. However, metallic materials can and do fail. They can fail through overload, fatigue, corrosion and a multitude of other phenomenon. CEP-Sintra has equipped its laboratories with metallurgical facilities, allowing our experts to determine the causes of metal failures.
Many modern technologies require materials with unusual combinations of properties that cannot be met by conventional metal alloys, ceramics, and polymeric materials. This is especially true for materials that are designed for applications in the aerospace or transportation industries, or used in extreme environments, such as undersea. Ideal materials for these applications will have tailorable properties including density, fracture strength and toughness, abrasion and impact resistance, high corrosion resistance. The composite group of materials has the capability for formidable combinations of the above mentioned properties. Generally speaking, a composite is considered to be any multiphase material that exhibits a significant proportion of the properties of both constituent phases such that a better combination of properties is achievable. CEP-Sintra has the equipment and expertise to analyse and to determine the cause of composite materials fractures and failures.
