SASCOM Seminar Series - Growing Together the Saudi Arabian Society for Composite Materials

This short presentation aims at introducing the Saudi Arabian Society for Composite Materials (SASCOM) to is members and future members, so we can grow together a sustainable dynamics for composite technologies in Saudi Arabia and the region.

The Saudi Arabian Society for Composite Materials (SASCOM) aims to facilitate strong collaborations between scientists, engineers, educational and industrial partners interested in the study, manufacture and use of composite materials and structures. By providing a dynamic and high-level network of experts, we aim to contribute to increasing the societal impact of composite materials that have an important role to play in the Saudi economy.

Following this short introduction, we will overview a list of recent research direction and hot topics in composite science and engineering, that could be seeds for large scale collaborations between our members.
Extensive time will also be given to our audience to share for suggestions about potential activities of the Society, and what could be the best offering to serve their need.

SASCOM Seminar Series - Thin-Ply Composites: Towards Lighter and Multifunctional Aerospace Composite Structures

In recent years, important progress has been made in the development of composite laminates using thinner pre-impregnated plies down to about 20 micrometers instead of ~200 micrometers for traditional composites. The motivation for this trend towards the development of thin-ply composites is not only to allow the production of thinner and lighter laminates for lightweight structures, but also to provide enhanced effective design space for laminate optimization as well as improved strength and damage resistance thanks to positive size effects.

The first prime benefit of using thinner plies is the ability to optimize among a larger number of ply orientations for a given laminate thickness or to allow the manufacturing of ultra-thin laminate for example for flexible structures or skins for lightweight sandwich panels. The second benefit is that thin-ply composites present a very significant performance advantage over traditional composites due to delayed delamination and transverse cracking. Indeed, it has been shown that multi-axial laminates made of thin-ply composites can reach an ultimate strength and first ply failure close to the ultimate strain of the fiber. Thirdly, as it will be presented in this talk, thin-ply composites are also ideally suited to develop multifunctional structures that integrate electronic circuits to interconnect active components such as radio communication, sensors for IoT.

In this seminar, an overview of the mechanics of thin-ply composites will be presented to highlight the main performance advantages and drawbacks of this new class of composites [1,2]. To explain those mechanisms, a multiscale model of transverse cracking in thin-ply laminates has been developed and provides important insight on the cause of the observed experimental scaling of in-situ strength and apparent toughness of thin-ply quasi-isotropic laminates [3,4].

Applications examples on the use of thin-ply composites in aeronautic structures will be presented where a potential weight reduction up to 30% has been demonstrated compared to standard composites while reaching a similar or better production rate by using automation and optimized design for manufacturing. Finally, the use of thin-ply composites in the manufacturing of smart multifunctional structures will be presented.

SASCOM Seminar Series - Thermoplastic composite solutions for mass markets: Opportunities and challenges

Thermoplastic composites are increasingly being considered for large volume applications that involve replacing incumbent materials such as metals. The Consumer Electronics space in particular, offers an interesting opportunity to capitalize on the performance of fiber-reinforced composites because of the general need to go to thinner structures while being frugal with changes in weight in applications like mobile computing and communications [1]. These applications tend to lean towards a large part build volume, typically in the range of a 100k to 1 Million parts per year. The model platform also tend to be short lived, which means there is a constant need to stay on top of what the customer’s perceived needs are and adapt accordingly with new models. This makes the designed flexibility of the manufacturing line very important. All of this creates the perfect opportunity to explore automation driven production approaches. The development challenges however for this automation driven production approach were identified to be: high speed production, with minimal scrap and minimal human intervention resulting in low conversion costs, while still maintaining a high degree of flexibility.

An end-to-end automated manufacturing line in which all steps are integrated and automated into a consolidated system, thus producing a constant production flow was developed through a partnership between Airborne and SABIC. In many cases, automation technology is developed separately from material development community, yielding sub-optimal results. Here we take a holistic view and develop the most effective technology taking into account all these aspects, in material development, automation and product design. The technology developed is also suited for high-end products in other markets, such as automotive, aerospace or sporting goods.

The ultimate goal of this line is to be fully digital and designed for minimal human intervention. It features full in-line inspection of the input material as well as the finished part. This information is processed in real time allowing online process optimization to adapt the process settings on-the-fly, based on the measured data and required output quality. Ultimately, this can deliver flexibility in order to accommodate changes that the industry demands.

SASCOM Seminar Series - Applications of Nonmetallic Composite Materials in Oil and Gas Services: Deployment and Future Perspective

Nonmetallic Materials produced using chemicals and polymers originating from the hydrocarbon value chain are becoming increasingly important in our society. Nonmetallic materials are used to mitigate corrosion in oil and gas facilities, which are mostly made of carbon steel and prone to corrosion due to exposure to common oil field fluids, H2S, CO2, and even microorganisms. The usage of nonmetallic products in Saudi Aramco has increased significantly in recent years as a result of the benefits of this material in corrosion prevention, speedier installations, and life cycle cost reductions. Apart from the traditional nonmetallic applications in water and low pressure services, which began in the 1970s, we have now successfully installed almost 10,000 km of pipes in a variety of applications. 

Nonmetallic materials in replacing incumbent material systems, their features, and essential components that need to be looked into for wider and augmented penetration will be discussed in this talk. We’ll also discuss the growth of cutting-edge materials like carbon fiber, their potential uses, and work required to promote adoption

SASCOM Seminar Series - Carbon Nanostructures of Oil Fly Ash as Reinforcements for Different Polymers

Polymer nanocomposites are promising for application in various products. However, effective additives as mechanical reinforcements at a low cost are needed. From the other hand, oil fly ash, which is hugely available in Saudi Arabia and other countries might solve this issue. This material is produced as a biproduct due to the use of crude/heavy oil as a fuel in power and desalination plants. The majority of such fly ash consists of unburned carbon, which can make up 80-95 wt% of the ash. A considerable part of these carbons has graphitic structures. This oil fly ash in its nano and micro structures is found to be quite suitable for its use as a mechanical reinforcement. Among such structures, carbon nanotubes (CNTs) derived oil fly ash were found to have attractive structural and mechanical properties. These CNTs were evaluated as reinforcements for different thermoplastics like high-density polyethylene, polycarbonate, polypropylene, and polystyrene. Significant enhancement in the mechanical properties at a low weight fraction mainly the tensile strength, Young’s modulus, stiffness, and hardness, were observed. The other form of oil fly ash is nanoparticles, produced in our lab was evaluated for high-performance epoxy matrix system. The obtained results showed significant enhancement in the stiffness of the nanocomposite material by 60% over that of the pure epoxy matrix system. These results might be useful to recommend oil fly ash at its nano and micro structure for different polymers.
