GRP Tank Covers: How to meet regulatory requirements in a cost-effective way
4th April 2019 Ben Hargreaves
GRP covers are widely used throughout the water-treatment industry due to their combination of mechanical performance, corrosion resistance, chemical resistance and low weight.
Finite Element Analysis: How to create a great model
18th March 2019 Romilly Close
Finite Element Analysis (FEA) is the numerical modelling of structures by breaking them down into a discrete number of ‘elements’. Elements share nodes and at these nodes physical fields such as displacement are calculated. The model is then resolved for a vector of displacements, and from this the effect of loading on the structure can be obtained.
What is Finite Element Analysis?
7th March 2019 Romilly Close
FEA is a computer-based numerical-analysis technique which involves breaking down large, complex structures (‘models’) into a mesh of discrete elements. The elements are connected to each other, at points called ‘nodes’, creating a continuous surface. The model is ascribed some material properties; it is restrained (to allow the forces to act in a physically realistic manner); a loading scenario is applied; and the FEA software generates sets of equations according to the shape of the elements and material properties.
What is Composite Ballistic Armour?
1st February 2019 Chris Hare
Ballistic Armour is a generic term for a protective layer of material that protects a person or object from projectiles. The common requirement of all systems is to dissipate the projectile energy with minimal damage to the target. This requirement for energy dissipation is where multi-layer composites can provide some advantages.
Compression Moulding: How to make High-performance Thermoplastic Composites
7th November 2018 Francisco Saraiva
An in-depth look at how compression moulding can be used for the production of high-performance thermoplastic composite components, highlighting technique as a precise and potentially rapid process for producing high-quality composite parts in a range of volumes.
What is Vacuum Bagging?
20th September 2018 Joe Carruthers
Vacuum bagging is a very flexible process for consolidating fibre-reinforced polymers of a wide range of shapes and sizes.
What is Compression Moulding?
19th July 2018 Joe Carruthers
Compression moulding is a precise and potentially rapid process for producing high quality composite parts in a wide range of volumes. It typically employs a matched metal tool in a heated (hydraulic) press to consolidate sheet materials or moulding compounds at relatively high pressures.
Composite Material Testing – The Challenges of Batch-to-Batch Variation and How to Manage Them
29th June 2018 Elliot Fleet
Statistics is a branch of mathematics that deals with managing data and evaluating logically how well it fits a preconceived pattern or model. Similarly a large part of composites R&D and materials science is concerned with generating data and using it to support a hypothesis. The use of statistical methods is therefore absolutely critical to […]
What is Resin Transfer Moulding (RTM)?
25th April 2018 Joe Carruthers
Resin transfer moulding (RTM) is a closed-mould process for manufacturing high performance composite components in medium volumes (1,000s to 10,000s of parts).
What is Dynamic Mechanical Analysis (DMA)?
22nd April 2018 Gary Foster
Dynamic Mechanical Analysis or DMA for short, is an extremely versatile and flexible analytical technique for measuring the physical properties of a range of materials.
