There are many different types of polymers that can be used as a matrix for composite materials. In this explainer, we’ll look at ways in which these materials can be categorised and highlight the key differences between them. Let’s start with perhaps the most fundamental categorisation… Thermoplastic or Thermosetting? Thermoplastic Thermoplastics can be heated and […]

The primary driving force behind the emergence of thermoplastic composites into the mainstream is the automotive industry. And the things that drive the automotive industry are weight saving and low cost, so how do thermoplastic composites meet the challenge?

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.

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.

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 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.

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 […]

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).

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.
