Man-made technical fibres, such as carbon and glass, present unique challenges when measuring dimensional and mechanical properties. At Dia-Stron we constantly strive to design and manufacture the most effective testing systems for these technically challenging materials. The mechanical characterisation of these fibres or filaments, especially in uniaxial tensile deformation, is routinely measured to understand and to predict the behaviour of composite parts.
Our unique approach to sample mounting allows a typically lengthy testing process to be dramatically reduced in terms of time and resources. We achieve this by utilising our bespoke tab design, which aligns and secures the sample using various UV curing adhesives. This unique approach allows samples to be mounted en masse and in advance of testing studies. Storage cassettes are loaded onto automated systems which reduce testing variability and human error.
Our systems are capable of measuring dimensional and a variety of mechanical deformations, including but not limited to dimensional, tensile, fatigue, bending and torsion.

Carbon or ceramic filaments have been used for decades to mechanically enhance the strength and elasticity of polymer based matrix plastics. Though carbon fibre alone is brittle, when fused with resins and adhesives it can form composite parts capable of outperforming traditional materials, such as steel, aluminium and plastic. Individual filaments are extremely fragile and therefore […]Continue Reading
Natural fibres vary in shape and size, occasionally featuring additional surface characteristics. This increased variability requires a different approach for dimensional and mechanical analysis to regular, repeatable fibres such as carbon. The FDAS770, a non-contact direct diameter measurement system, utilises a high-frequency scanning laser, lending itself perfectly to irregular fibres whilst being insensitive to external vibration.

Glass fibre presents a unique challenge when specifically focusing on dimensional measurement: transparency. The smoothness and regularity of the fibre surface also poses potential issues with mounting samples using adhesion. Our sample mounting tab method and dimensional/mechanical capabilities allow our systems to process glass filament samples to produce high quality data. To tackle glass fibre testing, the […]Continue Reading
