The Performance of Filava-Polysiloxane, Silres® H62C Composite in High Temperature Application

Abstract

The research aim is to investigate the performance of novel enriched mineral fibres (Filava) in polysiloxane SLIRES H62 resin. Specimens were manufactured using a vacuum bagging process and oven cured at 250 °C. Specimens were prepared for flexural testing according to BS EN ISO 14125:1998 to obtain flexural strength, modulus, and elongation. The mechanical strength was compared to similar composites, with the aim of determining composite performance index. The flexural modulus (9.7 GPa), flexural strength (83 MPa), and flexural strain (2.9%) were obtained from a three-point bending test. In addition, the study investigates the thermal properties of the composite using a state-of-art Zwick Roell high temperature tensile rig. The results showed Filava/Polysiloxane Composites had an ultimate tensile strength 400 MPa, Young’s modulus 16 GPa and strain 2.5% at 1000 °C, and no smoke and ash were observed during pyrolysis. Ongoing research is currently taking place to use Filava-H62 in fire-retardant enclosure for lithium-ferro-phosphate Batteries used in electric trucks.

Novel Reactive Flex Configuration in Kiwi Wing Foil Surfboard

“…The experimental results become inaccurate due to inaccuracy in second moment of inertia. Furthermore, the set-up of fibre/resin volume fraction in the FEA simulation was based on the assumption of fibre volume fraction consistency, which makes it difficult to find a suitable solving model [3].…”

“…The trade price of ordinary prepreg CFRP is prohibitively high for many other industry sectors, as follows: £26.0/kg, compared to raw unmachined steel, aluminium and titanium at £10.30/kg, £20.36/kg and £50.5/kg, respectively [2]. The trade price of Filava woven fabric is £25/kg [3].…”

The trade price of Filava woven fabric is £25/kg [3]. Fuselages are usually fixed to the mast and are made from generally solid CFRP; however, for high performance application, titanium has been used in the Kiwi model fuselage shown in Figure 1b to obtain high strength during manoeuvring.…”
