Application Spotlight

This steel housing needed to be firmly clamped into place for machining, but its irregular shape proved difficult to clamp. A 3D printed fiberglass-reinforced jaw provided a custom geometry that was strong enough to withstand clamping forces without marring the part.


What is high strength high temperature fiberglass?

Extremely thin strands of glass bundled together into a fiber. Fiberglass is traditionally used in composites for boat, automobile, and aircraft manufacture.

How strong is high strength high temperature fiberglass?

HSHT fiberglass has a flexural strength of 420 MPa (71 ksi) and a tensile strength of 600 MPa (87 ksi). For more information on HSHT fiberglass material properties, check out the data sheet.
