Flammability: UL94 HB. Flexural Modulus: 16.5-18.6 GPa - Dependent on the grain. Flexural Strength: 448-517 MPa - Dependent on the grain. Color: Brown. Maximum Temperature: 245° F. Tensile Strength: 8, 700 psi (Good) Impact Strength: Not Rated. Hardness: Rockwell M110 (Extra Hard) For Use Outdoors: Yes. Specifications Met: MIL-I- 24768/10. More electrically insulating than Garolite XX, these tubes are often machined into insulating washers, bushings, transformer spacers, and .... G10/FR-4 is a glass epoxy composite material that consists of glass fabric and electrical grade epoxy resin. It is flame retardant, has outstanding electrical properties, and is widely used as an. Because of the combination of continuous woven glass fabric and interwoven epoxy resin, FR-4 exhibits extremely high strength to weight ratios. For example, FR-4 plastic. — High impact strength FR-4 glass epoxy is a popular and versatile high-pressure thermoset .... Compressive Strength is used in factor of safety, maximum von Mises, maximum shear stress, Mohr-Coulomb stress, Maximum Normal stress, Tsai-Hill Criterion, Tsai-Wu. Fiberglass Technical Properties, Data Sheet, Mechanical Results. Properties: Mechanical : Tensile Stress, LW: D638: PSI: 30,000: Tensile Stress, CW. Supplier: Master Bond, Inc. Description: non-yellowing properties of the system. Master Bond Polymer Adhesive EP30- 4 produces high strength, rigid bonds which are remarkably resistant to chemicals including water, oil and most organic solvents, over the exceptionally wide temperature range of -60°F to more than 250°F. Dielectric Constant: 4.3. Dielectric strength, flame resistance, arc and track resistance, high-flex strength and high-impact strength. They maintain stability, will not melt under heat and have excellent overall electrical properties. All grades are UL® recognized. Characteristics GPO-3 is the laminate to choose when arc, flame and carbon track-resistance are needed. The EBAD TiNi™ Frangibolt® actuator is a simple and effective way to support and release loads up to 20,000 lbf. The principle of operation is simple: A Shape Memory Alloy (SMA) cylinder elongates to fracture a bolt or stud thereby achieving separation of two or more components. Standard Fastener sizes range from # 8 size screws to ¾” bolts.. FR4 Data Sheet Test/Specification FR4 Laminate Typical Thermal Stress, Solder bath 288 deg.

G-10 is stronger than the other glass-epoxy laminate G-11, but is not as good of an insulator and can’t handle quite as high of temperatures. Because of it’s strength, G-10 is difficult to machine and may require special equipment. G-10/FR-4 is available in sheet, rod, and tube. FR-4 is a fire retardant grade of G-10.
