Our Specialization
Composite & Fabrication Stream focus on strong lightweight structures that utilize composite materials and joining techniques. We manufacture FRP, bonded composites, metal-to-composites, and welded metal coupons for tensile, compression and bending test. We computerize characterized material to simulate load conditions and simulate production workflow for optimized manufacturing. We employ Autoclave curing, robotic welding, CNC sheet metal forming to meet tight tolerances, and fatigue test, environmental test to evaluate component limits. We measure component damages by X-Ray, ultrasonic test, eddy current, penetrant, magnetic particle tests, and resume structural performance using bonded, bolted repair techniques with alignment to aviation, construction, ASTM and ISO standards.
