Strengths and Weaknesses of Composite
Thermoplastic Interconnect Systems
Composite Thermoplastic
A Combination of High-Tech Materials with Superior Performance
Compared to Metal Materials
 Composite: Particle and fiber additives
suspended in a Polymer resin.
 Polymer: Shapeable chemicals formed
into complex molecular chains with
specific attributes.
 Thermoplastic: engineering plastic with
extremely high-performance ratings.
Advantages of Composites
Weight Reduction and Corrosion Protection

Reduced Weight
Unlimited Corrosion Protection
Inherent shock and vibration dampening
Reduced magnetic and acoustic
signatures (stealth)
Cadmium free
Flame resistant, chemical resistant and
high-temperature tolerant
Dimensionally stable
Accepts “selective” plating for EMI/RFI grounding
Why Exactly is Composite Thermoplastic
Lighter Than Metal?
Its “Specific Gravity” or “Density” is Less

Materials Science
Amorphous Versus Semi-Crystalline Thermoplastics
 Amorphous: Random molecular
orientation
 High Strength
 Stiff
 Good dimensional stability
 Semi-Crystalline: Ordered
(crystalline) molecular structure
 Excellent wear resistance
 High heat resistance
 Resistance to caustic chemicals
Disadvantages of (Small) Composite Thermoplastic
Parts Used in Interconnect Systems
 Inappropriate for Applications Subject
to
Direct Lightning Strike such as
Exposed
Airframe Antennas
 Not Recommended for Extremely
High-Heat Applications such as Jet
Engine Sensors
 Poor Dissipater of Internally
Generated Heat (“Thermos” Effect)
 Correct Holding Tools Must Be Used
Proven Performance Applications
Composites are perfectly suited for new connector and accessory
design-ins for the next generation of high-performance systems

Selective Plating: The Glenair Approach
to EMI Grounding and Product Durability
Selective Plating Maintains an Effective Ground Path While
Eliminating Surface Scratches and Other Damage
Shown: Series 447 Composite Band-in-a-Can Backshell
Conductive Drop-In Elements
Another key to maintaining the ground path while minimizing maintenance
 Multi-function drop-ins add
flexibility and functionality to
standard composite accessory
designs
 Drop-ins shift electrical
grounding role from the (plated)
surface material to a protected
internal pathway
