Cotton, paper, and woven glass fibers
How can laminations be constructed using fabric materials?
By embedding cotton, paper, or woven glass fibers in a plastic matrix.
What is the purpose of embedding fabric materials in a plastic matrix to create laminations?
To form a composite material with enhanced properties.
Why is it important to use fabric materials like cotton, paper, or woven glass fibers in laminations?
To provide strength and reinforcement to the laminated structure.

By enhancing the mechanical properties of the laminated material.
Match the strengthening mechanisms in composites with their descriptions:
Fiber bridging = Mechanism where fibers prevent crack propagation Matrix hardening = Mechanism where matrix material resists deformation Particle reinforcement = Mechanism where particles enhance load-bearing capacity Interfacial bonding = Mechanism where strong bond between matrix and reinforcement improves strength
Match the fracture modes of particle reinforced composites with their characteristics:
Interfacial debonding = Delamination at interface due to weak bonding Particle pull-out = Particles pulled out from matrix due to applied stress Matrix cracking = Cracks forming in the matrix material Fiber breakage = Failure of fibers within the composite
Match the applications of Al-SiC composites with their industries:
Aerospace industry = Applications in aircraft and spacecraft components Automotive industry = Applications in automobile parts for improved performance Marine industry = Applications in shipbuilding and marine structures Sports equipment industry = Applications in manufacturing sports gear and equipment
Match the mathematical models for predicting mechanical properties of composites with their purposes:
Rule of mixture = Predicts composite properties based on constituent properties and volume fractions Halpin-Tsai model = Predicts elastic modulus of composites with aligned fibers Cox model = Predicts tensile strength of particle reinforced composites Mori-Tanaka model = Predicts overall elastic behavior of composites with different constituents
