Composite materials

composite materials are: multiphase materials the phase distribution and geometry are

customized to get specific goals [1]

Materials made by using two or more constituentmaterials having significantly different properties

Resultant product is has different characteristicsfrom the individual components

Components keep their identification

Textile-reinforced compositematerials

Four types of material used forreinforcement:

metals, polymers, Ceramics

Composite constituents

gives synergy effect

Matrix

polyester, vinyl esteror epoxy resin

Reinforcement

Materials surroundingby matrix

FiberglassChopped Strand Mat

Emulsion or Powder Bond

Chopped FiberglassStrands


7/21

Material matrix

Countless matrixes are possible by mixing ofdifferent materials

Reinforce of textile materials is possible byusing: S-glass, R-glass, a wide range of carbon fibres,

boron ,fibres, ceramic fibres, aramid fibres,

It is possible through filaments and staplefibers, disks or plates, spheres or ellipsoids,


8/21

Materials for reinforcement

Wide range of polymers (epoxides,polyesters, nylons, etc,

Metals (aluminium alloys, magnesium alloys,titanium, etc)

Ceramics (SiC, glass ceramics, etc)

12/21

Advantages of wovenreinforcement [1]

Drapability Allowing complex shapes Low cost High resistance to impact damage Better compressive strengths after impact Low stiffness and hardness


13/21

Composite properties depends upon: Type of fiber Weaving parameters Stacking Orientation Yarn twist

Braided reinforcement

PVC ClearBraided Reinforcement Hose


16/21

Why braiding

To make stronger, stiffer, tougher, moredamage tolerant composite

improve manufacturing efficienciesdramatically


17/21

Braiding

It is a process in whicha pattern formed byintertwining three ormore strands of flexiblematerial such as textile

fibres, wire, or humanhair.

A wide sheet of clothcan be formed byusing two separate,

perpendicular groupsof strands (warp andweft


18/21

Knitted reinforcement [1]

knittingreinforcement is usedto develop net and

mesh

These can adaptcomplex shapes,higher drapability,


19/21

Stitched fabrics [1]

It is a direct approachto improve:

Thickness strength of the

materials

improve their damagetolerance,

More flexibleproduction system
