Fiber Reinforced Polymer (FRP)
Is a composite material made of a polymer matrix reinforced with fbers. The fbers are usually glass fbers, the polymer is usually an epoxy, vinylester or polyester thermosetting plastic, and phenol formaldehyde resins are still in use. FRP’s are commonly used in the aerospace, automotive, marine, construction industries and ballistic armor.
Compression Molding
When the raw material containing reinforced fbers are compressed & molded at certain pressure & temperature the fnal outcome would be called a FRP molded product, which qualifes it as a fber-reinforced polymer. More typically the polymer preform used in compression molding does contain reinforcing fbers. In compression molding, a “preform” or “charge”, of SMC, BMC is placed into molding cavity, the mold is closed and the material is formed & cured inside by pressure and heat.Compression molding offers excellent detailing for geometric shapes ranging from pattern and relief detailing to complex curves and creative forms, to precision engineering all within a maximum curing time of 20 minutes.
Advantage & Limitation
FRP allows the alignment of the glass fbers to suit specifc design programs. Specifying the orientation of reinforcing fbers can increase the strength and resistance to deformation of the polymer. Glass reinforced polymers are the strongest and most resistive to deforming forces when the polymers fbers are being exerted with a parallel force
