Abstract
The addition of elastomeric thermoplastic polymers and melamine resin to the polymer matrix of composite materials for the moulding of fibre-reinforced unsaturated polyester resin improves the surface characteristics, resilience, and mouldabilty and heat resistance thereof.
Claims2
A composite moulding material with a fiber-reinforced unsaturated polyester resin base which comprises a thermoplastic copolyester-ether elastomer derived from terephthalic acid, polytetramethylene ether glycol and 1,4-butanediol and melamine resin in the unsaturated polyester resin base, wherein the melamine resin is present in an amount of from 5 to 20% by weight with respect to the composite material and the thermoplastic copolyester-ether elastomer is present in an amount of from 5 to 10% by weight with respect to the composite material.
